Key: [Opt] = Optimization [Bug] = Bug Fix [Imp] = Improvement on bug, but major problems still exist [New] = New Feature [Chg] = Changes Previous Functionality [Kis] = Known Issue [Wrk] = WorkAround [WrB] = WorkAround broken as a result of bug fix. [Nlr] = No Longer Reproducible, Reason Unknown. Usually a consequence of some other fix. [FYI] = Please note. [Tip] = Here's a handy piece of information. (All) = All (Mac) = Mac OS compiled applications, and possibly the IDE. (68K) = 68K compiled applications, and possibly the IDE running on a 68K Mac. (Win) = One of the flavors of Microsoft Windows (NT, 9x, 2000, Me) (IDE) = REALbasic, the application (OSX) = Mac OS X DP4 or later (Car) = Carbon version of the Mac OS or IDE (CarbonLib 1.2.5, Mac OS 8.6 and higher, and Mac OS X 10.0 or later) 4.0.1b3 -- 2002/01/04 [Fix] (IDE) App Deactivation: switching from REALbasic to some other app and back now reliably deactivates and reactivates REALbasic (including hiding the floating palettes, etc.). [Fix] (All) Database: accessing the error code or message no longer crashes. [Fix] (All) Database -- Postgres Plugin: updating boolean fields now work. [Fix] (IDE) External Windows: can now be renamed. [Fix] (IDE) External Project Items: can now be relocated even when the external item is not found (extends an earlier fix for movies, pictures, and sounds, to things like external windows and classes). [Fix] (All) Listbox: Headers of the listbox now depress again. Broken for Win32 and OS X in 4.0.1b1 [Fix] (All) Serial Control: data not read before additional data arrives is no longer lost; fixes bug introduced in 4.0a4. [Fix] (Mac) TabPanel: background color of checkboxes (etc.) on a TabPanel is now correct on MacOS versions prior to 8.5. 4.0.1b2 -- 2002/01/03 [Fix] (IDE) Build Settings Dialog: REALbasic now will no longer overwrite the project file with a Mac or Windows built application. This protection was in place previously only for Mac applications and didn't work in cases where the name was the same but the capitalization was different. [Fix] (OSX) Canvas: focus ring is now completely erased when a canvas loses the focus. [Fix] (Car) EditField: option-drag of text within a field now does a copy rather than move. [Fix] (Car) EditField: drop of text is no longer accompanied by an improper "fly-back" effect. [Fix] (All) Listbox: Editable Cells now scroll into view even when the row and column of the editable cell are both 0. [Fix] (Win) Listbox: Editable Cell contents are no longer invisible when the cell initially gets the focus. [Fix] (Win) Listbox: Editable Cells now invoke the CellLostFocus and CellGainedFocus events when the current editable cell changes. [Fix] (All) Office plugins: objects passed back as variants are now accessible instead of returning nil. For example, getting the Style class of a Paragraph in Word returns a variant object, which you can now cast as a WordStyle object. [Fix] (All) Office plugins: getter/setter functions with variant parameters are now optional. For example, getting/setting the Range of an Excel Spreadsheet no longer requires 2 parameters. [Fix] (Mac) RbScript: arrays used in functions or subs no longer cause random corruption of local variables and unpredictable crashes. [Fix] (All) RbScript: Oct function no longer returns spurious trailing zero. [Fix] (All) RbScript: properties declared Private are now accessible to subclasses. [Fix] (All) Rb3DSpace: SkyColor is no longer lost when this control is resized. 4.0.1b1 -- 2001/12/21 [Imp] (Mac) Listbox: Improved speed of selecting rows [Imp] (Mac) Listbox: Other speed improvements. [Fix] (Mac) Window: Keydown no longer leaks memory. [Fix] (Mac) Listbox: No longer slows down over time. [New] (Win) Listbox: Drastically reduced flicker when scrolling. [Fix] (All) Listbox: Reduced flicker caused by clicking on a listbox header. [Kis] (Win) Listbox: Editable Cell contents are initially invisible. [Chg] (Mac) Build Settings Dialog: Increased the preferred memory to better reflect new features of 4.0. 4.0 -- 2001/12/18 [Imp] (Win) Listbox: The second click in an editable cell, now moves the cursor. [Fix] (All) Listbox: Pressing "Return" or "Esc" in an editable cell now causes the focus to return to the listbox. [Fix] (Mac) Listbox: The focus ring is now removed after a "Return" or "Esc" in an editable cell. [Fix] (All) Listbox: The listbox no longer scrolls to the right after a return followed by an additional keypress. [Fix] (Win) Listbox: Added support for multiple discontiguous selection on Win32 using the control key. [Fix] (Mac) RbScript: code generator bug which caused running scripts to do all sorts of incorrect things (freeze, report incorrect data, take the wrong branch of an "if" for no good reason, etc) has been repaired. [Fix] (Mac) RbScript: user-written functions which accept multiple non-floating-point parameters no longer receive bogus values in all parameters but the first. [Fix] (Mac) RbScript: Scripts which use ByRef parameters no longer fail a Parser.cpp assertion. [Fix] (All) RbScript: Comments no longer confuse the line counter; line numbers reported in CompileError events are thus less likely to be erroneous. [Fix] (All) RbScript: compiler no longer crashes when you try to pass a literal as a byref parameter. [Fix] (Mac) Editfield: Fixed a leak in the Editfield. [Kis] (All) Some circumstances can cause a delay when selecting rows in a listbox. Syptoms may include incorrect row selection if mouse is moved rapidly. 4.0fc1 -- 2001/12/17 [Chg] (Car) Unicode Editing: No longer test some assertions in AtsuEdit.cpp. [Fix] (All) Listbox: Editable cells no longer jump a pixel to the right when the cell gets the focus. [Fix] (All) Listbox: Editable cells now scroll properly with the listbox. [Fix] (All) Listbox: Editable cells now come into view if the user types in the cell. [Fix] (Mac) RbScript: memory is no longer corrupted when source property is changed. [Fix] (Mac) RbScript: now initializes temporary storage space, which fixes a memory corruption bug. [Fix] (Mac) TabPanel: Controls on a tabPanel no longer cause problems on OS 8.0 and 8.1. 4.0b5 -- 2001/12/16 [Fix] (Mac) File dialogs: drawing of contents from other windows into these dialogs has been fixed. [Fix] (Mac) Listbox: The selected row now moves when the listbox is sorted. This fix only applies to listboxes with single selection specified. This is still an issue with listboxes with multiple selection specified. [Fix] (Mac) Modal dialogs: now properly re-activate when you switch out to another app and then switch back by clicking in the dialog content area. [Fix] (Mac) MultiLine Editor: Added space between buttons to accomodate OS X. [Fix] (Mac) Properties Window: Fixed Big Ugly Button that used to pop-up occasionally in the properties window, especially on OS X. [Fix] (Mac) RbScript: PartialRun works again [broken with introduction of native code compiler] [Fix] (All) RbScript: State property is now updated when a script finishes running. [Fix] (Car) RbScript: assertion failure at CGPPC.cpp:786 no longer occurs. 4.0b4 -- 2001/12/13 [New] (Car) EditField: Unicode input is now supported. This allows you to use key layouts such as "Extended Roman." However, this works only in built apps, not within the IDE. [Fix] (All) Dictionary: freeze when adding more than 32746 items has been fixed. [Fix] (Mac) EditField: multi-line EditFields with a horizontal scrollbar on classic MacOS no longer have strange selection-drawing behavior. [Fix] (Mac) EditField: MouseDown event can no longer disrupt the display of the field if you do something that changes the graphics state, such as assigning to a StaticText. [Kis] (Mac) EditField: MouseDown event -- returning true from this event does not actually stop the EditField from processing the click, as it does under Carbon. This will probably change in the future. [Fix] (Car) EditField: flicker that appears while typing in a Carbon app under classic MacOS has been reduced. [Fix] (Car) EditField: selection point is now at start rather than end of text when a field first opens, or after assigning to the Text property, or using SetTextAndStyle. [Fix] (Car) EditField: now behaves more like the Classic EditField if you do something nutty like change the selStart property in the SelChange event. [Fix] (Car) EditField: dragging text over a field, but then dropping it elsewhere, no longer leaves behind a visual indication of the last potential drop position. [Fix] (Win) EditField.SetTextAndStyle: no longer causes strange redraw problems. [Fix] (OSX) External Project Items: crash that could occur when control-clicking an external item (such as a picture) whose external file can't be found. [Fix] (Mac) Listbox: Calling GetPixel/SetPixel in the CellBackgroundPaint or CellTextPaint events will no longer cause an outofbounds exception in cases where the cell is partly scrolled offscreen. GetPixel will return a white pixel and set