The WIMP.
***************************************************************************
Change Log:
===========
Version 2.01
* Pending slot is now scanned on screen remapping
Version 2.02
* Wimp objects to > 256 pages, not >= 256
Version 2.03
* Message block too small is now checked for
Version 2.04
* Up-to-date value of CAOPointer is now read in OS_ChangeDynamic
- don't store CAOPointer in Service_NewApplication
- don't overwrite CAOPointer in Wimp_Initialise
Version 2.05
* Doesn't give address exception if 0 pages on startup any more
Version 2.06
* Wimp_ReportError <escape> now returns R1=1 or 2 as appropriate
Version 2.07
* Enable interrupts in Service_MemoryMoved (MOS bug)
Version 2.08
* Implement 2-way scrolling (drag_scrollboth)
Version 2.09
* Errors in Wimp_Poll are reported internally
* Disables escape conditions explicitly when Wimp_Poll is called
Version 2.10
* Remember pointer position over a mode change
* Use separate buffers for errors and starttask
(Problems if task causes an upcall)
* Report error if window deleted while dragging
* Stop dragging menu / dbox if menus closed
* *Help WimpSlot message altered slightly
* Move dynamic error block up 4 bytes
(It's overlaid on the error handler's buffer!)
* Ensure that Wimp_CreateMenu can return an error
* Check for errors while creating menu icons
* Delete menu window if error while creating icons
* Correct behaviour of caret / menu selection
Version 2.11
* Switch off pointer during 2-D scrolling
Version 2.12
* Return child's task handle from Wimp_StartTask (0 if dead)
Version 2.13
* Issue Open_Window_Requests after a mode change later on (ie. on the next
call to Wimp_Poll). This allows the window structure to be rearranged
on receipt of the Mode_Change message.
Version 2.14
* Bugfix to the above: a copy of the window list is made, in case
'backdrop' windows cause the window ordering to change, and the
background and iconbar windows are opened before the Mode_Change message
is returned, for compatibility.
Version 2.15
* Pointer readjustment when dragged window's extent changes is now fixed
properly (eg. when dragging Filer windows around, the pointer remains
over the resize box as it should).
Version 2.16
* WimpFlags CMOS bit 5 set => windows are allowed to go off the
bottom-right of the screen when being dragged by the title bar and when
Wimp_OpenWindow is called on them, unless bit 13 of the window flags is
set. Bit 14 of the window flags acts similarly, but is cancelled after
the next call to Wimp_OpenWindow relating to that window.
* Menus automatically have bit 13 of their windowflags set, as well as
dboxes (ie. windows which are opened using Wimp_CreateMenu or
Wimp_CreateSubMenu).
* When a window is toggled to full size, or when it is being reopened
because a mode change has occurred, the Wimp sets bit 14 of the window
flags first (so the next Wimp_OpenWindow will cause it to be kept on the
screen).
* Window extent supplied in Wimp_CreateWindow and Wimp_SetExtent is
automatically rounded to pixels by the Wimp.
* Double-click with different buttons is not allowed any more
* Fix bug: iconbar scrolls if the pointer is moved over either end, even
if a drag is in progress at the time
Version 2.17
* Fix bug: scroll bar dragging when window is partly off-screen
* Change pointer shape during double-click period
* Cancel double-click as soon as ptr moves away
* Cancel double-click if Wimp_DragBox is called
Version 2.18
* Fix bug: double-click ptr was not reset if shape <> 1
* If the menu-owning application knows about Wimp 2.18 (ie.
Wimp_Initialise was called with R0 >= 218, R1 = "TASK"), then messages
destined for menu windows are forwarded to the menu owner task.
* Wimp_GetMenuState can be called to determine the current state of the
menu tree (null tree if you are not the menu owner). It can also
determine the menu tree corresponding to a given window/icon if the
window is a menu or an open dialogue box.
Version 2.19
* Increase drag timeout period from 0.2 seconds to 0.5 seconds
* Report a drag button event immediately if the button is held down and
the mouse is moved by 16 OS units or more (as for double-click
cancellation).
