b782055b96 Kernel: Add an InterruptFlagSaver helper class. 
This is useful instead of InterruptDisabler in some cases.

0c38a4c30f WindowServer: Sever the WSWindow/Process link when the process dies. 
This fixes a deadlock where the WindowServer would get stuck trying to
acquire a dead process's event stream lock.

069d21ed7f Make buttons unpress when the cursor leaves the button rect. 
Implement this functionality by adding global cursor tracking.
It's currently only possible for one GWidget per GWindow to track the cursor.

9fa8d4e22f WindowServer: Rename the two painting phases. 
Work now happens in terms of two messages:

    - WM_ClientWantsToPaint
    - WM_ClientFinishedPaint

This feels fairly obvious compared to the old Paint/Invalidate.

bba21adae3 WindowServer: Rename WSEvent to WSMessage. 
Also do the same for WSMessageLoop and WSMessageReceiver. More to come.

7cf3c7461c Refactor GUI rendering model to be two-phased. 
Instead of clients painting whenever they feel like it, we now ask that they
paint in response to a paint message.

After finishing painting, clients notify the WindowServer about the rect(s)
they painted into and then flush eventually happens, etc.

This stuff leaves us with a lot of badly named things. Need to fix that.

d7d78670c9 Kernel: Add some logging for backing store get/release syscalls. 2019-01-25 00:13:37 +01:00

86eae0f8df Let userland retain the window backing store while drawing into it. 
To start painting, call:
gui$get_window_backing_store()

Then finish up with:
gui$release_window_backing_store()

Process will retain the underlying GraphicsBitmap behind the scenes.
This fixes racing between the WindowServer and GUI clients.

This patch also adds a WSWindowLocker that is exactly what it sounds like.

aa24547e12 Kernel: Finally stop exposing Region members to the public. 2019-01-24 18:09:46 +01:00

51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency. 
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

dbe83f3a83 Make it possible for userspace to alter window title/geometry. 
I'm not in love with this syscall API but it allows me to make progress.

dff5051905 Support polling with select() by using a zero timeout. 
Use this in WindowServer to avoid getting blocked in select() when
there are pending injected events.

dff70021ab Make it possible to invalidate only a portion of a window. 
Use this in Terminal to only invalidate rows where anything changed.

4fef895eda Rework WindowServer to use select() in its main event loop. 
The system can finally idle without burning CPU. :^)

There are some issues with scheduling making the mouse cursor sloppy
and unresponsive that need to be dealt with.

f7ca6d254d Tear out or duplicate what's unique for WindowServer from Widgets. 
This turned into a huge refactoring that somehow also includes
making locks recursive/reentrant.

6f61eb4a87 Slap an InterruptDisabler on gui$invalidate_window(). 
This is obviously not a permanent solution but it works now to allow
the windowing system to withstand invalidation spam.

b673c1a77d Build Painter & friends into LibC. Use it in the GUI test app. 2019-01-14 20:02:51 +01:00

0c5ecd303c Share GraphicsBitmaps between the windowing server and the client process. 
This is pretty cool. :^)

GraphicsBitmaps are now mapped into both the server and the client address
space (usually at different addresses but that doesn't matter.)

Added a GUI syscall for getting a window's backing store, and another one
for invalidating a window so that the server redraws it.

b0e3f73375 Start refactoring the windowing system to use an event loop. 
Userspace programs can now open /dev/gui_events and read a stream of GUI_Event
structs one at a time.

I was stuck on a stupid problem where we'd reenter Scheduler::yield() due to
having one of the has_data_available_for_reading() implementations using locks.

0ead888821 gui$create_widget() shouldn't try to make button corners opaque. 2019-01-13 07:33:10 +01:00

f7261d7b26 Let's use the existing Rect and Color types in the GUI API. 
Any type that doesn't depend on indirect data can probably be used here.