pixel will be ignored. [Fix] (All) Listbox: When entering a cell for the purposes of editing by either clicking in an editable cell or using the editCell method, the entire text is now selected, instead of some of it. This selection also now occurs before the CellGotFocus so you can change it in that event if desired. [Fix] (All) Listbox: Editable cells now clip to the bounds of the listbox again. [Fix] (IDE) New Project: now always considered unmodified, even after declining to save the last project. [Fix] (IDE) PopupMenu: baseline alignment has been corrected; previously off by 1 pixel. [Fix] (IDE) Project: importing a class that replaces an existing class of the same name now updates all controls and subclasses of that class, so you should immediately be able to run. [Fix] (All) RbScript: fixed some problems with variant type conversions. [Fix] (Win) Shell: fixed possible memory corruption when retrieving the result string. [Fix] (Mac) Socket: Fixed memory leak caused by connecting before the previous connect request finished. [Fix] (Mac) Socket: Attempts to connect to the same address and port of a socket are ignored if the connection is already in progress, this makes it possible to call connect in a timer. If you want to start a new connection, close the connection first and then call connect, or change the address and port. [Fix] (Win) UnhandledException event on Application class catches otherwise unhandled exceptions. The event can return True if it handles the event and False if it wants REALbasic's default unhandled exception processing to occur. 4.0b3 -- 2001/12/11 [New] (Car) EditField: copy/paste now supports Unicode (UTF-16) data (standard Mac type 'utxt'). [New] (All) RbScript: new array method "Pop" removes the last element of the array and returns its value. [New] (All) RbScript: now supports second parameter for the Ubound function, as in REALbasic itself. [New] (All) RbScript: now catches nil object exceptions instead of allowing the script to crash. [Fix] (IDE) 68k: Fixes a problem that could occur when your project had specified using 68k and 68k only. [Fix] (IDE) Build Settings Dialog: If you inadvertently type a smaller suggested size than minimum size, REALbasic will up your suggested size to the minimum value. [Fix] (IDE) Build Settings Dialog: REALbasic now warns you if you have 2 or more application with the same name, specified in the build dialog and won't let you dismiss the dialog until you fix them. [Fix] (IDE) Compiling: assertion failure at "compile.cpp:7071" has been fixed. [Fix] (OSX) Listbox: Non-Hierarchical listboxes on OS X no longer highlight the cell text. A row highlight is still performed but can be overridden by code in the CellBackgroundPaint as always. [Fix] (Mac) Listbox: Listbox Headers now auto-deactivate when the REALbasic app goes into the background. [Fix] (OSX) Listbox: A ColumnSortDirection of 0 (Don't sort) will no longer show the sort widget in the header even if you are currently depressing the header. [Fix] (All) Listbox: CellClick event now returns the correct x value and not the correct value + 1. [Fix] (All) Listbox: Rowpictures moved down a pixel to behave more like they did in 3.5. [Fix] (All) PopupMenu.RowTag: a nilobject exception is now raised when converting a non-existent rowtag value. [Fix] (IDE) Project Window: "New Subclass" contextual menu command has returned for class items. (Disappeared in 4.0a5.) [Fix] (PPC) RbScript: objects no longer get unlocked twice (this sometimes led to crashes). [Fix] (All) RbScript: no longer allows you to ignore function results. [Fix] (All) RbScript: Spurious type mismatch errors when passing a reference variable or object property to a method have been suppressed. [Fix] (All) RbScript: peculiar string behaviour, sometimes resulting in crashes, has been corrected. [Fix] (All) RbScript: arrays of objects no longer cause massive memory leaks. [Fix] (All) RbScript: ReDim'ing an array of strings no longer causes occasional crashes. [Fix] (Win) Strings: comparing an empty string with a string with null character(s) now works like it does on the Mac. [Fix] (OSX) TabPanel: now draws with surrounding area properly matched to the background. Also, most controls draw properly on top of the TabPanel, but see [Kis] below. [Chg] (All) Control hierarchy: removed control hierarchy behaviour. Controls now behaves like they did before 4b1. [Kis] (OSX) LittleArrows, ChasingArrows: don't properly draw on top of a tab panel if the window has a solid background color. [Kis] (All) TabPanels: embedding tabpanels is not possible. 4.0b2 -- 2001/12/07 [New] (IDE) Copying a control now copies all its embedded controls as well, same with cutting, all embedded controls are also cut. [Fix] (IDE) Build Settings: The non-release field is now larger so that you can type more than 1 digit. [Fix] (IDE) Build Settings Dialog: Macintosh Application name fields never inappropriately enabled. [Fix] (IDE) External Windows, Classes, and Modules: now written to (and read from) XML-format project files. Previously they were omitted from XML files. [Fix] (IDE) Listbox: Focus Rings no longer appear in the Window Editor around listboxes. [Fix] (IDE) Menu Editor: modifier keys (shift, command, option, and control) are now drawn properly in the menu display; the command-key glyph also now draws correctly in localized builds of the IDE (e.g., Japanese). [Fix] (IDE) Option dragging of multiple selected controls now fixed. [Fix] (IDE) Quit and Hide commands (in OS X): now properly localizable. [Fix] (All) Database -- REALdb: fixed a potential crash when selecting from an empty table (i.e. no records). [Fix] (All) Listbox: REALbasic no longer will attempt to draw the text of a listbox cell if there is none. This fixes a problem manifest when using a large RowPicture and no text on OS X, and will improve performance On Cells that don't have text. NOTE: The CellTextPaint event will still fires and behaves exactly as it used to. [Fix] (All) Listbox CellBorders: Improved drawing when 2 listbox cells have borders of differing types. [Fix] (All) Listbox CellBorders: Improved the look of borders surrounding one cell in a listbox. [Fix] (All) Listbox Editable Cell: Now honors the current font size when editing a cell. [Fix] (All) Listbox Editable Cell: Focus rings around cells look much better. [Fix] (All) RegEx: Now only matches and replaces the empty string once (and only once) in a Replace call where ReplaceAllMatches is set. technically, if we allowed it, the Replace should go on forever, but this does no good to anyone. The new behavior is more in line with what one would expect (i.e. it doesn't hang your machine). Here is an example of how to cause this. Set "$" to the search pattern and "a" as the replacement pattern. Since "$" matches the end of the string, it will always match so ReplaceAll didn't know when to terminate, now we terminate after replacing one empty string. Note: If a user implements their own "Replace All" based on successive calls to Replace they are responsible for seeing to it that they don't loop infinitely in this case. [Fix] (IDE) SpriteSurface: fixed spritesurface crash on close. [Fix] (All) TabPanels: it is now possible to embed TabPanels within TabPanels. [Fix] (Mac) FolderItem.OpenAsPicture: 8-bit images in formats other than PICT are now read with the correct color palette (PICT files were always read correctly). [Fix] (Mac) Timer: Macs that have been up more than 25 days no longer cause Timers to fail to start. [Fix] (Mac) UnicodeConverter library: now weak-linked, so you should be able to once again launch REALbasic even with extensions off. [Fix] (Car) EditField: Input Manager inline input now draws underline to show the input state. [Fix] (Car) EditField: Alignment <> 0 now behaves better on fields with a horizontal scrollbar. [Fix] (Car) EditField: dropping text into a field now fires the TextChange event. [Fix] (Car) EditField: now shows inactive/disabled state by "graying out" the text. [Fix] (Car) TabPanel: a control that is on top of another control that is on a tabpanel now properly draws the background color to match the tabpanel. [Fix] (OSX) Graphics.DrawString: Malloc warnings no longer appear in the Console when drawing characters with ASCII values less than 32. Also fixes a memory leak caused by such drawing. [Fix] (OSX) Listbox Headers: Headers now get a depressed look on OS X when appropriate. [Fix] (OSX) Listbox Headers: No longer draws the dark grey line underneath the listbox headers. The line is a holdover from very early prerelease version of OS X. [Chg] (IDE) Code Browser: Events in left pane of the Code Browser are now sorted alphabetically. The event that appears initially when editing may no longer be the first item on the list. We have changed the initial event of a few controls to better suit how people are likely to work. This won't affect your code. [Chg] (Mac) EditField: new