Version 2.20
* Mode_Change message and reopen-window messages are only sent after a
mode change if an old-style task was not active when the call to
Wimp_SetMode was made, or at any time after that prior to the next
Wimp_Poll. This is so that old-style tasks do not get new-style windows
being reopened on top of them, if they execute Wimp_SetMode in their
!Run sequence (some programs such as !Delta execute Wimp_SetMode (R0=12)
to try to get the RISC OS Wimp to behave in a more compatible way with
the Arthur 1.20 version).
* Wimp_SetMode is now allowed while a command window is pending, without
activating it, and if the command window was already active before the
mode change, a VDU 4 is executed afterwards (to keep the text visible).
* *Wimp_SetMode <number> now causes SWI XWimp_SetMode to be called with
the number supplied. This command can be put into !Run files by users
for convenience (eg. if they prefer a certain package to work in a
particular mode). The default !Run files of packages should not cause
the mode to change.
Version 2.21
* New parameters to Wimp_CreateIcon allowed:
[R1,#0] = -3 => create icon on iconbar to left of icon handle R0
-4 => create icon on iconbar to right of icon handle R0
R0 = handle of icon to open next to, if [R1,#0] = -3 or -4
R0 = -1 => create icon at extreme left (-3) or right (-4)
This allows icons to be recreated and deleted (in order to change their
width, for example) such that they stay in the same relative position on the
iconbar.
Version 2.22
* BUG FIX: Wimp 2.21 preserves R10 (handle) over calls to 'openiconbar',
which means that the value of 'handle' is not set up correctly for the
next call to 'recalcposns' after a mode change. This in turn results in
OS memory being scrambled, and address exceptions occurring etc.
Version 2.23
* If application sets R0 >= 223 when calling Wimp_Initialise, then
Wimp_Poll or Wimp_PollIdle with R0 bit 13 clear, bit 22 set => R3 ->
poll word (must NOT be in application space). If R0 bit 23 is also set,
then the word is scanned by the Wimp at the start of the Wimp_Poll loop;
otherwise it is not scanned until just before the Wimp is about to read
the mouse (ie. after all messages have been delivered and
Redraw_Window_Requests sent). If the Wimp finds that the word is
non-zero, then it will return R0=13 from Wimp_Poll, with [R1,#0] =
address of poll word, [R1,#4] = contents.
Version 2.24
* Fix bug: the above stuff did not work for Wimp_PollIdle (the error "Bad
parameter passed to Wimp in R0" was returned, even if no bits above bit
23 were set in R0.
Version 2.25
* "*Wimp_SetMode" command changed to "*WimpMode".
Version 2.26
* Wimp automatically sets bit 14 of window flags on Wimp_CreateWindow and
Wimp_SetExtent. This forces new windows to be initially on-screen, but
allows them to be dragged off subsequently.
Version 2.27
* Menus and dboxes now get bit 14 set, rather than bit 13. This allows
them to be dragged off-screen after initial opening.
Version 2.28
* Bit 7 of R1 set on entry to Wimp_ReportError suppresses the 'beep' that
would normally occur if bit 4 of the WimpFlags was clear.
Version 2.29
* Drag movement limit increased from 16 to 32 OS units.
Version 2.30
* Double-click movement limit increased from 16 to 32 OS units.
* Extra sprites added: file_fea and small_fea.
Version 2.31
* Sprites taken out of Wimp and put into Desktop module
* Also spots when the Desktop module dies or re-inits
Version 2.32
* Don't give error on initialisation if ROM sprites can't be found
Version 2.33
* Fix problem with *WimpPalette opening the command window
* Fix syntax message for *WimpMode <n>
Version 2.34
* Make *IconSprites look for <file>23 if in mono mode
* Pick up DeskFS:$.Sprites or DeskFS:$.Sprites23 for ROM sprite area
* Add Wimp_ReadSysInfo R0=1 => R0=current Wimp mode
Version 2.35
* Fix bug: OpenWindowRequest messages should always be dealt with by the
Wimp, rather than going to the menu owner (even if he says he knows
about recent Wimps).
