* Remove obsolete OpenGL/ES CommonLite (fixed-point) supportRhys Weatherley2010-02-041-13/+9

* Rework how Qt handles GL extensions.Trond Kjernåsen2010-01-131-4/+3
| | | | | | | | | | | | | | | | | | Qt used to store the GL extensions a particular implementation supported in a global cache, which was initialized once and never updated. This could cause problems because different types of context might support different kinds of extensions (e.g. the difference between sw and hw contexts). With this patch, the GL extensions are cached and updated within each QGLContext. It also makes the extension initialization lazy, which saves application initialization costs for embedded platforms. The patch introduces a internal cross platform QGLTemporaryContext class that is used to create a light-weight GL context without going via QGLWidget and friends (QWS and WinCE still have QGLWidget fallbacks for now).

| * qt_paint_device_metric() for fetching metricsRhys Weatherley2009-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | Custom window surfaces, graphics systems, and Qt/Embedded screen drivers often need to access QPaintDevice::metric(), but it is protected. Hence the growing number of friends in QWidget and QImage. The qt_paint_device_metric() function provides a more future-proof approach that doesn't require lots of friends. Reviewed-by: Gunnar

* | Fixed crash in the Boxes demo when using -graphicssystem opengl.Kim Motoyoshi Kalland2009-10-161-0/+6
|/ | | | | | | | | | QGLWindowSurface::flush() assumed that updateGeometry() had been called, but in some cases it hadn't. It would therefore dereference a null pointer and crash. This has been fixed by returning from flush() if updateGeometry() has not been called. This fixes the symptom rather than the bug, so we still need to find out why it hasn't been called.

* Refactored gl window surface a bit.Gunnar Sletta2009-09-211-37/+43
| | | | | | | | | | | | The logic was a bit messy and didn't work on Mac OS X. On Linux we also had issues with 8xxx nvidia cards which didn't render properly. The FBO is now unbound between calls to beginPaint(), which prevents other gl calls from messing it up, which is probably what was the error in the first place. In addition, on Mac OS X, we also call the upatePaintDevice() as a result of setGeometry() to force-update the dimensions of the context. Reviewed-by: Trond