ATSUI-based EditField is now used only in Carbon; classic builds now revert to the same technology (TextEdit and WASTE) used in 3.5 and earlier versions of RB. 4.0b1 -- 2001/12/04 [New] (IDE) Build Settings Dialog: Added a new field to specify the Mac OS X/Carbon name. This new field is also accessible using Applescript via the new buildMacCarbonName property of the class document in the standard suite. [New] (IDE) Build Settings Dialog: Added new menu option "Build Application..." that builds without hassling you with the dialog. To show the dialog the old menu option has been renamed "Build Settings..." you can now dismiss this dialog without building for your convience. The Build process is still AppleScriptable and Recordable. [Chg] (IDE) Built Application Name: The default built application name has been changed from "AppName", to some variant of "My Application". [New] (IDE) Make Application: when successful, the newly-created application(s) is (are) revealed and selected in the Finder. [New] (IDE) Control-C: now halts an app running within the IDE even when no code is executing. [New] (IDE) Find And Replace: The state of the Advanced options is now saved. [New] (All) Listbox: Added a sort method. This resorts the data based on the current HeadingIndex and ColumnSortDirection. Although HeadingIndex will also do this, we strongly encourage you to use the new function. HeadingIndex will most likely be deprecated in the next major revision of REALbasic. [New] (IDE) Preferences: added font size of 0 to the default control font size popup. [Fix] (All) Array.Insert: now works correctly for arrays of type Single; previously inserted garbage. [Fix] (All) Array.Insert: now works correctly for the boundary case when the insertion position is equal to the array's UBound()+1; in this case, it's equivalent to array.Append. [Fix] (Win) Controls: font size of 0 will now default to 12 on Windows. [Fix] (IDE) Compiler: now catches as an error cases like "me.someControl" or "someControl.someOtherControl", with the error message "Controls can't be accessed by name via other controls". Previously such cases would crash or cause other run-time errors. [Fix] (Mac) Database -- OpenBase plugin: No longer reports a "Cannot update cursor unless query includes _rowid field" when performing a selection or moving next. [Fix] (Mac) EditField: caret position in an empty paragraph is now more correct, even when the field alignment is set to 2 (centered) or 3 (right-justified), or at large font sizes. [1/2 hour] [Fix] (OSX) EditField: periods and spaces no longer trail to the right of a right-aligned field, causing the whole field to shift to the left. [Fix] (Mac) EditField: Focus ring now draws properly for EditFields which were previously hidden by a TabPanel or by Visible=false, and then shown. [Fix] (IDE) External Project Items: opening a project containing external items no longer causes REALbasic to unexpectedly quit under OS X. [Fix] (IDE) Find & Replace: ReplaceAll no longer causes infinite recursion when the item you are replacing is a subset of the replacement text and the user has successfully completed a find previously. Fixed part of the problem in 4.0a6. [Fix] (All) Listbox ColumnSortDirection: Setting the ColumnSortDirection from code works in many cases where it previously didn't. Namely: When the header of the column being set isn't currently depressed, When the value is 0 (Don't Sort) on an initial run, and From within SortColumn (Although not recommended). [Fix] (All) Listbox: CellLostFocus Event now fires whenever editing is committed or canceled even in cases where a forced commit or cancel occurs (e.g. DeleteAllRows). This fixes a failed assertion. [Fix] (All) Listbox: Sorting a listbox no longer messes up CellBorder information. [Fix] (IDE) Picture Project Items: if the picture file can't be found, RB will only ask you to locate it once (even if you cancel). But you can control-click it to Relocate it later. [Fix] (Car) Navigation Services: Fixed crash caused by dragging from a Finder Pop-up Window proxy Icon into a Nav Services window on Carbon. [Fix] (All) PopupMenu: MouseDown event no longer fires if clicking on a disabled PopupMenu. [Fix] (All) ScrollBars: MouseDown event no longer fires if clicking on a disabled ScrollBar. [Fix] (All) Sliders: MouseDown event no longer fires if clicking on a disabled Slider. [Fix] (All) RbScript: a bug where objects that implemented no interfaces would occasionally set themselves equal to nil has been quashed (introduced in 4.0a6) [Fix] (All) RegEx: You can now use Replace when the TargetString contains null characters. (Fixed half of this problem for version 4.0a6) [Fix] (OSX) StaticText, EditField: fixed an infinite loop (program hang) that could occur in the IDE when setting the width of the control to less than the width of some character it contains. [Fix] (Mac) Windows: refresh bug which sometimes caused windows (e.g. the toolbar) to stop drawing part of their content has now been fixed. [Chg] (Mac) EditField: border area is now erased only under OS X, and only when there is a border. This allows for a better appearance over colored backgrounds that don't match the window background color, under classic MacOS or when using borderless EditFields. [Chg] (All) EditField: removed Boolean result in MouseUp event. [Chg] (All) Listbox: Sort Widget no longer appears when there is no space to draw it. [Chg] (OSX) Listbox: Sort Widget no longer appears (on Mac OS X) when the user has Don't Sort selected. [Chg] (OSX) Listbox: Text is no longer white (On Mac OS X) when the user is depressing the header. [Chg] (All) Listbox: Text now doesn't overwrite its borders in the header if it is too large to fit. [Chg] (All) Listbox: ColumnSortDirection will no longer sort the data. To explicitly sort the data after calling ColumSortDirection we suggest you use the new Sort function although calling HeadingIndex will also work. [Chg] (All) Listbox: HeadingIndex no longer will re-depress the bevel button of the listbox. this has the desired side effect of making it so that the columnSortDirection won't change if the user writes code like this listbox1.headingIndex = listbox1.headingIndex. Although this will work we suggest you use listbox1.sort instead of the above. [Chg] (IDE) Scripting REALbasic: It is no longer possible to build a 68k target with REALbasic. You will need to wrap the relevant code in a try block. [Chg] (Mac) Stack Size: increased from 24K to 256K. This allows recursion to proceed 10 to 20 times more deeply before causing a StackOverflowException. 4.0a6 -- 2001/11/21 [New] (Mac) AppleEvent.Ptr and ReplyPtr: these two new integer properties provide pointers to the underlying AppleEvent data structures, for use with Declares. [New] (All) Editfield: added paragraph alignment, via the following new properties: Alignment (integer) -- controls alignment/justification of the entire EditField. SelAlignment (integer) -- controls alignment/justification of the selected text -- or more accurately, the paragraphs that include any or all of the selected text. Values for both properties will be as follows: 0: default alignment; 1: left justified; 2: centered; 3: right justified; -1: mixed, used as the value of SelAlignment when the selection spans multiple paragraphs which have different alignment (Note: alignment for single-line EditFields works only on Win2000/XP, or on MacOS where ATSUI is available. To achieve the same effect on older systems, use a multiline editfield without a vertical scrollbar. Then handle the enter/return key to prevent the user from going to the next line.) [New] (All) EditField: added horizontal scrollbar, and ScrollPositionX properties. ScrollBarHorizontal (boolean) -- determines whether or not the editfield will have a horizontal scrollbar. If true, then the text does not word wrap. (Note: this property cannot be set at runtime). ScrollPositionX (integer) -- scrolls horizontally to a point (in pixels) in the editfield. (Note: on Windows, ScrollPositionX only works for Win2000/XP; on MacOS, it works only for systems with ATSUI, or for multi-line EditFields.) [New] (Mac) EditField.StyledTextPrinter: available once again. [Kis] (Mac) EditField.StyledTextPrinter: bold text sometimes fails to draw on some versions of MacOS. This appears to be an Apple bug, and we're currently looking for a work-around. [New] (All) Editfield: ScrollBar property renamed to ScrollBarVertical. [Dep] (All) Editfield: ScrollBar property now deprecated. [New] (All) Listbox: Added triangular sorting widgets to the headers of listboxes. Headers default to the ascending sort widget. Clicking on a header that is already depressed will switch the widget from ascending to descending or descending to ascending. It will also resort the data accordingly. If you use the CompareRows event it will automatically handle any sort direction changes. If you use the ResortColumns you