Version 2.36
* Message_ModeChange, and window re-opening, is only performed after
Wimp_SetMode if the new mode is different from the last mode for which a
message was returned.
* Iconbar doesn't scroll on a mode change
* Escape in a Wimp_ReportError box causes the non-highlighted box to be
selected, or the only box if it is highlighted. Any other key selects
the highlighted box, or the only box if it isn't highlighted.
* Maximum number of created windows increased to 256
* "Bad Wimp mode" error returned for Wimp_SetMode to double-pixel modes
Version 2.37
* If R0 >= 223 on Wimp_Initialise, then Wimp_Poll(Idle) with bit 24 set =>
save / restore FP registers.
Version 2.38
* Window flags bit 14 (force onto screen once only) moved to bit 21
* Window flags bit 14 set => drag ignores extent x1
* Window flags bit 15 set => drag ignores extent y0
Version 2.39
* Use double-width VDU-5 caret if pixel width <= 2 OS units
* Use double-width font caret if caret height > 12 pixel-widths
Version 2.40
* Fix bug: don't re-open backdrop and iconbar if same mode
Version 2.41
* Fix bug: the following calls should accept window -2:
Wimp_GetWindowState Wimp_GetWindowInfo
Wimp_GetWindowOutline Wimp_ForceRedraw
Wimp_DragBox Wimp_WhichIcon
* Caret made single-width again
* Free pool converted to words, so > 256 pages are allowed
Version 2.42
* Default action of f11 is to toggle the iconbar between front and back
Version 2.43
* Fix bug: Wimp_ForceRedraw with handle -2 didn't redraw the iconbar
Version 2.44
* *WimpMode <n> doesn't do anything if mode is already current.
Version 2.45
* Change f11 behaviour to toggle the 'back' bit of the iconbar
* Wimp_GetWindowInfo now accepts R1 bit 0 set => don't return the icon
definitions (ie. just return the window header). R1 bits 0..1 are
cleared before R1 is used as a pointer.
* Wimp_LoadTemplate now accepts R1<=0 => just return R1 = size of buffer
required, R2 = size of indirected data
Version 2.46
* Fix bug: Wimp_LoadTemplate mustn't check for R1 >= &8000.
Version 2.47
* Make Wimp_OpenWindow prevent windows getting bigger than the screen size
even if they're not being forced onto the screen.
Version 2.48
* If ptr_default sprite has its own palette, don't use Wimp palette
on mode change.
Version 2.49
* Ignore clicks on greyed-out menu items
* Return Message_MenusDeleted if menus deleted
* Return mouse clicks via messages if message queue non-empty
Version 2.50
* Look at ModeFlags HiResMono bit rather than Log2BPP = 0 to decide
whether to use DeskFS:$.Sprites or DeskFS:$.Sprites23 when Wimp starts
up, and whether to look for <name>23 in *IconSprites.
* Wimp_OpenWindow forces the window on screen if it was previously closed.
Version 2.51
* Make menu disappear if SELECT clicked on grey item
Version 2.52
* Allow interactive help to 'see' greyed-out menu items
* Setting menu flags bit 4 allows you to see submenus of grey items.
Version 2.53
* Issue Service_WimpPalette on Wimp_SetPalette
* Return R2 = sender's task handle from Wimp_Poll(Idle) if task knows
about Wimp 2.53.
Version 2.54
* Fix bugs: Call int_sendmessage_fromwimp rather than int_sendmessage to
give taskhandle 0 on return from Wimp_Poll.
Version 2.55
* Fix bug: *Iconsprites in mode 23 used wrong R2, giving "Bad file name ''".
Version 2.56
* Issue Message_MenusDeleted when escape kills menus
Version 2.57
* *IconSprites tries <filename>20 if <= 2 OS units per ypix
Version 2.58
* *IconSprites tries <filename><x><y><bpp>, then <filename>
It also uses the values cached on startup
* Wimp_ReadSysInfo (2) returns ptr to xeig,yeig,log2bpp
Version 2.59
* *WimpTask works from a dead task, by entering the Wimp as an
application, initialising and then doing the SWI Wimp_StartTask. It
then exits via OS_Exit.
