* Consistently use QGLShareContextScope for context switchingRhys Weatherley2009-10-054-63/+45
| | | | | | | | 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

| * 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

Also use the fast blur when the radius is 5 or below, as the quality difference is insignificant. Reviewed-by: Rhys Weatherley

* Optimized GL2 engine to use scissor clipping more aggressively.Samuel Rødal2009-09-212-95/+72
| | | | | | | | | | | | | | | | There's no reason to stop using a scissor clip when a more complex clip is set. Instead, we can use a combination of scissoring and depth clipping to represent the final clip. When intersecting with a new clip path, if the clip path is a rectangle we simply intersect it against the scissor clip, and otherwise we intersect its bounding rect against the scissor clip and write the actual path to the depth buffer. The patch simplifies the logic in clip() quite a bit, except in the UniteClip case in which we don't care about performance anyways. It also fixes a bug which could cause rendering errors if the stencil buffer contains junk before painting. Reviewed-by: Gunnar Sletta
