OpenTK will now use the same GLXFBConfig to create the INativeWindow
and IGraphicsContext on Linux/X11. This resolves an issue where OpenGL
3.x contexts could not be created on some graphics drivers (e.g.
nvidia binary.)
To do that, we need a custom InputOnly window. This window is only used
for receiving the exit ClientMessage - XI2 input is still received
through the root window.
Fixes issue https://github.com/mono/MonoGame/issues/2711
You cannot create an X11/OpenGL context without the GLX extension.
OpenTK will now throw a `NotSupportedException` when this condition is
encountered.
In some cases, it may be possible to enable the EGL backend by passing
`GraphicsContextFlags.Embedded` to the `GraphicsContext` constructor.
OpenTK uses the win32 wheel coordinate system, where
(+h, +v) = (right, up). XI2 uses (+h, +v) = (right, down)
instead, so we need to flip the vertical offset.
Fixes issue #133 and https://github.com/mono/MonoGame/issues/2686
This was caused by calling XDestroyWindow inside Dispose(), or
by processing events after calling XDestroyWindow. Pending events
are now discarded when Close() is called and not cancelled, and
XDestroyWindow is only called if the window exists.
We now use the display connection specified in EglWindowInfo
throughout the EGL backend, instead of opening new connections
in EglGraphicsMode. This fixes EGL errors in
Egl.CreateWindowSurface.
As part of this fix, all instances of
IPlatformFactory.CreateGraphicsMode() have been removed. This
API is no longer used in OpenTK 1.1
We have to load statically exported entry points using the regular OS
symbol loading facilities, and only use eglGetProcAddress for
extensions.
Fixes crash in https://github.com/mono/MonoGame/pull/2377
The scrolling valuator offsets are now calculated correctly, based on
the number of set bits in the valuator mask.
Additionally XI2Mouse now runs on a background thread, using blocking
XIfEvent. This should improve resonsiveness and reduce CPU usage, due
to reduced polling.
NativeWindowBase will now clear all keyboard keys when losing focus.
This prevents keys from getting stuck when refocusing the window.
[Win] Also fixed WindowState.Maximized when WindowBorder is Hidden and
the window is minimized.
After many hours of fighting with xlib, the monster is slain and
WindowBorder/WindowState changes now take effect without messing
up the window size or position on the desktop.
Phew!