are responsible for handling it when the user switches sort directions. To get/set the sort direction manually use the following method "ColumnsortDirection(column as integer)". Valid sort directions are as follows. -1 = descending, 0 = don't sort, 1 = ascending (default). Don't sort won't sort your data, and it won't call your Resort, or CompareRows events either. If you specify don't sort the user can't change the value of the sort widget by clicking on it. The sort direction can be set even when there is no header present. [Kis] (OSX) Listbox SortWidget: OS X doesn't provide a way to make a listbox header appear without a sort widget. Using Don't sort on OS X, works functionally but will display the descending sort widget. [Kis] (All) Listbox SortWidget: If there isn't enough room for your text and the sort widget the widget and the text will overlap. [New] (Mac) Listbox: When both horizontal and vertical scrollbars are used, the "dead space" in the lower-right corner is now filled with the proper appearance (when running on Macs with Appearance Manager 1.1 or later). [New] (All) RbScript: classes can now declare new events using a New Event declaration [New] (All) RbScript: Methods can handle events using the "Handles Event" declaration. [New] (All) Shell: New events and properties allow interactive use of a shell session. [New] (Mac) System.KeyScript: this new integer property allows you to get and set the keyboard script. The values are script systems, e.g. 0 for MacRoman, 1 for MacJapanese, etc. In addition, you can assign negative numbers to get various special effects, e.g., assign -1 to switch to the next layout in the Keyboard menu. For more info see: <http://developer.apple.com/techpubs/mac/Text/Text-386.html> [Chg] (All) Database -- REALdb: trailing semi-colons are now ignored when performing a SQL Select or Execute statement. [Chg] (All) Database -- 4D: trailing semi-colons are now ignored when performing a SQL Select or Execute statement. [Opt] (Mac) EditField: performance on large amounts of text has been substantially improved. [Chg] (IDE) Find & Replace: "Include In Search" and "Where to Search" switched to better match workflow. [Chg] (IDE) Build Dialog: Build Option for 68k has been removed. [Chg] (All) SpriteSurface: order of events within a frame has been changed for improved convenience. On each frame, we now (1) call NextFrame; (2) check for collisions; (3) update the screen. [Fix] (Win) BevelButton: the background now shows through when placed on a tabpanel. [Fix] (Win) Checkbox, RadioButton: the background now shows through when placed on a tabpanel. [Fix] (Mac) EditField.Bold, Italic, Underline: setting these properties in the IDE once again has the intended effect on the initial style of the field. [Fix] (IDE) External Project Items: changes to properties, constants, New Events, etc. now cause external items to be marked for saving to disk. Also, these changes are disallowed if the external item is locked in the Finder. [Fix] (IDE) External Project Items: modules which are stored externally can now access their properties in built apps without causing a NilObjectException. [Fix] (IDE) Find & Replace: ReplaceAll no longer causes infinite recursion when the item you are replacing is a subset of the replacement text. e.g. "Bana" -> "AppleBanana" (broken for Current Method Scope in 4.0a5) [Fix] (IDE) Find & Replace: ReplaceAll now replaces all occurences of the found item in the Current Selection Scope and the Current Method scope even when the item is on the last line of the search. [Fix] (IDE) Find & Replace: Advanced options hidden by default. [Fix] (IDE) Find & Replace: "Include In Search" checkboxes now turn off when disabled to more accurately reflect what will actually happen in your search. [Fix] (Car) FolderItem.DisplayName: no longer crashes in a Carbon app running on MacOS 8 or 9. [Fix] (Mac) Listbox: Fixed a memory leak that occurred when drawing a disclosure triangle or a checkbox. [Fix] (All) Listbox: 0 width (or invisible) columns no longer are visible when they come after the last visible column in the listbox. [Fix] (Win) OpenAsPicture: had trouble opening pictures depending on the bit depth of the picture. Was broken in 4.0a4. [Fix] (All) PopupMenu: MouseDown now fires if PopupMenu has no rows. Also, returning True from MouseDown now stops the menu from displaying. [Fix] (Win) ProgressBar: indeterminant progressbars no longer flicker through tabpanels. [Fix] (All) RbScript: classes which inherit interfaces and declare properties no longer cause crashes when cast to one of the inherited interfaces. [Fix] (All) RbScript: overloading no longer breaks when assigning to a method. [Fix] (All) RegEx: You can now use Replace when the TargetString contains null characters. [Fix] (All) RegEx: You can now use null characters in the ReplacementPattern. [Chg] (All) RegEx: Using a null character in SearchPattern will result in a SearchPattern exception. If you want to search for null character use \x00 instead. [Fix] (Mac) UnhandledException event no longer intercepts EndExceptions in built applications. 4.0a5 -- 2001/11/09 [New] (All) EditField.CharPosAtXY: returns the position (1-based) of the character at pixel coordinates X,Y (relative to the EditField). I.e., the character at position x,y is the 7th chatacter in the editfield. [New] (All) EditField.InsertionPosAtXY: returns the position (0-based) of the insertion point closest to pixel coordinates X,Y (relative to the EditField). [New] (All) Listbox: CompareRows event added -- useful for creating custom sorts in a listbox. See the CompareRows read me. [New] (All) Listbox: MouseDown, MouseDrag and MouseUp events added. Returning true in MouseDown causes the MouseDrag and MouseUp events to fire and the default listbox click processing not to fire. [New] (All) RbScript: "Object" may be used with IsA; it will return true for any non-null object. Any object may be assigned to a reference of type Object. [New] (All) RbScript: interfaces supported, declared via Interface...End Interface structure. See RbScript Interfaces read me. [New] (All) RbScript: typecasting supported. Use the desired type's name as a function whose single argument is the object reference you want to cast. It will either succeed or report an IllegalExceptionError. [New] (IDE) Find And Replace: Control names -- results are revealed in the code browser. NOTE: None of the new options allow replacing. [New] (IDE) Find And Replace: Declarations -- Menu Handlers, User Property Declarations, and Method Declarations including parameters and reveals them in the Code Browser. [New] (IDE) Find And Replace: Project Items names -- including Classes, Windows, folders, resources, pictures, and so on. NOTE: None of the new options allow replacing. [New] (IDE) Find And Replace: Property Values: NOT IMPLEMENTED YET! [New] (IDE) Find And Replace: searches current selection in code editor. You can now search, replace and most importantly replace all within the current selection. [New] (IDE) Project Window: "New Subclass" contextual menu command creates a new subclass of the selected class. [New] (IDE) Super property: editfield with autocompletion and a hierarchical pop-up menu replace the old linear pop-up menu for setting the super of a class. [New] (IDE) Toolbar: dragging from the toolbar to the Project window now creates a new subclass of the dragged control. [New] (Mac) EditField.SelBold, SelTextColor, etc.: SelLength is zero now works. [New] (Mac) EditField: Home, End, Page Up/Down, and forward-Delete keys now work. [Opt] (Mac) EditField: adding text to an editfield in a loop is faster. [Fix] (All) color properties: Hue, Saturation, and Value color properties no longer return incorrect values when hues re in the range 0 through 0.166667 (0 through 60 degrees). This broke in 4.0a3 for Mac OS and has always been broken for Windows. [Fix] (All) Dictionary: Remove method no longer remove too much. [Fix] (All) Variants: assigning a variant to a local Color variable no longer causes an "internal compiler error." [Fix] (Car) Floating Windows: MacProcID values not normally associated with floating windows no longer prevent the window from floating properlysuch as 1040, an unadorned window). [Fix] (IDE) Arrays: NewProperty -- empty array properties, (i.e. with Bounds of -1). [4.0a4] [Fix] (IDE) Debugger: Exceptions no longer reported in the wrong place (broken in 4.0a4). [Fix] (IDE) Find And Replace: searches current selection in the project window if a code browser window is not open. NOTE: None of the new options allow replacing. [Fix] (IDE) Find And Replace: wrapping in current source -- the find will start at the current selection search downwards and wrap to search again at the top when it reaches the bottom. NOTE: None of the new options allow replacing. [Fix] (IDE) Listbox: Disclosure Triangles now highlight again when clicked upon if no CellBackgroundPaint