* Implement Texture-From-Pixmap using EGLImage extensions on X11/EGLTom Cooksey2010-03-261-35/+111
| | | | | | | | | | | | | | | | | | | | | | There's lots of EGLImage extensions, split between EGL and client rendering APIs like OpenGL ES & OpenVG. To implement texture-from- pixmap using EGLImage, both EGL extensions and OpenGL ES extensions are needed. This patch resolves the EGL extension function pointers after the display is initialized in QEgl::display(). These are then exported from QtGui so they can be used in QtOpenGL. The OpenGL ES extension function pointers are resolved using the usual qglextensions.cpp mechanism. Using EGLImage seems to remove a fixed ~10 millisecond overhead per pixmap bind when compared to using EGLSurface. Exact results per bind for 100 QPixmaps are: 8x8 Pixmap: 12 -> 1.71 msecs (EGLSurface -> EGLImage) 64x64 Pixmap: 11.6 -> 1.83 msecs (EGLSurface -> EGLImage) 128x128 Pixmap: 12.8 -> 2.74 msecs (EGLSurface -> EGLImage) 256x256 Pixmap: 16 -> 6.20 msecs (EGLSurface -> EGLImage) Reviewed-By: Trond
* Delete the QGLContext in ~QX11GLPixmapDataTom Cooksey2010-03-111-0/+1
| | | | | | | | This also includes changes which allow QGLContext to not own it's own QEglContext. With X11GL, the QEglContext gets reused by multiple QGLContexts so it is important QGLContext doesn't delete it. Reviewed-By: TrustMe

* Make sure 16-bit EGL configs are chosen over 32-bit configsTom Cooksey2010-03-101-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to make sure 16-bit configs are chosen over 32-bit configs as they will provide the best performance. The EGL config selection algorithm is a bit stange in this regard: The selection criteria for EGL_BUFFER_SIZE is "AtLeast", so we can't use it to discard 32-bit configs completely from the selection. So it then comes to the sorting algorithm. The red/green/blue sizes have a sort priority of 3, so they are sorted by first. The sort order is special and described as "by larger _total_ number of color bits.". So EGL will put 32-bit configs in the list before the 16-bit configs. However, the spec also goes on to say "If the requested number of bits in attrib_list for a particular component is 0, then the number of bits for that component is not considered". This part of the spec also seems to imply that setting the red/green/blue bits to zero means none of the components are considered and EGL disregards the entire sorting rule. It then looks to the next highest priority rule, which is EGL_BUFFER_SIZE. Despite the selection criteria being "AtLeast" for EGL_BUFFER_SIZE, it's sort order is "smaller" meaning 16-bit configs are put in the list before 32-bit configs. So, to make sure 16-bit is preffered over 32-bit, we must set the red/green/blue sizes to zero. This has an unfortunate consequence that if the application sets the red/green/blue size to 5/6/5 on the QGLFormat, they will probably get a 32-bit config, even when there's an RGB565 config avaliable. Oh well. Reviewed-By: TrustMe

* Add and use QGLContextPrivate::eglSurfaceForDevice()Tom Cooksey2010-03-021-1/+1
| | | | | | | | | The QGLContext only stores the EGLSurface for QWidgets & QGLWidgets, other device types like QPixmap & QGLPixelBuffer store the surface themsselves. With this patch it is possible to create a QGLContext on a QPixmap, make it current and render GL to that QPixmap on X11. Reviewed-By: TrustMe

* Move QGLWidget::setContext logic into QEgl & QGLContextTom Cooksey2010-03-021-118/+55
| | | | | | | | | | | | | | | | QEgl::createSurface() on X11 will now check to see if the device's X11 Visual is compatible with the EGLConfig passed in. If it is not compatible, the function will re-create the QPaintDevice's native drawable with a different Visual (one which is compatable with the EGLConfig). This represented the bulk of the QGLWidget::setContext method which is now much simpler. As a consequense of this change, QWidgets with graphicssystem opengl will behave much more like QGLWidget as most of the code is re-used. So things like WA_TranslucentBackground should now work with opengl graphicssystem too. Reviewed-By: TrustMe

* Rework how Qt handles GL extensions.Trond Kjernåsen2010-01-131-102/+92
| | | | | | | | | | | | | | | | | | 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).
