* Workaround to VideoCore III scissor bug.Jani Hautakangas2011-10-191-0/+2
| | | | | | | | | | Some versions of VideoCore III drivers seem to pollute and use stencil buffer when using glScissors. Workaround is to clear stencil buffer before disabling scissoring. Task-number: QT-5308 Reviewed-by: Samuel Rødal
* Fix to QGLWidget crashJani Hautakangas2011-10-181-0/+2
| | | | | | | | | | | QGLWidget crashed due to regression caused by fix to QTTH-1553. Crash only occurred if application was locked to landscape mode but started when device was in portrait mode. Task-number: QTTH-1597 Reviewed-by: Laszlo Agocs

* Simplify texture pooling logic in GL graphics system.Jani Hautakangas2011-06-091-1/+26
| | | | | | | | | | | | | Remove ugly TemporarilyCachedBindOption and use QGLTexture objects as texture pool entries instead of QGLPixmapData. Make texture pooling totally Symbian specific, remove VG like texture pooling code and use common texture binding path which is used on other platforms also on Symbian. QGLPixmapData should be only used to bind SgImage based textures (will be implemented by another commit). Task-number: QTBUG-19180 Reviewed-by: Samuel Rødal

* Add work around for bug when painting w/glTexSubImage into large textureEskil Abrahamsen Blomfeldt2010-12-161-0/+1
| | | | | | | | | | | | | | It seems that copying small rectangles from glTexSubImage2D into a texture which is 2048x2048 is busted on some SGX drivers, even though the driver reports 2048 as the maximum texture size. This caused text to turn into flickering garbage once the texture glyph cache had grown to its max size (e.g. when painting very many Chinese glyphs.) To work around the problem, we hardcore the maximum texture height to 1024 on this driver so that the texture glyph cache is reset whenever that size is exceeded.

* Fixed crash when destroying QGLWidgetThorbjørn Lindeijer2010-11-171-1/+2
| | | | | | | | | The QGLWidget destroys the QGLContext, which in turn destroys the bound pixmap. When this happens there may not be a current QGLContext, so check that before trying to restore it. Done-with: Gunnar Sletta Reviewed-by: Samuel
* Prevented race condition on texture destruction.Samuel Rødal2010-11-081-10/+20
| | | | | | | | | | | | When texture destruction was triggered from a different thread, we posted a signal to the QGLSignalProxy. However, before the signal is delivered the corresponding QGLContext might be destroyed in the main thread. We need to post a signal to a QObject which is destroyed when the QGLContext is destroyed instead, to prevent trying to access an invalid QGLContext pointer.

* Prevented threading related crash in OpenGL module.Samuel Rødal2010-10-291-23/+45
| | | | | | | | | | | | If the last shallow copy of a QImage which is cached in the QGLTextureCache is destroyed in a thread at the same time as the QGLContext which the texture was initialized in is active in a different thread, the QImage thread incorrectly tries to make the context active in two threads at once. To prevent this from happening it's best to always do the texture clean-up in the main thread. Task-number: QT-4238 Reviewed-by: Eskil Abrahamsen Blomfeldt
* Added support for blitting to native child widgets in GL window surface.Samuel Rødal2010-10-221-1/+1
| | | | | | | | Support blitting by copying from the top-level window's back buffer to a temporary texture and then blitting from the texture to the native child widget. Performance suffers, but it's better than failing. Reviewed-by: Gunnar Sletta
* Fix GL_OES_element_index_uint and add GL_OES_depth24 detection.Jani Hautakangas2010-10-201-1/+3
| | | | | | | | | GL_OES_element_index_uint detection was not working because EGL config wasn't yet resolved. In addition QFrameBufferObject should use 24bit depth render buffer if extension is available. Task-number: QTBUG-14542 Reviewed-by: Gunnar

* Don't disable texture_from_pixmap on GLX/X11 by default.Trond Kjernåsen2010-09-271-0/+3
| | | | | | | | | | | | | | We made a mistake of trying to make use of the texture_from_pixmap extension by default when binding textures in Qt. The extension have several limitation and using it produces crashes with certain drivers/graphic card combos, but we can't change this now since it will break existing apps using well behaved drivers. We'll fix this for 4.8 with either a QGL::BindOption or configure flag. Revert "Don't try to use the texture_from_pixmap extension in GL on desktop/X11." This reverts commit 07c5429d5aacab932cd912e66287d66fb952e7c4.

| | | | | | | | | There are far too many problems with this extension for it to be usable on desktop at the moment, so disable on desktop GL for now. It's still enabled for EGL, where it seems to have better driver support. Task-number: related to QTBUG-11158 Reviewed-by: Samuel

* | Support building with desktop OpenGL managed via EGLTom Cooksey2010-04-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mostly replaces lots of QT_OPENGL_ES defines with QT_NO_EGL instead. It also switches off EGL auto-detection by default. This is to make sure we default to using GLX on systems with both EGL and desktop OpenGL. If -opengl es1|es2 or -openvg is specified, then EGL auto-detection is switched back on (as a requirement. If configure auto-detects OpenGL ES it also switches on EGL auto-detection, but failue then just disables both EGL & OpenGL. As a side effect, this patch also fixes building Qt when both EGL and glx are avaliable, as they are in Mesa >= 7.8.0. Reviewed-by: Trond Task-number: QTBUG-9691
