X windows, wxWindows. Each platform has its own way of returning
a variable length string, and its own rules about how you're supposed
to dispose of the string. Now all platforms do the same thing: they
allocate a Bit8u buffer with C++ "new" and copy the clipboard data in,
then release the clipboard data in the platform-specific correct way.
The Bit8u buffer is sent to the keyboard code, which frees it with
delete [] when finished.

the terminology a bit. In particular, the term "gui" has started
to mean different things in different contexts, so I've defined
some more specific names for the parts of the user interface, and
updated comments and some variable names to reflect it. See
siminterface.h for a more complete description of all of these.
VGAW: VGA display window and toolbar buttons, the traditional Bochs
display which is ported to X, win32, MacOS X, etc. Implemented
in gui/gui.* and platform dependent gui/*.cc files.
CI: configuration interface that lets the user change settings such
as floppy disk image, ne2k settings, log options. The CI consists
of two parts: configuration user interface (CUI) which does the
actual rendering to the screen and handles key/mouse/menu events,
and the siminterface object.
CUI: configuration user interface. This handles the user interactions
that allow the user to configure Bochs. To actually change any
values it talks to the siminterface object. One implementation of
the CUI is the text-mode menus in gui/control.cc. Another
implementation is (will be) the wxWindows menus and dialogs in
gui/wxmain.cc.
siminterface: the glue between the CUI and the simulation code,
accessible throughout the code by the global variable
bx_simulator_interface_c *SIM;
Among other things, siminterface methods allow the simulator to ask the
CUI to display things or ask for user input, and allows the CUI
to query and modify variables in the simulation code.
GUI: Literally, "graphical user interface". Until the configuration menus
and wxWindows came along, everyone understood that "gui" referred to the
VGA display window and the toolbar buttons because that's all there
was. Now that we have the wxWindows code, which implements both the VGAW
and the CUI, while all other platforms implement only the VGAW, it's not
so clear. So, I'm trying to use VGAW, CI, and CUI consistently since
they are more specific.
control panel: This has been used as another name for the configuration
interface. "control panel" is also somewhat unspecific and it sounds
like it would be graphical with buttons and sliders, but our text-mode
thing is not graphical at all. I've replaced "control panel" with
"configuration interface" wherever I could find it. In configure script,
the --disable-control-panel option is still supported, but it politely
suggests that you use --disable-config-interface instead.
- clean up comments in siminterface,wx* code
- add comments and examples for bx_param_* and BxEvents
- remove some obsolete stuff: notify_*_args,
bx_simulator_interface_c::[sg]et_enabled() methods
- in siminterface.cc, move a few bx_real_sim_c methods to where they belong,
with the rest of the methods. No changes to the actual methods.
- remove some DOS ^M's which crept in and confused my editor.
the guest OS. The shortcut can be defined in the bochsrc or in the config
interface. It is possible to change it at runtime.
These shortcuts are currently recognized:
ctrlaltdel, ctrlaltesc, ctrlaltf1, alttab
Here is the list of changes:
* userbutton.h and userbutton.xpm added in gui/bitmaps
* config options for the userbutton shortcut added
* initialize the new button in the gui.cc
* the new userbutton handler generates keypresses and relaeses depending on
the shortcut keyword
* the gui stops adding buttons to the headerbar if not enough space is left.
This can happen when the screen width is 320 pixels (done for X11 only).
* TODO: build a dialog box for the wxWindows gui
* dimension_update() stores the global variables columns, rows and
font_height_orig; it uses X font sizes to recalculate the screen size
* text_update() uses the columns, rows and X font sizes when redrawing the
screen; it adjusts the cursor shape using the font sizes
- 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.
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
X servers that I've seen, however on other X servers it makes all
key mappings into absolute junk. We need to continue to work on this
patch to support all X servers and all key maps.
<dieter.mittelmaier@freenet.de> which fixes X11 keyboard mapping
on German keyboards using Keycodes instead of Keysyms.
His comments are:
> I mapped your BX_KEY-defines in gui.h to values from XFree
> ../keycodes/Xfree86. Keysyms in x.cc would now translated
> to keycodes. Now I can use german or us keyboard-layout in
> win95 and all works well.
> Note: Changing keyboard layout in win95 to en works too
> Also you must change keyboard setup in win95 to AT-Enhanced 101/102 keyboard
which notifies them that the mouse_enabled bit has changed. Now that
mouse_enabled can be initialized or modified by parameter events in
addition to GUI events, the guis must be prepared for it. I have pasted
empty method definitions into mouse_enabled_changed_specific for all
guis except for X11, which I did the right way. The implementation
of this function must use the argument "val" rather than reading the
parameter.
been converted into parameters temporarily have the letter "O" appended
to their name. I don't want to keep it this way, but it has helped
in the conversion process because the compiler refuses to compile the
old uses of the name. Before I started using the "O" trick, there were
many bugs like this: if (bx_options.diskc.present) {...}
This was legal with the new parameters, but it was testing whether the
parameter structure had been created, instead of testing the value of
the present parameter. Renaming present to Opresent turns this into
a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid. I can no
longer support this and continue progress.
declared as bx_param_c * types in the bx_options structure. They are
initialized in main.cc (bx_init_options) with default values.
Access to parameters of this type should always be like this:
bx_options.mouse_enabled->get ();
bx_options.mouse_enabled->set (newval);
Eventually I will be transferring all options to this format.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.
In general this provides a generic interface for logging.
logfunctions:: is a class that is inherited by some classes, and also
. allocated as a standalone global called 'genlog'. All logging uses
. one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
. class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
. respectively.
.
. An example usage:
. BX_INFO(("Hello, World!\n"));
iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance. It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf(). At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.
More cleanup is coming, but this works for now. If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.
