- Gui4Cli VERSION 3.0 - April 1997 - Changes
- -----------------------------------------------------
-
- ************ VISUAL EDITING :
- -------------------------------
-
- - You can now visually edit guis with CONTROL-mouseclick.
- Gadgets/Graphics/Icons etc can be moved, resized, cloned into
- other windows, deleted and the gui can be saved out.
- Read all about it..
-
-
- ************ LISTVIEWS :
- --------------------------------
-
- - Handling Listviews has changed and so have the relevant listview
- commands. Listviews are now handled by CURRENT LISTVIEW and
- CURRENT LINE of the current listview.
-
- The listview commands no longer have the GuiFile GadID arguments
- but instead act on the CURRENT listview and it's CURRENT line.
-
- - LVUSE GuiFile GadID - will make the specified listview the CURRENT
- one and all the LV internal vars will reflect this. When the user
- clicks on a listview, that LV is automatically made the CURRENT LV.
- This command is to allow you to specify any other LV you may want.
-
- - LVGO first|next|prev|last|#LineNumber
- will change the CURRENT LINE to the line specified (without moving
- the actual listview visually).
-
- - LVSEARCH string CI|CS First|Next
- will search the listview for a certain string (CI=case insensitive,
- CS=sensitive) and will return with the first/next lines found.
- The listview's internal vars will point to the line found or "",
- for no (or no more) lines
-
- - LVMODE NUM|TXT|MULTI|DIR will change the listview's mode on the
- fly. Watch out though.. strange things may happen.
-
- - Listview loading of files is now faster.
-
- - You can now use the ARROW buttons to move a listview. You must NOT
- have declared a "xONKEY #R" command for this to happen. G4C will
- itself decide which LV to move (in a totally intuitive way). You
- can use up/down or shift up/down (for top/bottom) or control up/down
- for fast scrolling, or left/right or shift/control left/right.
-
-
- ************ IMAGES :
- --------------------------------
-
- - Now Images can be used, via the datatypes.library (OS V39+ only)
- Images are handled differently from icons, so that memory is saved.
- You first load an image and give it a "Alias" (i.e. any name you want,
- to which you can thereafter refer). Then you can use it in many guis,
- as a background or as an Image, without having to load an other copy
- of it. When you're done, you unload it..
-
- Image commands :
-
- o LoadImage ImageFile Alias ScreenName|NoRemap
- will load the ImageFile, call it the Alias you gave and if you give
- a screen name, the image will be remaped to that screen's colors.
- If "NoRemap" is given, the image will not be remaped.
-
- o UnloadImage Alias - will unload that image
-
- o WinBackground IMAGE Alias 0
- will use the (already loaded) image and tile it to the window's
- background.
-
- o IMAGE Left Top Alias
- will place the (already loaded) picture at the position specified.
- L T of -1 means center in window.
-
- o ChangeImage GuiFile GadID Left Top Alias
- will change the specified picture, to the "Alias" named picture
- which must have already been loaded. L T of -1 means position unchanged.
-
- IMPORTANT !!!
-
- O ICON L T IconName - is now used (instead of IMAGE) for displaying a
- non-clickable icon (sorry about any changes you have to make..)
-
-
- *********** NEW GADGETS/EVENTS :
- --------------------------------
-
- - xAREA L T W H COMP|BOX|NONE
- is a area hit gadget, like an invisible Button. Nothing will be
- shown unless the gadget is hit, whereupon it will COMPlement the
- area, or draw a BOX around it, or leave it alone (NONE).
-
- - xPALETTE L T W H
- will draw a palette gadget from which you can choose colors.
- Every time a color is selected, the palette will "happen" and the
- internal variables COLOR.R, COLOR.G, COLOR.B, COLOR.NUM, COLOR.TOTAL
- will contain the R G B values, the color number and the total number
- of colors. The number of colors is taken from the screen that the
- window with the palette gadget will open on.
- You can update a palette by choosing an other color :
- > update GuiName gadID NewColorNumber
- Look at the palette.gc gui to see an example
-
- - GAUGE L T W H IN|OUT BUTTON|RIDGE|ICONDROP APEN BPEN PERCENT
- will draw a gauge which you can give a gadid to and thereafter update
- as you need. The arguments are the same as for a BOX excpept for
- APEN = the number of the foreground color, BPEN = background color
- PERCENT = the starting percentage.
-
-
- *********** OTHER CHANGES :
- ---------------------------
-
- - Also added : ELSEIF and ELSEIFEXISTS
- which act the same as a new if within an if construct and can also
- deal with AND/OR etc constructs.