is specified. Allowing this with CellBackgroundPaint would unfortunately draw a grey background behind the triangle which will most likely not match your background, so we decided to turn highlighting off in this case. It may be possible for us to work around this issue in some future release of REALbasic. [Fix] (IDE) Quitting a run within the IDE: CancelClose event errors no longer cause attempts to quit subsequent runs to be ignored. [Fix] (Mac) Code Browser: entering code in an item flickers less (updating an element name from plain to bold when a user enters code into the browser). [Fix] (Mac) EditField.BackgroundColor: EditField redraws itself when this property is changed. [Fix] (Mac) EditField.CharPosAtLineNum: returns correct values. [Fix] (Mac) EditField: caret (blinking cursor) size in a field containing no text is now a better approximation of what it will be when text is inserted. [Fix] (Mac) EditField: single-line EditFields no longer show the selection in outline mode when they don't have the keyboard focus (multi-line EditFields continue to do so). [Fix] (Mac) EditField:SelText: scrolls the cursor into view. [Fix] (Mac) Listbox: flickering reduced of listboxes on TabPanels in cases where the arrow keys are used to scroll the contents or the contents are drag scrolled. [Fix] (Mac) Listbox: memory leak when redrawing fixed. [Fix] (Win) ProgressBar: indeterminant progressbars no longer show through all tabs. [Tip] (All) Listbox: CompareRows -- A good strategy for sorting Dates would be to store the Date's total seconds property in a 0 width column in your listbox (BTW -- never use columns beyond the columncount) and when the CompareRow event fires for your date column sort based on the total seconds column instead. 4.0a4 -- 2001/11/02 [New] (All) Application.BalloonHelpVisible: BalloonHelp is disabled when set to false and enabled when set to true. Note: supported on Windows only. [New] (All) Dictionary class: stores one-to-one mappings of keys to values. Both keys and values may be any datatype. Optimized for rapid look-up of values regardless of the number of items it contains (look-up time is approximately constant). [New] (All) Function: DocumentsFolder -- returns a folderitem that represents the user's Documents folder. [New] (All) KeyNotFoundException: exception type added. Raised when attempting to access a Dictionary entry with a key that the Dictionary does not contain. [New] (All) Listbox: EditCell: will scroll the cell into view when EditCell is called when the cell is not completely visible. It performs the scroll in the most minimal way possible. E.g. if the cell is to the right of the listbox or is overlapping its right border, the cell will be scrolled such that its right border is flush with the list's right border. [New] (All) OutOfMemoryException: exception type added. Raised in certain cases when an operation cannot be completed due to insufficient memory. [New] (All) Picture: HorizontalResolution and VerticalResolution properties added. OpenAsPicture sets them, and SaveAsPicture or ExportPicture writes them. Default resolution is 72 for creating a new picture. [New] (All) Sound: Pan property added -- specifies the relative volume of the right and left channels within the range from -100 to 100. A value of -100 mutes the right channel, and a value of 100 mutes the left channel. Default 0. [New] (All) Sound: Volume property added -- specifies the output volume for the current sound as a percentage. Setting volume to 0 mutes the sound, while setting volume to 100 plays the sound with "normal volume" (ie. your current sound settings for your computer). Default 100. [New] (All) Variant: now has a number of new convenience methods and properties: IntegerValue: returns the value of the variant as an integer. ColorValue: returns the value of the variant as a color. DoubleValue: returns the value of the variant as a double. ObjectValue: returns the value of the variant as an object. StringValue: returns the value of the variant as a string. BooleanValue: returns the value of the variant as a boolean. Type as Integer: v.Type is equivalent to VarType(v) IsNumeric as Boolean: equivalent to IsNumeric(v) IsNull as Boolean: equivalent to IsNull(v) Hash as Integer: returns a hash value for the variant, i.e., one that will always be the same for any variant with that same value Equals(v2 as Variant) as Variant: returns true if v2 is the same type and has the same value as this one. [New] (All) Variants: color values can now be stored in variants; their VarType is 16. [New] (IDE) File Types: REALdb is now included in the file types popupmenu list. [New] (IDE) Tips window: method help for overloaded subroutines now shows parameters in parentheses, which is the syntax required by the compiler. [New] (Mac) EditField: Drag & drop is now supported. [New] (Mac) EditField: SelCondense and SelExtend now work; these styles are also supported when set via style data or loaded from a styled text file. [New] (Mac) EditField: styled copy/paste is now supported (for styled EditFields). [New] (Mac) EditField: TextStyleData property now supported, as is SetTextAndStyle. [New] (Mac) FolderItem: SaveStyledEditField and OpenStyledEditField now work. [New] (Mac) UnhandledException event -- catches otherwise unhandled exceptions on Application class. The event can return True if it handles the event and False if it wants REALbasic's default unhandled exception processing to occur. (Not yet implemented on Windows.) [New] (OSX) Serial Ports: available to Carbon apps running in Mac OS X. This includes the Serial Control, SerialPort class, System.SerialPortCount, and System.SerialPort. Note that Carbon apps running under MacOS 8-9 cannot access serial ports; for those systems, build a Classic PowerPC app instead. [Opt] (IDE) Code Editor: multiple uses of Delete (or forward-delete) are now combined into one action in the undo/redo queue. Also improves editor performance under OS X.[Chg] (All) DataControl: data bound controls -- disabled when the ReadOnly property is set to true (or read only in the case of EditFields). [Chg] (All) IsA method and typecasting: now report that all classes derive ultimately from Object. For example, x IsA Object returns true for any object x, and "o = someVariant" works when o is declared as type Object (and the variant contains any object). [Chg] (All) VarType: VarType of a variant containing an object is now 9 rather than 13, to better match the corresponding value in Visual Basic. [Chg] (Win) MDI application: now fires the quit menu handler when the MDI parent window is closed. Event hierarchy for closing an MDI parent window now looks like this: Quit menu handler (BRAND NEW!!!) CancelClose (for each MDI child window) Application Close Close (for each MDI child window) [Fix] (All) Control.Close: visual controls are now hidden before being deleted. [Fix] (All) Database.SQLSelect: no longer crashes after 3 or more selections are done, this also affected the DataControl. Was introduced in 4.0a3. [Fix] (All) Database: PostgreSQL plug-in -- updating a record (using Cursor.Update) which contain null fields now works. [Fix] (All) EditField: MouseDown and MouseUp -- events are now called appropriately. Note that returning true from MouseDown prevents the EditField from handling the click. [Fix] (All) Listbox: datasource can now be set in code. Note that this parameter takes a string argument. i.e. Listbox.DataSource = DataControl.Name [Fix] (All) Listbox: Editable Cells can now be clicked in again without the text disappearing off to the left. [Fix] (All) Listbox: Scrollbar columnwidths are now calculated more accurately. This results in the last column not drawing beyond the listbox. This was especially noticable when the last column contained an editable cell, as it would partly overwrite the scrollbar. [Fix] (All) RbScript: Mid allows length parameter to be omitted, InStr allows start parameter to be omitted; these were broken in 4.0a2. [Fix] (All) UBound:bounds of a multi-dimensional boolean array now correctly returned. [Fix] (IDE) Controls: Copying a control from one window and pasting it to another window no longer crashes. Broken in 4.0a3. [Fix] (IDE) New Property/Edit Property Dialog: error message more approriate when attempting to add a property with no declaration. Properties with invalid declarations can no longer be added. e.g. "dim myProperty as integer" , "myProperty as" or "myproperty". [Fix] (Mac) Database: OpenBase plugin -- dates and timestamps now retrieved and inserted in the correct format. [Fix] (Mac) Database: OpenBase plugin -- now supports multiple cursors. [Fix] (Mac) EditField: GotFocus and LostFocus -- events are now called appropriately. [Fix] (Mac) EditField: incorrect word wrapping under classic MacOS has been fixed. [Fix] (Mac) EditField: mouse cursor is now updated appropriately. [Fix] (Mac) EditField: text position now matches that in 3.5 