- Update List
- ===========
-
- 1. User Interface Toolbox
- =========================
-
- Toobox
- ------
-
- Acorn C/C++ version: 1.33
- Update version : 1.36
-
- - parent and ancestor components of a newly created Object are now
- correctly initialised to -1 (previously 0).
-
- - if a null event is delivered to the client application, it is
- ALWAYS let through, even if the client was apparently not
- expecting a null (as indicated by its event mask). This is
- because Wimp_StartTask returns in a manner which makes a null
- event appear to return from Wimp_Poll, and this must be passed
- through unclaimed, or Wimp_StartTask will cause a fatal error
- in the client. The only side-effect of this is that clients
- of the Toolbox may receive unexpected null events, if an Object
- Module has enabled them on its behalf.
-
- - Object IDs are now more likely to remain unique over time.
- Previously an Object ID was just an RMA address, and so deleting
- an Object and then immediately creating another Object had a high
- probability of "re-using" the deleted Object's ID. Now we
- have a counter which is OR'ed into the address. This means that
- Object IDs now appear in a different range of integer values,
- but this will not affect client application use, since no
- interpretation may be applied to an Object ID.
-
-
-
- Iconbar
- -------
-
- Acorn C/C++ version: 1.11
- Update version: 1.12
-
- - corrected interactive help behaviour. Previously the module only
- checked the icon number of a help request, without checking it
- was for the iconbar window handle - this would cause interactive
- help for some windows to "flicker".
-
-
-
- ColourDbox
- ----------
-
- Acorn C/C++ version: 0.14
- Update version: 0.15
-
- - doesn't RMEnsure 310support module for versions of RISC OS later
- than 3.10.
-
-
-
- ColourMenu
- ----------
-
- Acorn C/C++ version: 0.16
- Update version: 0.17
-
- - slight memory leak removed when a colourmenu was shown via
- Toolbox_ShowObject. Previously, showing a ColourMenu without
- a "none" entry would leak 5 bytes.
-
-
-
- FileInfo
- --------
-
- Acorn C/C++ version: 0.13
- Update version: 0.14
-
- - memory leak removed from FileInfo_GetModified.
- Previously it would leak 32 bytes on each call.
-
-
-
- FontDbox
- --------
-
- Acorn C/C++ version: 0.13
- Update version: 0.14
-
- - new Window template has 10pt gadget same size as the other
- font size gadgets.
-
-
-
- Fontmenu
- --------
-
- Acorn C/C++ version: 0.16
- Update version: 0.17
-
- - corrected behaviour on ADJUST-click. Previously two submenus would
- be created if Fontmenu Object was created as a submenu, resulting
- in incorrect font choice events.
-
-
-
- Menu
- ----
-
- Acorn C/C++ version: 0.22
- Update version: 0.24
-
- - fixed Menu_SetTextEntry. Previously if the old entry and the new
- entry were identical in the first character, then an infinite loop
- would result. This also fixes Menu_SetEntrySprite and
- Menu_SetTitle in the same respect.
-
- - menu entries which use sprites now look for those sprites in the
- client's sprite area first and then the Wimp sprite area.
- Previously such sprites had to be in the Wimp sprite area.
-
-
-
- PrintDbox
- ---------
-
- Acorn C/C++ version: 0.08
- Update version: 0.09
-
- - help string for the "copies" gadget corrected. Previously it was
- the same as the "scale" gadget help text.
-
- - allowable chars for the from/to gadgets corrected to disallow the
- character 'a'. Previously 'a' was a permitted character.
-
- - uses SWI PDriver_Info to get the currently selected printer rather than
- Printer$.
-
-
-
- SaveAs
- ------
-
- Acorn C/C++ version: 0.10
- Update version: 0.11
-
- - uses the hourglass when saving on behalf of "type 1" clients.
-
- - setting of the "safe" bit corrected. Previously "safe" bit
- was being set after certain error conditions.