-
- - Also added : OR, AND, ORIFEXISTS, ANDIFEXISTS
- which take the same arguments as the respective IF and IFEXISTS
- statements and which *MUST* follow immediately after an IF or IFEXISTS
- or an ELSEIF or ELSEIFEXISTS.
-
- AND and OR also work with the WHILE statement.
-
- The above commands allow for some really tricky logical sequences,
- so be sure you have it right. Use the DEBUG option to see how they work.
-
- - Added disk information (sizes etc) in the device list of the listviews.
- Disk Errors or validation will also be shown (if they happen).
-
- - Made the following change to env: Variable notation :
- .MyVar denotes an env: variable called .MyVar (as you knew)
- ..MyVar denotes an env: variable called MyVar (new)
- i.e. a double full stop now denotes an env:variable *without* the
- starting full stop.
- This allows you to set/read "normal" env variables also.
-
- - The COPY command is now smarter. It will understand if you give a
- file name (instead of a dir) as the destination and create or overwrite
- the destination file. In short you can use it as 'copy as'.
- This is *not* the case with ACTION or LVACTION.
-
- - CALCVAR ResultVar Argument operator Argument
- will provide some means of calculating. The Arguments *must* be (or
- evaluate into) numbers and the result of the calculation will go into
- ResultVar. All calculation are *Integer* only!
- As with SetVar, you can also do this which means the same thing :
- ResultVar == Argument operator Argument (i.e. MyVar == 2 * 3)
- Operators are : + - * / also % (modulus) and ^ (to the power of)
-
- - VARPATH VariableSearchPath (Global Command)
- introduces the use of PRIVATE VARIABLES in Gui4Cli. This command
- is for defining paths for setting/searching private variables.
- With this, the variable system has changed dramatically and it is now
- better and faster. Read the variable section in the guide for more.
-
- - The INTERNAL VARIABLES have been rewritten completely, and there
- are now many more of them - look at the guide.
-
- - INFO GUI|GADGET|PALETTE|IMAGE Guiname|Guiname/GadID|ImageAlias
- will choose an other GUI (and thereby it's window and screen) or
- GADGET, PALETTE or IMAGE. After this command is issued, the respective
- internal variables will show you the information for the new item
- chosen.
-
- - PARSEVAR Variable
- is a command that will take a variable and split it up into arguments
- (words or quoted strings), returning them as internal variables.
- Note - the ; character ends the line (like in G4C)
-
- - A new form of DEBUG is available now. The old one still exists.
- The new one can be started/stopped at any time, with "Set DEBUG ON"
- (or off), without having to start up G4C in debug mode. The new
- one will show you cryptic statements instead of KeyWords and Opera-
- tors, but is otherwise same.
-
- - Also, if you press any key while in debug mode you'll get it's
- Code & Qualifier values.
-
- - xONKEY has now 2 new choices :
- xONKEY #R - means any raw key pressed
- xONKEY #V - means any vanilla key (apart from CONTROL keys).
- Raw keys are the arrows, help & function keys - all others are
- called "Vanilla" keys (God knows why..)
- The internal vars $$RAWKEY.CODE, $$RAWKEY.QUAL, $$VANKEY.CODE
- $$VANKEY.QUAL, $$VANKEY.LETTER, will contain the relevant key codes
- and qualifiers (qualifiers are the shift, alt etc keys).
-
- - Added \#number to command line parsing - allows to take control of
- outputing stuff to the console & printer.
- See the guide at: "Important topics/Constructing command lines"
-
- - Added new ACTION/LVACTION CLI command which will execute a command
- line recursively through dirs&subdirs substituting the $$FILE
- internal var in the command line given, with the file name.
-
- - SETGAD will now also take a range of gadgets to act on.
- SetGad MyGui 1/15 OFF - for example will set gadgets 1 to 15 off.
-
- - Added Event xLVHOOK which is for Multi and Dir LV's and will
- "happen" whenever an item on the LV is clicked on once.
-
-
- *********** Bug Fixes :
- -------------------------------
-
- - Fixed listview reading of binary files. Now the whole file is read.
-
- - Fixed H= operator # wildcard to recognise \n,\r,\t as text characters.
-
- - Changed c:Gui and it will now launch Gui4Cli *with* your default paths
- even if started up from the wb.
-
- - Fixed centering of gadgets using -1 -1 for left top (hopefully..)
-
- - EZReq will now use the calling gui's name as its title and not use the
- gui's window title as it did before.
-
- - Now if a window tries to open in a minimized size, it will be enlarged.
-
- - Fixed multiselect lv handling to recognise a double-click only when
- the user double-clicks the LV same line.
-
- - Fixed the BUFFERS=buffersize CLI argument. It actually works now..
-
- - Fixed window resizing with the GadChange command.