EditFields; this is especially noticeable, for example, in the Properties window. [Fix] (Mac) Listbox: ActiveCell property -- Fixed a problem where listboxes wouldn't dispose it. Introduced in 4.0a3 [Fix] (Mac) Listbox: CellGotFocus and CellLostFocus events now fire when moving between Listbox cells. [Fix] (Mac) Listbox: contents hidden from view -- fixed several related occurences of where this could occur. [Fix] (Mac) Listbox: focus rings displayed around the ActiveCell on all Mac configurations. [Fix] (Mac) Listbox: highlight of rows on non hierarchical listboxes no longer clipped just to the width of the columns. [Fix] (Mac) Listbox: multiple highlight no longer occurs on classic Mac listboxes that don't have double buffering. NOTE: double buffering is only turned off on the Mac when there isn't enough memory to double buffer the listbox. [Fix] (Mac) Listbox: NewPicture in a listbox's CellBackgroundPaint event or CellTextPaint events no longer confuses the origin of double buffered listboxes. [Fix] (Mac) Listbox: Row Pictures are now transparent again. [Fix] (Mac) RbScript: Format function no longer crashes (broken in 4.0a1). [Fix] (New) UBound: dimension parameter -- an optional second parameter "dimension" added. Gives the bounds of that dimension. When left unspecified UBound will give the bounds of the 1st dimension. If an invalid dimension is specified e.g. -4, 0, 5 (in a 4d array) UBound will throw an OutOfBoundsException. NOTE: Dimensions are counted upwards starting at 1. SPECIAL: if you pass -1 as the second parameter, UBound will give you the number of dimensions in the Array. [Fix] (Win) Listbox.KeyDown: now returns a valid key parameter. [Dep] (All) Collection class: Dictionary class should be used instead. Collection is useful mostly for conversion of VB projects. [Dep] (All) EditField: MouseUp -- return value of this event has no effect, and its use is deprecated. [Kis] (Mac) EditField: Shadow and Outline styles are not supported by the new EditField, and probably never will be; consider these styles deprecated. [Kis] (Win) Database: OpenBase plugin -- no Win32 target. [Kis] (Win) Sound: midi files do not allow the pan or volume properties to be set when playing. 4.0a3 -- 2001/10/24 [New] (All) Controls: Close method added for control classes. Closing a control permanently removes the object from memory, and it can no longer be accessed. You can close conventional controls, as well as those belonging to a control array. When closing indexed controls (i.e., control array controls), the indexes will shift accordingly to fill in the gaps. For example, if you delete index 0, index 1 becomes 0, index 2 becomes 1, etc... [New] (All) Database: 4D plug-in -- DatabaseCursor -- MovePrevious, MoveFirst, and MoveLast added. [New] (All) Database: REALbasic Database -- DatabaseCursor -- MovePrevious, MoveFirst, and MoveLast added. [New] (All) Graphics: StringHeight method Added. You pass it text and a wrapWidth, it returns the height of text as it would be drawn. [New] (All) Listbox: ActiveCell property added. This is the editfield that the listbox is using for its editable cell operations. You can use this property to set or get the text of the listbox (selText), set the selection, or change other properties of the listboxes editfield. NOTE: You can not currently set the ActiveCell so you will not be able to use a subclass editfield as a substitute. NOTE: We do not guarantee that all of the features of the editfield make sense to use in context of a listbox. [New] (All) Listbox: CellClick event added. It occurs when the user clicks the mouse on the cell of a listbox. The event will pass you the row and column of the cell clicked and the x, and y position of the click which are relative to the top left of the cell and correspond exactly with the bounds of the graphics property in the CellBackgroundPaint event. Returning true from this function will cause the event to not be processed further (this means that editable cells won't be editable and listbox selection won't change. [New] (All) Listbox: CellGotFocus event added. It occurs when a user enters an editable cell of a listbox. The event will pass you the row and column of the cell that just got the focus. [New] (All) Listbox: CellKeyDown event added. It occurs when the user presses a key on the keyboard whilst a listbox cell is currently being edited. The event will pass you the row and column of the cell being edited and the key pressed. returning true from this function will prevent the text from changing (at least automatically, you can do it yourself (see ActiveCell property), and keep the CellTextChange event from firing. [New] (All) Listbox: CellLostFocus event added. It occurs when a user leaves an editable cell of a listbox either by pressing return or esc, or by the user clicking on another cell. The event will pass you the row and column of the cell that just lost the focus. [New] (All) Listbox: CellTextChange event added. It occurs after the KeyDown event if keydown returns false. The event will pass you the row and column of the cell being edited. [New] (All) Listbox: EditCell method added. You pass it a row and column number. It will scroll the cell into view and temporarily change the cell to an editable cell, setting the focus in that cell. [New] (All) Picture: depth property added -- read-only. [New] (All) RbScript: "Inherits" declaration added to implement class inheritance. [New] (All) RbScript: Colors can now be constructed with the RGB, CMY, and HSV functions, and the usual color properties are available. [New] (All) RbScript: destructors supported.

[New] (All) TabPanel: MouseDown, MouseDrag and MouseUp events added. [New] (IDE) Database: Schema Editor View Data -- column names appear at the top of the View Data window. [New] (IDE) Database: Schema Editor View Data -- number of rows in the table now displayed in the title of the View Data window. [New] (IDE) Database: Schema Editor View Data -- scrolling vertically and horizontally in the View Data window allows you to see more of your data. [New] (IDE) External Project Items: windows, classes, and modules can now be stored and updated external to the project file. To do this, hold down Command+Option while dragging the item into a project file. It will be imported as a reference to the original file, rather than copying the data into the project. See the External Project Items Read Me for more details. [New] (IDE) Run command: Applescriptable/Recordable. [New] (IDE) Run command: changes to "Resume" while your application is running, to better reflect what it does and to act as an extra reminder that your app is already running. [New] (Mac) Listbox: Editable Cells now show a focus ring when the contents are being edited. [Chg] (All) DataControl: MovePrev method and event renamed to MovePrevious. [Chg] (All) Listbox: top and left of a listbox draw the default gridlines -- this affects how the text and other elements are centered in the cell, and can affect appearance of top and left of listbox with borders that are thicker than one pixel wide. [Chg] (All) StaticText: boolean result from MouseUp event removed. [Chg] (IDE) Table Schema Editor: primary key not being specified when creating a table causes an alert to appear. [Chg] (Win) EditField: single line editfields can now accept tabs. [Fix] (All) Database: PostgreSQL plugin -- getting the field schema values by field name now works. Example: schema.field("FieldType").getString [Fix] (All) Listbox: Horizontal scrolling code is no longer called twice resulting in better performance, and less flicker on Win32. [Fix] (All) Quit: calling in code and selecting from the menu now behaves consistently. [Fix] (All) RbScript: State property is now readable. [Fix] (All) Self.Close: no longer crashes when called from within an event from a plugin. Was broken in 4.0a2. [Fix] (All) Socket:running a second time, after the first run died due to an error or the Kill command, no longer crashes. [Fix] (IDE) Controls: duplicated custom controls no longer lose their super setting. [Fix] (IDE) Database: Schema Editor View Data -- works again (broken since 4.0a2). [Fix] (Mac) EditField: crash in new EditField caused by deleting a range of text that includes the selection has now been fixed. [Fix] (Mac) EditField: drag-selecting a large block of text no longer causes an assertion failure. [Fix] (Mac) Listbox: Checkboxes and disclosure triangles now draw within the bounds of the listbox. was broken in 4.0a1. [Fix] (Mac) Listbox: Disclosure Triangle of a hierarchical listbox no longer moves down a pixel when clicked on. [Fix] (Mac) Listbox: drawing origin of a listbox no longer gets corrupted when a user updates another control from within the CellBackgroundPaint or the CellTextPaint events. (4 alpha) [Fix] (Mac) Listbox: white line at the bottom of each row in a hierarchical listbox is now covered again by single line width borders. [Fix] (Mac) MacOS 8.1 (and earlier) compatibility: ATSUnicodeLib not being present no longer prevents launch. [Fix] (OSX) Bundle Information: UTF-8 encoding now properly implemented, which fixes problems with the application name as it appears in the menu bar where non-Roman characters are involved. [Fix] (OSX) Compiler:running your program in the IDE under Mac OS X (especially 10.1), or in classic Mac OS when the IDE's memory partition is set to 64MB or larger no longer crashes. [Fix] (Win) Listbox: text color set in the Windows Control Panels used for text color again. [Fix] (Win) Quit: calling Quit in code no longer finishes executing code in the method that was calling it. [Fix] (Win) Socket: destroying a socket no longer causes extraneous socket events to be fired. 