* Optimized restore() in GL 2 paint engine.Samuel Rødal2009-10-062-19/+46
| | | | | | | Keep track of what state actually changed so we don't have to set all the uniforms as dirty etc. Reviewed-by: Trond
* Changed GL 2 engine render text implementation to use glDepthRange().Samuel Rødal2009-10-062-16/+30
| | | | This frees all the current dependencies on the depth uniform.
* Made depth tested renderText() work after stencil clipping change.Samuel Rødal2009-10-061-7/+10
| | | | Also we should force Raster_A8 glyph format in renderText().
* Added convex polygon optimization to QGL2PaintEngineExPrivate::fill().Samuel Rødal2009-10-061-5/+4
|
* Switched to using stencil instead of depth buffer for clipping.Samuel Rødal2009-10-062-121/+173
| | | | | Based on Aaron Kennedy's patch. All tests are green, but when enabling scissoring UniteClip seems to be broken atm.

* Fixed an assert occuring on X11 when destroying QPixmaps under GL.Trond Kjernåsen2009-10-061-2/+4
| | | | | | | The cleanup code for the QX11PixmapData was called incorrectly for QGLPixmapData. Reviewed-by: Samuel
* Fixed the X11 error output from the demos/boxes demo.Trond Kjernåsen2009-10-061-0/+5
| | | | | | | | | After we started caching the current context internally, it revealed an old bug: when a QGLWidget is reparented under X11, it will get a new window id, but its context will still be bound to the old window, so we need to rebind it. Reviewed-by: Samuel

| | | | | | | | QGLShareContextScope is safer and more reliable than trying to manually detect how and when to temporarily switch contexts. Replace the few remaining instances of context-switching with it. Reviewed-by: trustme

| | | | | | | | | Context resources are per-group, so they should be managed by the group. This should also improve performance of context shutdown slightly by removing QGLSignalProxy::aboutToDestroyContext() signal dispatches to the resources. Reviewed-by: trustme

| | | | | | | | | This is internal API. It's possible to specify a horizontal and vertical scale, rotation, opacity and source rectangle for each pixmap item. Useful for particle effects. Reviewed-by: Trond

| * Fix BadDrawable errors when re-parenting a QGLWidget on X11/EGLTom Cooksey2009-10-011-2/+13
| | | | | | | | | | | | | | | | | | | | It's actually not really reparenting, but calling setWindowFlags which triggered the errors. But setWindowFlags causes a re-parent. The context isn't really the right please to free the surface, but fixing that is a much more intrusive change. Reviewed-By: TrustMe

| * Make QGLFramebufferObject crash-proof if QGLContext destroyed firstRhys Weatherley2009-10-012-26/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes it isn't possible to arrange for the QGLFramebufferObject to be destroyed before the QGLContext group in which it was created. Especially during application shutdown or in applications with multiple shared contexts. This change modifies QGLFramebufferObject to use QGLSharedResourceGuard, which ensures that when the last QGLContext in a sharing group is destroyed, any remaining FBO's will revert to !isValid(). It is now safe to destroy the context before the FBO, or the FBO before the context. Unit test included. Reviewed-by: Sarah Smith
| * Add Qt::RenderHint to control rendering operations.Bjørn Erik Nilsen2009-09-301-9/+9
| | | | | | | | | | | | | | | | | | | | | | We need a way to control various rendering operations. For example, whether quality is more important than performance, or the other way around. This change also replaces occurences of QPixmapFilter/QGraphicsEffect::BlurHint (introduced in 1a431e850893b6b162c833f4f148f090e2427dda) with Qt::RenderHint. Reviewed-by: Samuel

| * Make QPF's implementation of alphaMapForGlyph() consistent.Rhys Weatherley2009-09-291-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The QPF implementation of alphaMapForGlyph() was returning color values of RGBA = (a, a, a, 255) instead of (0, 0, 0, a), which was inconsistent with all the other font engines. This inconsistency caused some QPF-specific workarounds in the OpenGL and OpenVG paint engines. This change removes the workarounds and makes QPF generate the right colors from the start. Paint engines that ignore the color table or which don't use the alphaMapForGlyph() function (e.g. raster) are not affected. Reviewed-by: Paul
| * Fix EGL/GLX surface leak when using texture-from-pixmapTom Cooksey2009-09-291-3/+2
| | | | | | | | | | | | | | | | | | The QScopedPointer changes mean that the pixmap data's reference count is now decremented after the cleanup hooks are called. The hooks should also only be called when the pixmap data gets deleted, so we don't actually have to check the reference count at all. Reviewed-by: TrustMe
| * Use glXGetProcAddress to resolve glx extensionsTom Cooksey2009-09-292-57/+68
| | | | | | | | | | | | | | | | | | | | | | | | On systems where the GL driver is pluggable (like Mesa), we have to use the glXGetProcAddressARB extension to resolve other function pointers as the symbols wont be in the GL library, but rather in a plugin loaded by the GL library. This fix basically makes texture-from-pixmap work on Mesa drivers like intel i915 & friends. Reviewed-by: Trond

| | | | | | | | | | | | Several problems: 1. The demo leaked the scene contents, which caused cleanup problems. 2. The QGLContext::currentContext() could be changed behind Qt's back under Windows (the temp contexts never reset the current context). 3. QGLFormat::openGLVersionFlags() function would return uninitialized flags if the QGLWidget constructor happened to call qt_gl_preferGL2Engine(). Reviewed-by: Kim
