This patch adds a workaround for WM_STYLECHANGED messages that are not
delivered when running on Mono/Windows. If we detect Mono, then we call
HandleStyleChanged() directly in order to update the internal state of
our WinGLNative instance.
PlatformFactoryBase provides a common base interface for platform
backends. Platform backends should inherit from PlatformFactoryBase in
order to reduce code duplication.
LegacyJoystickDriver implements the legacy IJoystickDriver interface
(GameWindow.Joysticks) in terms of the new IJoystickDriver2 interface
(OpenTK.Input.Joystick).
This removes a large chunk of code from each platform backend, as they
no longer need to implement IJoystickDriver themselves. Additionally,
it adds support for device hot plugging which was previously missing.
DeviceAdded already checks that devices conform to the desired usage
pages. Checking again in DeviceRemoved is unnecessary - if a device
exists, then it has already passed muster.
SDL2 uses a weird system of device ids and instance ids to report
joystick events, where the ADDED event uses a device id and the rest use
instance ids.
The SDL2 joystick driver is now fixed to correctly distinguish between
the two, which fixes hotplugging support for joystick devices.
SDL GameControllerAxis and GamePadAxes are not interchangeable. The
driver will now correctly interpret incoming SDL messages and update
the GamePadState for the relevant axis.
DummyGLContext will now attempt to load OpenGL and OpenGL ES entry
points when a suitable OpenGL context is current on the calling thread.
This allows OpenTK to be used on contexts created through third-party
toolkits.
CreateGetAddress() constructs a GraphicsContext.GetAddressDelegate that
is suitable for the current platform. This can be used when combining
OpenTK with an OpenGL context created through a third-party toolkit.
The functions defined in libdl.dylib are useful in more places than
just AglContext. Moving them to their own class ensures we can access
these from wherever we might need them.
CGL appears to work with both AGL and NSOpenGL contexts, whereas AGL is
limited to AGL contexts. This allows us to be more flexible in terms of
implementation (i.e. we can use Cgl.GetCurrentContext to retrieve a
handle to a context created through SDL, which uses NSOpenGL
internally.)
When the user requests a GraphicsMode that is not directly supported
by the GPU/drivers, we should relax the requested parameters until
we find a supported mode. An exception should only be thrown when
there is no usable mode.
This makes the X11 backend match the behavior of Windows. The SDL/X11
backend works a little bit differently, in that it falls back to the
a default mode directly if the requested mode is not available. There
is nothing we can do about that.
The _NET_FRAME_EXTENTS atom is implemented differently by
different window managers, when window decorations are hidden
with Motif. Unity returns a 0 size, while Gnome 3 returns the
previous size.
This patch removes that ambiguity: when decorations are hidden,
border size becomes zero. This should work everywhere, unless
some window manager decides to troll us by decorating the window
when we explicitly request no decorations. Sigh...
Windows can now be resized programmatically, even when they have
WindowBorder.Fixed. All resizing logic is now consolidated in the
Bounds property, and ConfigureNotify messages are now handled
correctly depending on their source (StructureNotify or
SubStructureNotify.)
WinMM is optimized for general joystick use, not for the canonical
GamePad layout. Instead of exposing IGamePadDriver directly, it should
expose IJoystickDriver2 and use a mapping driver to get GamePad support.
Without this flag, OpenGL rendering does not work as expected.
Additionally, all WGL_ARB_pixel_format attributes are expected to be
specified in key-value pairs. Fixed double-buffering and stereoscoping
rendering attributes.
Fixed WGL_ARB_pixel_format attribute selection for doublebuffering,
stereoscopic rendering and hardware acceleration. Implemented
minimization strategy to select the optimal PixelFormatDescriptor in the
fallback path.
Instead of creating a list of all available formats and iterating
through that, we let the driver decide which is the best accelerated
format to use for the user parameters. If no such format exists, we fall
back to generic acceleration or software acceleration, in turn.
This affects issue #21