Version 2.60
* *IconSprites now puts <x><y> or "23" on the end of the filename.
* Wimp_ReadSysInfo (2) returns ptr to suffix
Version 2.61
* Implement Wimp$State ("desktop" or "commands")
* Wimp_ReadSysInfo (3) returns state of commandflag
Version 2.62
* Wimp_ReadSysInfo (3) returns 0=commands, 1=desktop
* f11 causes iconbar to come to front if covered, and to the back
otherwise. When coming to the front, the backwindow bit is cleared, and
when going to the back,it is set.
Version 2.63
* Still send Message_ModeChange even if same mode, and still re-open
windows, but don't force windows onto screen u nless screen size smaller
in x or y.
Version 2.64
* Fix FP register saving, and set status=&70000 if not saved
* Fix scrolled menu dotted line redrawing
* Don't send iconbar to back on mode change
* Use OS_CheckModeValid when checking for HiResMono modes initially
* Clear bottom bits of palette entries in Wimp_ReadPalette
Version 2.65
* Don't send Message_SlotSize if slot is same size
* Report memory full errors in Wimp_SlotSize correctly
* Make OS_ChangeDynamicArea and findpages work with 16Mb
* Allow pointer to go off bottom-right in size dragging (this in fact
causes the window to expand in the other direction).
* Fix bug: don't zero bottom bytes in Wimp_ReadPalette
* Avoid 16-bit overflow when setting the pointer bounding box. This gets
round a problem with unbounded windows with extent > 2^16, where the
size drag bounds can be too big.
Version 2.66
* Fix bug: Wimp_SlotSize corrupted R4 on exit!
Version 2.67
* Fix bug: Wimp_LoadTemplate didn't count indirected data properly
* Fix bug: turn double-click ptr off if pending window deleted
* Fix bug: allow validation string pointer = 1 and indirected text size <=
0 in templates. This allows for indirected sprite icons, where the
'validation string' pointer is in fact the sprite area CB ptr (0 =>
system sprites, 1 => Wimp pool).
Version 2.68
* Add "-next" parameter to *WimpSlot command
* Make "-min parameter to *WimpSlot optional
Version 2.69
* Altered default Wimp palette so that the bottom two bits of R,G and B
are equal (for all but colour 8). This helps the Wimp and ColourTrans
to agree about the colours in 256-colour modes, and also results in
better matching colours from the Wimp.
Version 2.70
* Changed to use ResourceFS
* Included resource files inside module
* Accesses resources via WindowManager$Path
Version 2.71
* Implement *WimpWriteDir for changing to Hebrew mode
* Menus with title starting "\" are reversed
* Wimp_ReadSysInfo (4) returns current write direction
Version 2.72
* Fix bug: didn't initialise ROM sprites if loaded after ResourceFS
Version 2.73
* Added Wimp_CreateIcon window handles -5 to -8 (prioritised)
Version 2.74
* Fix bug: iconbar extent should be pixel-aligned
Version 2.75
* Fix bug: return click from menu icon if clicked as the mouse enters
Version 2.76
* Icons stored separately from windows. This allows window structs to stay still.
* Pass reason code messages <= CloseRequest through the message system
under task ID 'pmiW' ("Wimp"), this enables mode change to send open
messages for all windows.
* Send messages for all windows being opened after a mode change, and stop
using the stack to hold the window stacking order for this operation.
* Implement infinite windows.
* Backwindow bit slightly changed in meaning: now, the frontmost back
window determines where windows opened behind window -2 get opened; if a
specific window handle is given, even if that window is behind a back
window, then the opened window will open behind the window specified.
Version 2.77
* Handle rectangle area full redraw screen better.
Version 2.78
* Fix bug: address exception when clicking on greyed-out menu item
Version 2.79
* Iconize messages implemented.

12-Mar-92 Messages flag is initialised immediately after claiming ws to ensure
if errors are looked up during init (eg in ValidateMode) no address
exceptions occur (e.g. if invalid configured screen mode).
