the default Bochs method using the CTRL key and the middle mouse button there
are now the choices CTRL+F10 (like DOSBox) and CTRL+ALT (like QEMU).
* currently implemented in the X11 and SDL guis only
* TODO: porting to wxWidgets and Win32, documentation updates
'sdl'. Now both display libraries can be compiled together and used with the
'show ips' feature. TODO: win32-specific 'show ips' timers for 'rfb' and 'wx'
the existing runtime dialog ('textconfig' is still available)
- removed notify callback redirection from sdl.cc and win32.cc
- removed win32 specific code from textconfig.cc
- fixed parent window for folder selection dialog
- minor size changes in start menu dialog
editing the userbutton shortcut before sending it
- simple userbutton shortcut dialog for the X11 gui implemented
- small fixes in the X11 "ask" dialog code
Description from the author:
This API allows framebuffer device plugins to draw directly on to the
GUI's tile buffer and hence eliminates the need to memcpy(3C) tiles to
an intermediate buffer. Functions like update_hardware_cursor function
are rendered unnecessary as framebuffer device plugins can now draw the
full range of host colours. svga_cirrus will fallback to calling
graphics_tile_update without a hardware cursor if the GUI doesn't support
the new API. This patch includes implementations of graphics_tile_info,
graphics_tile_get, and graphics_tile_update_in_place (the new API) for SDL
and X11.
- new graphics update API implemented in wx and rfb
- common update functions for guis without support for the new API added (should
be removed after implementing the new API in all display libraries)
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
(based on a patch from Christopher Nelson <paradox@BBHC.ORG>)
* the win32 gui changes the bitmap settings using the bpp argument
* added stubs for all guis except win32
* descriptions of function dimension_update() updated
* renamed variables textres_x and textres_y to text_cols and text_rows
* use text_rows in function text_update() instead of the function argument
(unused for now - should be removed)
* fixed a warning (bochs_icon_bits)
and implemented in SDL
* sequencer controller register 0x01 bit 0 controls the width of the characters.
This value is used to calculate the screen width.
* attribute controller register 0x10 bit 2 controls the appearance of graphics
characters (ASCII 0xC0 - 0cDF). A change of this value forces a charmap update
to rebuild the font bitmaps.
* the SDL display library uses the new feature described above
* the other display libraries recalculate the screen width, since they are using
a fixed font width of 8 for now.
- VGA: attribute controller register 0x10 bit 2 (enable_line_graphics) does not
switch the palatte in CGA mode
- line offset handling simplified
- calculate textres_x and textres_y after changing the font dimensions
- unnecessary size check in function dimension_update() removed
palette - it's an index to the attribute controller palette index.
The new function get_actl_palette_idx() now returns the real DAC index.
The guis sdl, wx and x11 are using the new function. TODO: Fix this bug in
all other guis.
This fixes bug #614724: SDL can get stuck in full-screen mode, and provides
a framework for fixing the problem on other full-screen display libraries
such as term, svga, etc.
- add virtual method bx_gui::set_display_mode(mode) which can be overridden
by each display library class, if appropriate. This method is primarily
used when you run Bochs full screen, to tell the gui to switch from full
screen back to a mode where you can use the text console.
- There are two display modes: config and simulation. The mode is changed to
config mode during logfunctions::ask, during the runtime configuration menu,
and before displaying a debugger prompt. It is changed back to simulation
mode whenever instructions are running.
- Instead of being called directly through the global bx_gui pointer, the
bx_gui_c::set_display_mode() method is almost always accessed through
siminterface, like this:
SIM->set_display_mode (DISP_MODE_CONFIG);
SIM->set_display_mode (DISP_MODE_SIM);
Of course siminterface just passes the call on to bx_gui::set_display_mode().
I added it to siminterface so that the config interfaces could call it.
(They don't #include bochs.h so they can't access bx_gui.)

For a whole lot of configure options, I put #if...#endif around code that
is specific to the option, even in files which are normally only compiled
when the option is on. This allows me to create a MS Visual C++ 6.0
workspace that supports many of these options. The workspace will basically
compile every file all the time, but the code for disabled options will
be commented out by the #if...#endif.
This may one day lead to simplification of the Makefiles and configure
scripts, but for the moment I'm leaving Makefiles and configure scripts
alone.

"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
