Fix virtual display resolution change while in full screen mode.
Switching resolutions should keep the same full screen mode (integer,
full, no bars) unless a custom scale (using the zoom keys Control-- or
Control-+) has been selected.
Control-F is for switching forward through the full screen modes. Add
Control-Shift-F for switching backward through the full screen modes.
This allows reducing full screen mode without going through not full
screen mode.
Keys that are held down too early are ignored which makes it difficult
perform some tasks at startup:
- Shift key to disable extensions.
- Command-Option-O-F to enter Open Firmware.
- Command-Option-P-R to reset nvram.
- Capslock to boot MkLinux or Copland.
This change hopes to grab all the keys being pressed and post events for
all of them when the ADB bus is ready.
Create a mouse grab toggle event to toggle the mouse grab using the current window. After the toggle event is transmitted, transmit a mouse grab changed event so that all windows can update their title.
If the window's size is reduced such that the grabbed mouse is no longer inside the window, then a mouse click will go to another app. Therefore, check the mouse position and update if necessary every time the window changes size.
Added a third full screen mode which removes letterbox or pillarbox black bars.
Added Control-- and control-+ to decrease or increase the scale by a factor of 2^(1/8). This means the scale doubles or halves after pressing the same key 8 times.
drawable_w and drawable_h are floating point so that scaling is reversible (i.e. scaling from 100% to 800% and back to 100% gives 100% instead of 99 or 101%).
default_scale_x
Handle switching host resolution between Retina (HiDPI) and Low resolution modes. This involves updating the window scale factor.
Add window scale factor to window title.
A display begins in Windowed mode.
1) Press Control-F once to use full screen mode with integer scaling. If this mode is the same size as full screen mode then it is skipped.
2) Press Control-F again to use full screen mode. Smooth Scaling should be used for this mode if the scaling is not integer. Look at the Mac OS 7/8/9 window stripes to see the problem.
3) Press Control-F a third time to get back to windowed mode.
Fixed a bug where Control-S (Toggle Smooth Scaling mode) did not immediately update the display.
These keys only affect the current display.
update_window_title can be used to update statistics about the display (such as display resolution) or about DingusPPC in general (such as "mouse grabbed" status).
A DPPC_WINDOWEVENT_MOUSE_GRAB_CHANGED window event is added so that Display::handle_events can update the "mouse grabbed" indicator in each display window. The event handler doesn't check the window ID because the status should be reflected in all windows.
The SDL_WINDOWEVENT_SIZE_CHANGED event causes the window to update the display resolution indicator.
In the future, we might add indicators for HD and CD and floppy disk activity, etc. They will be handled by a window event handler or a general DPPC event handler.
Adds support for a --deterministic command-line option that makes
repeated runs the same:
- Keyboard and mouse input is ignored
- The sound server does a periodic pull from the DMA channel (so that
it gets drained), but only does so via a periodic timer (instead of
being driven by a cubeb callback, which could arrive at different
times)
- Disk image writes are disabled (reads of a modified area still
work via an in-memory copy)
- NVRAM writes are disabled
- The current time that ViaCuda initializes the guest OS is always the
same.
This makes execution exactly the same each time, which should
make debugging of more subtle issues easier.
To validate that the deterministic mode is working, I've added a
periodic log of the current "time" (measured in cycle count), PC
and opcode. When comparing two runs with --log-no-uptime, the generated
log files are identical.
Add new GamepadButton enum with bits corresponding to AppleJack button bits.
Both the AppleJack controller and the SDL GameController coincidentally define
one d-pad, two shoulder buttons, four face buttons, and three system buttons.
This makes mapping modern game controllers to the AppleJack straightforward.
Shutdown will enter the debugger or quit depending on the execution mode.
Quit is different from shutdown since it is triggered outside the guest by using the host Quit menu item.
Add absolute coordinates for tablets. Absolute coordinates is relative to window so it can't work for multiple displays? Doesn't work for single display without mouse driver modification.
Add arbitrary number of buttons. Previously, only one mouse button was supported.
Add arbitrary number of bits. Previously, only 7 bits per axis was supported which is good enough for relative movement but not absolute movement.
There are cases where when it's necessary (e.g. given uninitialized NVRAM,
the Beige G3 with the 10.2 install CD inserted will update the boot
device and restart to boot from it).
Restart support was done by wrapping the ppc_exec function in a loop and
checking for a restart power off reason. We also need to disconnect all
event listeners, since they will be recreated when the machine is
re-initialized.
Typing Control-C in Terminal app causes an interrupt signal that should enter the DPPC debugger but this only worked once since the signal handler never returned. Even if the signal handler reenabled the signal somehow, it calls enter_debugger recursively which is strange since the earlier calls to enter_debugger would never return.
Now the signal handler just sets a flag (power_on) which can be used to exit any loop (emulator loops, stepping loops, disassembly loops, dumping loops).
Main always calls enter_debugger now which calls the ppc_exec loop. The power_on flag will exit the ppc_exec loop to return to the debugger. Recursion of enter_debugger is eliminated except for calls to loguru's ABORT_F.
An enum power_off_reason is used to indicate why the power_on flag is set to false and to determine what happens next.