4.0a2 -- 2001/10/08 [New] (All) Canvas: Focus and Key properties and events added. 3 new properties: UseFocusRing, AcceptFocus, and AcceptTabs and 3 new events:GotFocus, LostFocus, and KeyDown. See the New Canvas ReadMe for more details. [New] (All) Database: 4D Plugin -- blob comparison now works. [New] (All) Database: REALdb -- blob comparison now works. [New] (All) GroupBox: MouseDown, MouseDrag, and MouseUp events added. [New] (All) Line control: MouseDown, MouseDrag, and MouseUp events added. [New] (All) Listbox: CellBackgroundPaint event added. You can now paint to your hearts content here. If you don't return a value or you return false REALbasic will attempt to handle row highlighting, and column highlighting for you (where appropriate). If you return true, you can handle this yourself. [New] (All) Listbox: CellTextPaint event added. You are passed x and y which is ideal position to draw your original text based on the columnAlignment. You can draw the text yourself or you can change the state of the graphics object and have it draw it for you. (e.g. g.foreColor = RGB(255, 0, 0) will direct it do draw red text). REALbasic will attempt to perform appropriate CellHighlighting on hierarchical listboxes if you return false. If you return true you can handle this yourself. [New] (All) Listbox: DefaultRowHeight is a new property on the listbox which determines the height of every row of the listbox. To have the height determined automatically based on the font height chosen, set the DefaultRowHeight to -1. [New] (All) Oval control: MouseDown, MouseDrag, and MouseUp events added. [New] (All) ProgressBar: MouseDown, MouseDrag, and MouseUp events added. [New] (All) Rb3DSpace: fog support added through two new properties: FogVisible (Boolean) indicates whether fog should be drawn at all; FogStart (Integer) indicates how far away from the camera the fog should begin. The fog gets thicker from that point (or Hither, whichever is further away) until the Yon distance, where it is fully opaque. The fog color is the same as the SkyColor. [New] (All) RbScript: Class/End Class structure now supported -- used to define classes for use inside a script. Properties and methods are supported; inheritance and interfaces are not. [New] (All) Rectangle control: MouseDown, MouseDrag, and MouseUp events added. [New] (All) RoundRect control: MouseDown, MouseDrag, and MouseUp events added. [New] (IDE) Project Items: dragging a project item (such as an AppleScript) onto a button or into a code editor now inserts at least the name of that item. [New] (Mac) EditField: EditFields now use the new underlying technology (in MacOS 8.5 and later). It's still not quite done yet, but nearly so. [New] (Mac) EditField: Symbol font, as well as accented and other high-ASCII characters, are now supported by the new unstyled EditFields (in addition to other improvements too numerous to mention). [New] (Mac) File Name Extensions: Open dialogs -- filters files by extension if they have no type code set (as happens with some ill-behaved Mac OS X applications). In other words, a file will be available in an Open dialog if either its MacType matches the type you specified, or if its MacType is '????' or null but its extension matches one of the extensions you specified in the File Type settings. [New] (OSX) Control Captions: region codes other than that of the application now supported. Some OS controls (such as PushButton) can now show a caption that uses an encoding that doesn't match your application's region code (or while running within the IDE, the IDE's region code). For example, an English application can set a Japanese caption, as long as it first sets the button's TextFont to Osaka. (This has always worked in classic MacOS, but did not previously work in Mac OS X.). [New] (OSX) File Name Extensions: FolderItem.DisplayName -- property added which gives you the name of a file as it should be seen by the user. This property is read-only. The DisplayName is usually the same as FolderItem.Name, but under Mac OS 10.1, it may be the name without the extension, depending on whether the user has file extensions hidden for that particular file. [New] (OSX) File Name Extensions: FolderItem.ExtensionVisible -- property added which allows you to tell (or change) whether a given file has its file extension hidden or visible, or change that status. Currently applies only under Mac OS 10.1. Note that when you change this setting, the Finder or subsequent Navigation dialogs may not reflect the change right away. [New] (OSX) File Name Extensions: FolderItems -- creating a new file (e.g., via CreateAsTextFile) sets the "hide extension" flag according to the value of the ExtensionVisible property. [New] (OSX) File Name Extensions: GetSaveFolderItem and SaveAsDialog -- now present the Mac OS 10.1 user with a new "Hide Extension" checkbox, on by default. The FolderItem returned has its ExtensionVisible property set according to the user's use of this checkbox. [New] (OSX) FolderItem.Launch: behaves the same as double-clicking the item in the Finder. [New] (OSX) Progress Bars: larger appearance now supported when the height is set to 18 pixels or more. [New] (Win) Windows: MDIWindow class added to the application class. This class is used to control the behavior of the MDI window on Windows. See the MDI Window Class Read Me for more details. [Chg] (Car) File Name Extensions: Carbon built applications -- file extensions are now written to the 'plst' resource without the leading period, per Apple standards. [Chg] (IDE) File Name Extensions: Project Files -- now have ".rb" appended to the project name if not there already when doing a "Save As". Under versions of Mac OS prior to 10.1, you can easily change or remove this if you wish. Under 10.1 the extension may be hidden by default, depending on your system preferences. [Chg] (IDE) Interfaces: Adding new interfaces to the project previously resulted in a project entity named "Class1" or "Class2" etc. Now it results in a project item named "Interface1" or "Interface2" etc. [Fix] (All) CheckBox: datasource can now be set in code. Note that this parameter takes a string argument. i.e. CheckBox.DataSource = DataControl.Name [Fix] (All) Database: PostgreSQL Plugin -- error code is now initialized to 0 before connecting. [Fix] (All) Database: PostgreSQL plugin -- fieldschema now returns 5 columns instead of 6. [Fix] (All) Database: REALdb -- long varbinary column adding with Alter Table SQL statement now works. [Fix] (All) EditField: datasource can now be set in code. Note that this parameter takes a string argument. i.e. EditField.DataSource = DataControl.Name [Fix] (All) Listbox: CellBorders now form a rectangle around a cell (previously they would overlap into other cells and looked bad when applied to individual cells). [Fix] (All) Listbox: Cellborders/GridLines now center themselves between rows and columns so that the contents are more balanced. [Fix] (All) Listbox: Failed Assertion no longer occurs when removing a scrollbar in a Canvas's MouseUp event. [Fix] (All) Listbox: FocusRing now appears after refresh, and focusrings are moved properly when the control moves. [Fix] (All) Listbox: Hierarchical listboxes now highlight the item in the first column to be more consistent with the way highlighting is done in the Finder/Explorer. [Fix] (All) Listbox: Scrolling of invisible listboxes, or listboxes on an invisible tab of a tab panel, by setting the scrollPosition or the ScrollPositionX no longer result in unwanted portions of the listbox appearing. [Fix] (All) PopupMenu: datasource can now be set in code. Note that this parameter takes a string argument. i.e. PopupMenu.DataSource = DataControl.Name [Fix] (All) RbScript: disposes of temporary data structures after compiling, thus plugging a memory leak that occurred on every run or pre-compile. [Fix] (All) RbScript: For-Next loop allows floating-point loop counters and step values. [Fix] (All) RbScript: very large integer constants are automatically converted to double precision if they would have exceeded the upper limit of a 32-bit signed integer. [Fix] (All) Self.Close: no