| | | | | | | | | Attribute locations must be bound before a shader program is linked according to the GLSL specification. Issue a warning to the user if they do it in the wrong order, which should help to isolate hard to find bugs much quicker. Reviewed-by: trustme

| | | | | | | | | | | | | | | | | | The QGLEngineShaderManager pointers in QGLCustomShaderStagePrivate have been changed to QPointers to prevent the QGLPixmapFilters in QGL2PaintEngineEx from dereferencing the QGLEngineShaderManager after it is destroyed. Reviewed-by: Rhys Weatherley
* | Fixed an assert when running the composition demo on Mac.Trond Kjernåsen2009-10-201-16/+19
| | | | | | | | | | | | | | We can't create a QGLWidget in the QGLEngineSelector, since it may be called before a QApplication object has been constructed. Reviewed-by: Kim

| | | | | | | | | | | | | | QGLTextureCache installs pixmap cleanup hooks which are used to clean up the EGL surfaces. Reviewed-By: Trustme
* | Add a new window surface which utilises QX11GLPixmapDataTom Cooksey2009-10-205-4/+239
| | | | | | | | | | The new surface uses XCopyArea to post updates to the window and thus, supports partial updates.
* | Fixed a stencil clearing bug in the GL 1 engine.Trond Kjernaasen2009-10-201-19/+21
| | | | | | | | | | | | | | | | If the system clip changed the stencil buffer wasn't necessarily updated correctly. Use a region to keep track of the dirty areas in the stencil buffer, like we do in the GL 2 engine. Reviewed-by: Samuel

* | Use different GL contexts for ARGB & RGB pixmapsTom Cooksey2009-10-191-31/+100
| | | | | | | | | | | | | | | | | | On 16 bpp systems, RGB pixmaps are 16-bit whereas ARGB pixmaps are 32-bit. This means two different EGL configs are used which are incompatable with each other. As a result, we have to use 2 different EGL contexts - one for each config. Reviewed-By: Trustme

* | Separate modification & destruction pixmap cleanup hooksTom Cooksey2009-10-192-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | Before the QExplicitlySharedDataPointer change, the ref-count was 0 when calling the cleanup hooks from ~QPixmap. That enabled the hook to figure out if the pixmap is being modified or deleted. As the ref count is now 1 when calling the cleanup hooks in ~QPixmap, we need to seperate the hooks. This change should make using textre-from-pixmap faster as the EGL/glX surface wont get re-created everytime the pixmap is modified. Reviewed-By: Gunnar

| * Recognize transformed screens when looking for a QGLScreenRhys Weatherley2009-10-161-1/+2
| | | | | | | | | | | | | | | | | | | | If the QWS_DISPLAY is specified as "Transformed:powervr:...", then we will encounter QScreen::TransformedClass rather than QScreen::ProxyClass when searching for the QGLScreen. This change makes the code search for both. Task-number: QT-2261 Reviewed-by: Sarah Smith

| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | The qt_qgl_paint_engine() function was being used by QWS, but there's no reason why it can't be used by other platforms too. This should also fix ES 2.0 paint engine support under QWS, which was stubbed out. Reviewed-by: Sarah Smith 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.

| | | | | | | | | | | | | | | | | | When QGLPixmapData is bound after a fill(), without being painted on in the mean-time, it's cheaper to directly generate a source image than to go through convertToGLFormat(), since all the pixels in the image will have the same value. Reviewed-by: Trond

* Optimized rasterizing of paths using stencil method in GL 2 engine.Samuel Rødal2009-10-073-5/+43
| | | | | | | | | | | | Making the triangle fan of each sub path start at the sub path's centroid will on average improve performance for complex paths, because less pixels that are outside the path need to be touched. The centroid is a more balanced choice than just picking the first element of the sub path as triangle fan origin. A performance improvement of 20 % was measured for star formed paths.

When stencil clip is set, the number of compositing passes is reduced from five to four. For clipping with a winding fill path, the number of compositing passes are reduced from five to four when stencil clipping is already enabled. A performance improvement of up to 85 % was measured in certain cases. Reviewed-by: Trond
