When the user presses the "Reset" button on the gui ribbon, we need to
clear the active status of all statusbar items or they remain set after
the reset occurs.
This is mentioned in issue #123
As an example, when saving the state of an emulation, especially one
that has large image files and a large memory setting, there is a pause
between the time you choose a directory to save to, and the MessageBox
that states that the state was saved. During this time, there is no
indication that Bochs is doing anything. As far as the user is
concerned, Bochs froze.
So, this PR adds the capability to display a _Modeless_ message box. To
do so, at any point you need a message box shown, allowing other things
to continue to happen (SYNCHRONOUS), simply call the following line:
`void *hwnd = SIM->ml_message_box("Message Box Title", "Message Box
Text");`
Then after the task has been performed, remove the message box:
`SIM->ml_message_box_kill(hwnd);`
The function is implemented in all configurations via virtual calls,
however, the creation of the message box is currently only implemented
in the Win32 configuration. Other configurations will need this
implemented, though I do not have those configurations to test with,
except the text only config. I may get around to it :-).
This also currently only displays as the state is being saved. To
display when the state is being restored should now be a simple task by
adding the two lines shown above to the associated function.
The only drawback with this is that if the state is considerably small,
the save will take just a second or less. If so, this window will show
and then instantly be removed, possibly confusing the user. _What was
that!!_
- The X gui behaviour should be unchanged.
- RFB / vncsrv: cursor shape fixes.
- Changed format of the font parameters to fix "double width" characters.
- Restore guest charmap after leaving gui console.
- Now using text_update_common() for the new text update API in addition to the
graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
draw_char(). The method set_font() is optional and it can be used to update
font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
and h/v pel panning are supported by the RFB gui. The legacy text_update()
method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.
- Added support for split screen mode and horizontal pel panning.
- Text mode cursor now correctly visible independent from blink state.
- Workarounds for the existing text_update() API.
set accordingly.
TODO #1: Text mode features split screen and h/v pel panning missing for now.
TODO #2: Show error messages related to dialogs in message boxes.
- Enter command mode with F7 key only, but no modifier pressed.
- Pressing / releasing modifier key only doesn't leave command mode.
- Changed some headerbar button access keys using modifiers (e.g. shift + c
calls config button handler). See user doc for all supported keys.
with keypress combination. This feature is currently supported by the x and
sdl2 guis only and it can be activated with the "cmdmode" (command mode)
display library option. If enabled, pressing the F7 key enters this mode (shown
in the leftmost statusbar item) and the next keypress (except F7) is not sent
to the emmulated keyboard. If the key is supported, the associated action is
performed. Both x and sdl2 support calling the handlers of 8 headerbar buttons.
The sdl2 gui additionaly supports toggling fullscreen / windowed mode.
Supported keys:
c - Press the Copy button
e - Press the Config button
f - Toggle fullscreen mode (sdl2 only)
n - Press the Snapshot button
o - Press the Power button
p - Press the Paste button
r - Press the Reset button
s - Press the Suspend button
u - Press the User button
F7 - Send F7 keypress to emulation
TODO: add support for other guis.
- Only keep the comments for the specific gui methods in nogui.cc and add
references to this file in all other gui sources.
- Changed the order of methods and added some useful comments in gui.cc / gui.h.
- Minor other cleanups
- Moved helper function reverse_bitorder to the common gui code.
- In console_refresh() call flush() after text_update().
- Started preparing rfb, sdl, sdl2 and vncsrv gui for using the console.
- Some other small cleanups.
- vncserv.cc: Fixed sdl font issue.
- Don't check for mouse toggle event if console is active.
- Added support for blinking cursor.
- Added stubs in the gui code to reduce BX_USE_TEXTCONIG usage in x.cc.
code. Now the runtime configuration runs in the Bochs window instead of
console / xterm. The simulation screen is restored when the
simulation continues. This feature can be implemented for all guis
without gui dialog box support (e.g. sdl2/sdl2 on non-win32 platforms, rfb).
- Force a status bar update after unregistering an item.
- Added status indicators for USB disk and cdrom.
- Handle USB device disconnect in the runtime config handler, too.
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.
The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