-
- - "type 1" clients now correctly set estimated file size at the
- beginning of a data transfer. Previously this was always 0.
-
- - corrected behaviour of "type 2" clients when "Save" is clicked
- and the filename chosen is "long" (255 chars). Previously
- this caused undefined behaviour in the client application.
-
- - SaveAs_GetFileName corrected. Previously this would also set
- filetype to 0.
-
-
-
- Scale
- -----
-
- Acorn C/C++ version: 0.10
- Update version: 0.11
-
- - corrected delivery of events when client's own dbox is used for
- a Scale Object. Previously scale factor was always reported as
- 0.
-
-
-
- Window
- ------
-
- Acorn C/C++ version: 1.29
- Update version: 1.31
-
- - removed memory leak when Window deleted which had a radio button in
- it. Also removed memory leak when task exits with Windows still
- in existence which have toolbars.
-
- - made decimal point character used in number ranges dependent on
- currently configured territory.
-
- - behaviour of draggable gadget corrected to allow the pointer to the
- edge of the screen when dragging. Previously the dragged object
- was bound to the screen.
-
- - improved support for new gadget types.
-
-
-
- 2. C++ Compiler
- ===============
-
- Acorn C/C++ version: 3.0
- Update version: 3.1
-
- - c++ command now calls the C preprocessor in ANSI mode to allow ANSI
- preprocessing directives (eg ##). Previously this caused compilation
- errors when using assert.h.
-
-
-
- 3. C Compiler
- =============
-
- Acorn C/C++ version: 5.05
- Update version: 5.06
-
- - corrected behaviour using shorts with right-shift and addition.
- Previously, the register allocator was wrongly removing narrowing
- operations; ie where only 16 bits of result are used in a = b + c, it
- is deduced that only 16 bits are needed from b and c; the allocator
- was wrongly applying this to a = b + (c>>16) as well.
-
- - corrected behaviour in basic blocks which caused fatal internal error:
- insertblockbetween.
-
-
-
- 4. Tools
- ========
-
- !ResEd
- ------
-
- Acorn C/C++ version: 0.28
- Update version: 0.32
-
- - FontDbox editor dbox now consistent with other dboxes.
-
- - Window extent and coords fields now allow -999999 to 9999999.
- Previously limits were -9999 to 99999.
-
- - Title of String Set dbox corrected from "String Set" to
- "String set".
-
- - Redraw problem fixed for gadget bbox "ears" under certain
- conditions (eg ADJ-drag on a resize handle).
-
- - Support added for unknown Objects and Gadgets. These can now
- be edited using a generic word offset interface. Previously
- they were faulted.
-
- - Gadgets and objects with zero-size bodies are now processed
- correctly.
-
- - The "Import warning" dialogue box now responds correctly to a
- RETURN keypress.
-
-
-
- !ResCreate
- ----------
-
- Acorn C/C++ version: none
- Update version: 0.03
-
- - new application designed to "bootstrap" the process of creating
- new Object Templates. This application can be used to create a
- blank Object Template, allowing the ResEd palette file to be
- added to.
-
-
-
- 5. Libraries
- ============
-
- C++Lib
- ------
-
- - if attached to a tty, cin is now line buffered (ie input is terminated by
- EOL rather than EOF - Ctrl/D).
-
-
-
- EventLib
- --------
-
- - event_deregister_toolbox_handler now correctly removes the handler.
- Previously all toolbox handlers remained registered for the lifetime of
- the client application.
-
-
-
- FlexLib
- -------
-
- - new library formed by extracting c.flex from RISC_OSLib which was part of
- the Desktop C product. Use is described in the header file h.flex.
- This library is mostly API-compatible with RISC_OSLib except flex_init
- which now requires 2 extra parameters to deal with error handling.
-
-
- ToolboxLib
- ----------
-
- - h.wimp: corrected the typedef for a WimpWindow. Previously it had a
- single Wimp Icon block at the end of it, thus making sizeof(WimpWindow) 3
- words too big.
-