Fixes RP-0725 and RP-1679
---------------------------------------------------------------------------
Version: 3.09 Thu 19-Mar-92 Lawrence Rust
19-Mar-92 3.09 LRust - Redraw of pressed gadgets fixed to not leave in pressed state
*help text for WimpDragDelay etc. tidied.
Iconsprites now no longer merges the window border tools.
This speeds up *iconsprites and prevents address exceptions
caused by cached toolsprites having moved.
Wimp_SetCaretPosition now pages in task losing caret if icon
has indirected data.
---------------------------------------------------------------------------
Version: 3.10 Thu 02-Apr-92 Lawrence Rust
* Fixed caret positioning in writable icons by ensuring that
drawicon_system in Wimp04 adjusts for borders before calling
findtextorigin - thus text is correctly aligned in bordered icons.
* Menu titles can be indirected using bit8 of the first menu item
* KA validation string now causes caret to move to the same character
position within the new icon when up or down arrow pressed.
* Fixed bug RP-2025, adjust drag scroll bars without instant vertical effects
erroneously called a user drag routine, and went BANG!!
* Fix RP-1809, Wimp_ReportError now forces VDU output back to the
screen before drawing the error box, and restores re-direction and
other states on exit
* Fixed RP-1913, Wimp_Initialise now accepts any control character to
terminate the task descriptor string. Subr Count0 fixed to do this.
* Fix RP-1537. *WimpPalette now checks that there are exactly 16 palette
entries in the file, thus avoiding problems with the 256 colour variety
* KA validation string cause up/down arrow to move to end of new field,
fixes G-RO-7130, RP-1168
* Sprite highlighting changed again! fixes RR-1674 and Rp-1402
* Sprite graying changed again! fixes RP-2094
* Initptrs now preserves R0, preventing R0 from being corrupted on Service_Reset
* Fix RP-2148 and RP-2150 - F command in validation specifying font colours
now accepts lowercase hex colour numbers.
* Fix RP-2153 - Mode change now uses default colour mappings for the mode to ensure
the physical palette isn't changed by use of Wimp_SetColourMapping to alter
logical colour mapping. In addition Wimp_SetColourMapping also forces
re-caching of tool sprites to ensure the cached palette is correct.
* Fix die entry if tasks are active to restore R12 after (and not before!)
translating the CantKill error.
* Respond to service_InvalidateCache
* Add reason code 7 to ReadSysInfo to return Wimp version
---------------------------------------------------------------------------
Version: 3.11 Tue 07-Apr-92 Lawrence Rust
* 3D scroll bar routines fixed to only plot icons if clipping rectangle is
non null. Pressed hscroll bars drawn correctly. Fixes RP-1766 and other
3D tool complaints.
* Service_InvalidateCache disposes of tool_list only, redrawing window with
empty tool_list calls maketoollist to re-cache tool info.
---------------------------------------------------------------------------
Version: 3.12 Thu 16-Apr-92 Lawrence Rust
* ExitPoll only calls post filter if event in R0 is valid (ie not when
R0 is setup for Wimp_StartTask.
* ExitPoll call to portable module for non null events optimised.
* Recoded scanpollwords to use a packed list of pollword tasks to improve
search time. Fixes G-RO-7574
* Submenus now displayed immediately to right of arrow (left in hebrew), not
to right of window, in case title wider than item.
* Fixed template loading to correctly preserve file handle if insufficient
RMA to cache the file. Fixes RO-8608 (Acorn DTP not starting on 1 Mb machine).
* Wimp_ReportError correctly returns cancel if escape pressed with highlight on ok
---------------------------------------------------------------------------
Version: 3.13 Thu 23-Apr-92 Ran Mokady
* Remove input focus from iconized windows.
---------------------------------------------------------------------------
Version: 3.14 Fri 24-Apr-92 Ran Mokady
* Fixed redraw bug, caret size now takes into account the icon border.
---------------------------------------------------------------------------
Version: 3.15 Fri 24-Apr-92 Ran Mokady
* Stop text in non indirected sprite and text icons from being printed if an
error occurs when plotting the sprite. Fixes bug in !PinPoint.
