Upgraded the Win32 backend to work with the multi-stage
subclassing code. * clutter/win32/clutter-stage-win32.h: * clutter/win32/clutter-stage-win32.c: Now inherits from ClutterGroup and implements ClutterStageWindow instead of inheriting directly from ClutterStage. * clutter/win32/clutter-event-win32.c (message_translate): Now takes an extra parameter to return whether DefWindowProc should be called. This is needed to prevent the default WM_CLOSE handler from destroying the window. * clutter/win32/clutter-backend-win32.c (clutter_backend_win32_dispose): Destroy all of the stages using g_slist_foreach as per bug #871. Now also destroys the GL context. (clutter_backend_win32_get_features): Added assertions to ensure there is a valid GL context. (clutter_backend_win32_ensure_context): Accepts NULL stage. Gets implementation pointer from the stage.

Upgraded the Win32 backend to work with the multi-stage
|
||||
subclassing code.
|
||||
|
||||
* clutter/win32/clutter-stage-win32.h:
|
||||
* clutter/win32/clutter-stage-win32.c: Now inherits from
|
||||
ClutterGroup and implements ClutterStageWindow instead of
|
||||
inheriting directly from ClutterStage.
|
||||
|
||||
* clutter/win32/clutter-event-win32.c (message_translate): Now
|
||||
takes an extra parameter to return whether DefWindowProc should be
|
||||
called. This is needed to prevent the default WM_CLOSE handler
|
||||
from destroying the window.
|
||||
|
||||
* clutter/win32/clutter-backend-win32.c
|
||||
(clutter_backend_win32_dispose): Destroy all of the stages using
|
||||
g_slist_foreach as per bug #871. Now also destroys the GL context.
|
||||
(clutter_backend_win32_get_features): Added assertions to ensure
|
||||
there is a valid GL context.
|
||||
(clutter_backend_win32_ensure_context): Accepts NULL stage. Gets
|
||||
implementation pointer from the stage.
