* Speed up QPixmap::width(), height(), isNull() and depth().Andreas Aardal Hanssen2009-06-171-6/+1
| | | | | | | | | | | | | | | | This change moves the w, h, d variables to QPixmapData and introduces is_null to keep track of nullness. This is possible only because QPixmapData is internal API; otherwise we'd have to be smarter. The optimization makes the QPixmap::width() function take 7 instructions, down from 34 before. For the calculator demo in the declarative ui branch this reduces a block of 750000 instructions (out of 30000000) to around 100000-150000 instructions. Tested on Windows, Linux, Mac. Raster, X11 and OpenGL paint engines. Have not tested the DirectFB engine. Reviewed-by: Trond

* Made QPixmap autotest pass with -graphicssystem openglSamuel Rødal2009-06-121-0/+4
| | | | | | | | | | | | | | The window surface has been modified to track widget deletion to make sure it doesn't try to access the widget's context data after deletion. QGLPixmapData now also uses GL_RGB instead of GL_RGBA when appropriate, and hasAlphaChannel() has been modified in view of this. A number of other issues have been fixed in QGLPixmapData, and the autotest has been modified to use a more lenient pixmap compare function due to off-by-one pixel errors here and there.

* Avoided expensive image upload for GL pixmap backend for QPixmap::fill.Samuel Rødal2009-05-271-1/+11
| | | | | | | In the fill case we can simply set a flag saying the pixmap needs to be filled, and then when painting on the pixmap we start by filling the background using glClear via the existing QGLDrawable::autoFillBackground interface.

* Correctly handle using GL pixmaps that still have an active engine.Samuel Rødal2009-04-171-2/+5
| | | | | | | | | | | | | | | | | In the case where a GL pixmap is used when there it still has an active engine we need to ensure that the pixmap has been flushed from the render FBO first. The newly added QGLPixmapData::copyBackFromRenderFbo() handles this. In addition, because several GL 2 paint engines can be active on the same context at the same time, we can't make any assumptions and need to call the newly added QGL2PaintEngineEx::ensureCreated() in the beginning of any state-dependent paint engine function. QGL2PaintEngineEx::ensureCreated() correctly transfers control to the current engine if a different engine is active. Running lance with -pixmap and -graphicssystem opengl works correctly with the GL pixmap backend now.
* Use FBOs as pixmap backend in GL graphics system.Samuel Rødal2009-04-161-1/+18
| | | | | | | | We now use FBOs to implement render-to-pixmap for the GL pixmap backend. A multisample FBO is used for rendering, and is then blitted onto a non-multisample FBO dynamically bound to the relevant texture. Reviewed-by: Tom
