Update of /project/mcclim/cvsroot/mcclim/Backends/beagle
In directory common-lisp.net:/tmp/cvs-serv6872/beagle
Modified Files:
README.txt beagle-backend.asd
Log Message:
Tidying of mirror functionality; menus are now drawn in the correct places,
although motion events over 'popup' menus is intermittent, and motion events
appear to be ignored altogether over command menu panes.
Some reorganisation of the README.txt file in an attempt to prioritise
future work.

KNOWN LIMITATIONS / TODO LIST
+--- Button pane highlighting and mouse event handling ---
+
+!5. Mouse down / up on buttons appears not to work very well unless the frame
+ containing the buttons is the only active frame.
+ Actually, this ^^^ seems to work fine, but the highlighting for button
+ gadgets looks screwy under OS X.
+ (Think there is a problem with tracking rectangles not being set for
+ panes. Another alternative relates to the calculation of pointer position
+ in the MOUSE-ENTER/EXIT event generator.)
+
+ Also, think 'drop down' menus aren't working for similar reasons; either
+ to do with McCLIM not understanding where the pointer is, or something to
+ do with tracking-pointer.
+
+
+!21. Highlighting on mouse overs isn't quite right; artefacts are left on the
+ display after the mouse has moved out of the target object bounding
+ rectangle (most easily visible in CLIM-FIG again, and also in the
+ directory view of the Listener (look at the highlighting of the images).
+
+
+--- General windowing and drawing ---
+
+!24. Testing + further work on patterns and stencils.
+
+
+!26. Minimising frames and then restoring them leads to the frame not
+ being drawn properly; it looks like 'drawRect' is invoked (as
+ expected), but nothing to tell McCLIM to redraw the whole frame.
+ Suspect a notification is sent... needs investigation.
+
+
+--- Large output histories ---
+
+!23. Large output histories: the transformations and geometry calculations
+ go wrong when the output takes up more than 2^16 pixels; the medium
+ should be used to account for this (it does in CLX) but for some
+ reason it isn't. Can work around by changing every #x8000 in
+ UPDATE-MIRROR-GEOMETRY (see sheets.lisp in core) to #x800000 (or larger)
+ but this will fail eventually (i.e. with a large enough output
+ history), so it needs sorting properly.

7. Keyboard events are not handled "properly" as far as any OS X user will
be concerned; only the ASCII characters are recognised, along with
simple modifiers. It's enough to enter commands and edit the command via
Emacs-like CTRL-B (backward char), CTRL-F (forward char), CTRL-A (start
of line), CTRL-E (end of line), CTRL-D (delete char).

+ intermittent if the right mouse button is released. Not sure if this
+ makes sense... (note: right-click to bring menu up, the right click

+-16.- Windows are put on screen very early in the realization process which

+
+ This is now resolved for application frames (put up when ENABLE-FRAME
+ is invoked) but not for menu panes (since ENABLE-FRAME appears not
+ to be invoked at all for them). Resolved (kind-of) for menu frames too
+ now; these are put up during the ADOPT-FRAME functionality.

+ Drawing is still rather messy though, more investigation needed.

*DEFAULT-FRAME-MANAGER* instead.
FIXED 17.MAY.2005 - *beagle-default-frame-manager* is no more (well...
it's still there but it can be ignored to all intents and purposes).

It's only a matter of a pixel, maybe 2 in the worst case I've seen.