longer crashes when used inside an event such as MouseDown in a Canvas. [Fix] (All) StaticText: datasource can now be set in code. Note that this parameter takes a string argument. i.e. StaticText.DataSource = DataControl.Name [Fix] (IDE) File Types dialog: clicking the "OK" button now counts as changing the project, thus enabling it to be saved (or prompting you to save when you close the project). [Fix] (IDE) GetOpenFolderItem: Open event of the default window -- calling GetOpenFolderItem or using FolderItemDialog classes in the Open event of the Default window no longer crashes when called from when running within the IDE. [Fix] (IDE) Listbox: gridlines no longer appear when not required in some ListBoxes in the IDE. [Fix] (Mac) Listbox: editable cell's text is now visible again. [Fix] (Mac) Listbox: Listboxes on a tabPanel and listboxes in the CodeBrowser no longer flicker when scrolling. (Mac Only) [Fix] (Mac) Movies: FolderItem.OpenAsMovie -- QuickTime initializes if it hasn't already. Fixes a bug which caused this method to return nil in a built application unless something else (e.g., a Movie control) had already initialized QuickTime. [Fix] (Run) Listbox: no longer flickers when row is selected. (Mac Runtime only) [Fix] (Win) BalloonHelp: clearable when you already have a HelpTag set. [Fix] (Win) Byref: local variables are now initialized to 0 when passed byref. This fixes the problem with calling ParseDate without first creating a new date object, and passing strings byref without actually using the strings in your function. [Fix] (Win) Graphics: painting on a window while resizing no longer draws on the desktop. [Fix] (Win) Listbox: Cellborders and Gridlines now work for Win32. [Fix] (Win) Plug-in SDK: REALSetControlFocus function -- now fully clears the previous focus. [Fix] (Win) Resizing: resizing a window no longer causes horrible flicker. [Kis] (Mac) EditField: does not currently support CharPosAtLineNum, LineNumAtCharPos, ScrollPosition, TextStyleData, SetTextAndStyle, or StyledTextPrinter. (4.0a2) [Kis] (Mac) File Name Extensions: "Open" dialogs: there still is no way to enable selection of any (say) text file, without using a wildcard type to allow all files. If the file on disk does not have a type code set, and it's using an extension you didn't think of when you defined your File Type, then there is simply no way to know that it's a valid type of file. Please direct your feedback about this to Apple via their Mac OS X Feedback web page. [Tip] (IDE) Project Items: dragging Windows and Sounds to a button or code editor inserts WindowName.Show or SoundName.Play, respectively (using the actual name of the item, of course). [Tip] (OSX) File Name Extensions: To give the proper user experience under Mac OS X, here's what you should do: 1. Whenever displaying a file name to the user (e.g. as the title of a window), use f.DisplayName rather than f.Name. 2. Whenever interacting with the file system, use the true name (f.Name). 3. Leave the ExtensionVisible property alone in most cases. 4. Be sure to define extensions for all your document types. 4.0a1 -- 2001/09/24 [New] (All) Bin Function: converts a number into a string in binary format. See references for Oct and Hex for more detail on how this works. [New] (IDE) ListBox: Appearance in the Window Editor reflects more accurately the appearance in the running application (it's actually a real ListBox now). Specifically Hierarchical, GridLinesHorizontal, GridLinesVertical are now displayed in the ListBox, and changing the HeadingIndex will actually re-sort the ListBoxes contents in the Window Editor. [New] (All) ListBox: GridLines/CellBorders added to the ListBox. The properties are called GridLinesHorizontal and GridLinesVertical. You can also get/set CellBorders on cell-by-cell basis, the functions are called CellBorderTop(row, column), CellBorderLeft(row, column), CellBorderRight(row, column) and CellBorderBottom(row, column). You can set these to one of several styles (some of which don't work for Win32 yet). The styles are default = 0, none = 1, thinDotted = 2, ThinSolid = 3, ThickSolid = 4, DoubleThinSolid = 5. [New] (All) ListBox: HasHeading property can now be set at runtime (not just at compile time). [New] (All) ListBox: Hierarchical property can now be set at runtime (not just at compile time). [New] (All) Plug-in SDK: several new methods and enhancements have been added; see the SDK version history for details. [New] (All) RbScript: Parentheses are now allowed (but not required) on subroutine calls. [New] (IDE) Color palette: dragged colors now contain a text description, allowing you to drag from the color palette to the code editor, the desktop, or any text editor. [New] (IDE) Copy-click: floating palettes now supported. For example, hold the Option key and click on the name of a property in the Properties value, and that name will be inserted into the code editor as if you'd typed it. Also works for property values, colors in the Color palette, and tools in the Toolbar. [New] (IDE) Window Editor: contextual menu added which provides commands to close the window, switch to the code editor, select any control on the form, or add a new control based on any class. [New] (Mac) EditField: single-line unstyled EditFields in MacOS 8.6 and higher now use a completely different underlying technology. This brings benefits such as no 32K text limit and CoreGraphics font rendering in OS X. But they're still a work in progress -- see known issues below. [New] (Mac) ListBox: Smooth scrolling with virtually no flicker -- Now double buffered on the Macintosh. [New] (Mac) RbScript: compiles Scripts on PowerPC. Now compiled to machine language and executed as native code instead of running through an interpreter. [New] (Win) ListBox: Flickers less with horizontal scrolling on Windows. [Opt] (Mac) Plug-in controls: redraw only if something is refreshed within 4 pixels of the control bounds, instead of being redrawn whenever anything on the window is refreshed. (Plug-in authors should take care not to draw more than 4 pixels outside their control bounds.) [Fix] (All) DataControl: database property -- setting this in code no longer crashes. [Fix] (All) Plug-in controls: disabled controls no longer receive the focus. [Fix] (All) RbScript: Hex, binary, and octal constants now work without throwing assertions. [Fix] (IDE) App.Resources: running your application by choosing "Run" with the mouse instead of pressing command-R once again accessible. [Fix] (IDE) Compile Errors: Windows target returns an error when building an application that uses the ResourceFork. [Fix] (IDE) International: some data aware property strings can now be localized, as well as the binding strings as seen when selecting a bind from a dialog. [Fix] (IDE) Window menu: balloon help now correctly matches the menu commands. [Fix] (Mac) DrawInto: ListBoxes drawn via DrawInto now draw disclosure triangles, checkboxes, supports textSize, textFont and textStyle. ListBox headers are now properly clipped. [Fix] (Mac) ListBox: Hierarchical ListBoxes -- now draw the column highlight all the way to the left in Column 0 as the finder does. [Fix] (Mac) Plug-in controls: REALcontrolFocusRing flag is now observed; a control without this flag set will not have a focus ring drawn for it by REALbasic. [Fix] (Win) BevelButton: caption now aligns properly when it is set above or below an icon picture. [Fix] (Win) Canvas.Scroll: refreshes properly after scrolling. [Fix] (Win) Event order consistency: App.Activate event now fires after the Window.Open event in MDI applications. Also, the Window.Activate event now fires for MDI child windows when they are first displayed. [Fix] (Win) Event order consistency: closing an SDI application now suppresses extraneous EnableMenuItems and Deactivate events from firing. [Fix] (Win) FolderItem.CreateBinaryFile: BinaryStream class returned instead of a TextOutputStream. [Fix] (Win) Graphics.FillPolygon: passing in no points no longer crashes. [Fix] (Win) ListBox: vertical ScrollBar moved down one pixel (it now looks better). [Fix] (Win) MenuBarVisible: SDI applications again supported. [Fix] (Win) Strings: string comparisons on Windows NT now work with double byte characters. Also fixes the problem with including a NULL character within the string, the string comparison now works as it does on non NT systems. [Kis] (Mac) EditField: single-line unstyled EditFields currently suffer a variety of shortcomings, including the following; don't support carriage returns, not all properties/methods (e.g. SelText) are yet implemented, vertical line position is not always appropriate, font glyphs don't always match those produced by DrawString [Kis] (Win) Event order consistency: Window.Activate -- if the child window in an MDI application is originally hidden, then displayed (in a timer action event for example), the Activate event will not fire the first time.
