"bx_bool" which is always defined as Bit32u on all platforms. In Carbon
specific code, Boolean is still used because the Carbon header files
define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
The bug was that some code in Bochs depends on Boolean to be a
32 bit value. (This should be fixed, but I don't know all the places
where it needs to be fixed yet.) Because Carbon defined Boolean as
an unsigned char, Bochs just followed along and used the unsigned char
definition to avoid compile problems. This exposed the dependency
on 32 bit Boolean on MacOS X only and led to major simulation problems,
that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
our own type. I chose bx_bool for several reasons.
1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
platforms, which makes it much less likely to have more platform-specific
simulation differences in the future. (I spent hours on a borrowed
MacOSX machine chasing bug 618388 before discovering that different sized
Booleans were the problem, and I don't want to repeat that.)
2. We still have at least one dependency on 32 bit Booleans which must be
fixed some time, but I don't want to risk introducing new bugs into the
simulation just before the 2.0 release.

specific to X windows. I changed a few names of variables and methods to
sound less X windows specific, for example in the BXKeyEntry struct
the "xwinKey" field is now called "hostKey".
- remove the hacks in bx_keymap_c::loadKeymap that checked that every
keysym started with "XK_". Now I can still make that check, but it
is done in x.cc's convertStringToXKeysym() instead.
- in sdl.cc, load the keymap in specific_init function. I had to
create a conversion function from SDL key names to SDLkey values.
I created a table of key names and associated values, and I just
do a strcmp on each name. It's not a fast algorithm obviously but this
conversion only has to be done for maybe 200 keys at startup time.
- added a key map file for SDL called sdl-pc-us.map. Since this has
basically all the SDLK_* symbols defined, it is a good starting point
if you need to make any other keymaps.
- modified: gui/keymap.cc gui/keymap.h gui/sdl.cc gui/x.cc iodev/keyboard.cc
- added: gui/sdlkeys.h gui/keymaps/sdl-pc-us.map
This must be done carefully though, because the call to SDL_WarpPointer
generates a mouse motion event of its own. To work around this, I have
added code that should ignore motion events generated by SDL_WarpPointer.
This should fix bug [ 619283 ] SDL: os mouse pointer leaves the window.
On Linux, SDL 1.2.3 it works fine.
set_text_charbyte()
- vga: store the address of the active charmap in the new variable
charmap_address
- vga: text mode hack removed. The write modes, operations and masks must be
used in text mode too.
- sdl: clear_screen() is not necessary when the charmap has changed
- win32: update only the changed font bitmaps before drawing the text
vga_charmap
- the SDL gui uses the charmap data for the vga text display
* TODO: implement this feature for other guis
- removed unused variables in sdl.cc and gui.cc
- fixed a warning in vga.cc
- The emulated vga card issues a dimension_update() using the real
screen dimensions and the real font height.
- The gui selects a font with the requested height or it recalculates
the screen height if the font height is not available.
- The text_update() function uses a new variable 'ncols' instead of the
fixed value of 80 for the number of text columns.
I have tested the changes with X11/Linux, SDL, wxGTK and win32. The changes
in the other guis are not tested yet.
- added toggle_mouse_enable() call to the handling of the middle mouse button
- removed break statement between SDL_MOUSEBUTTONDOWN and SDL_MOUSEBUTTONUP
- added prefix "SDL" in specific init
GUI specific paste functions for X11 and WIN32 in paste_handler() moved to
the new function
- get_clipboard_text() prepared for other GUIs
- set_clipboard_text() has now a return value (0 = failed or not implemented)
- use portable code in copy_handler() if set_clipboard_text() fails
- snapshot_handler() prepared for adding a file dialog call
- writing snapshot file in binary mode (LF->CRLF conversion already done)
GUI specific copy functions for X11 and WIN32 in copy_handler() moved to
the new function
- set_clipboard_text() prepared for other GUIs
- value of text mode cursor variables fixed (and renamed in x.cc)
- BX_ERROR message in snapshot_handler() fixed
Added control for 80x50 fonts
Added mouse input
Added mouse grabbing
Added automatic mouse grabbing when entering full screen
Added autoremoval of header when going fullscreen
Simplified a couple of graphic routines
