* Automatically destroy VG pixmaps when the last window surface goes awayRhys Weatherley2009-12-061-2/+29
| | | | | | | | | | | | | | Under S60, Qt will destroy the window surfaces of an application that goes into the background, which frees up EGL surface objects. But the VGImage's for pixmaps, and the EGLContext, were still using GPU memory. This change keeps track of the number of widgets / window surfaces that are in use and then calls hibernate() on all QVGPixmapData objects when it goes to zero. Once all the VGImage's are destroyed, the EGLContext should also be destroyed. Task-number: QT-2555 Reviewed-by: Sarah Smith
* Do not recreate the VGImage if the size is unchangedRhys Weatherley2009-11-201-0/+1
| | | | | | | | | When a pixmap's contents change in QVGPixmapData, only recreate the VGImage in the GPU if the size is different than before. This should help reduce GPU memory fragmentation. Task-number: QT-2504 Reviewed-by: Sarah Smith
* Support OpenVG graphics systems that inherit from QVGPixmapDataRhys Weatherley2009-11-111-3/+3
| | | | | | | | Custom graphics systems, may want to inherit from QVGPixmapData to implement alternative pixmap management strategies. We make toVGImage() overridable and the data members protected to support this. Reviewed-by: Sarah Smith
* Added QPixmapData::createCompatiblePixmapData() used by QPixmap::copy().Samuel Rødal2009-10-141-0/+2

* Modify functions for native pixmap data conversion on Symbian.Jason Barron2009-09-231-2/+2
| | | | | | | | | | | | | We need a way to support converion to and from multiple native pixmap types from multiple pixmap backends. Instead of adding more virtual functions to QPixmapData, make the existing one more generic but pass an opaque pointer and a type and do some internal casting. Currently this function is Symbian only, but could easily be extended to work on other platforms. Reviewed-by: Aleksandar Babic Reviewed-by: Jani Hautakangas
* Adding support for symbian graphics resources.Aleksandar Sasha Babic2009-09-181-1/+13
| | | | | | | | | | | | | | This enables us to convert from and to new Symbian type of graphics resource, namely SgImage. This only supported with the OpenVG graphics system. On other graphics systems this will return null QPixmap. Conflicts: src/corelib/global/qglobal.h src/gui/image/qpixmap.h src/gui/image/qpixmap_s60.cpp Reviewed-by: Jason Barron

* | Another fix for the include bug in Symbian.Jason Barron2009-07-091-1/+1
|/ | | | | | This header is included by the VG graphics system plugin and since that exists in a different module, the header inclusion bug rears its ugly head again and we need to workaround it by making it a system include.
* Integrate the OpenVG graphics system into Qt 4.6Rhys Weatherley2009-06-221-0/+113
This change also moves the EGL support classes from QtOpenGL to QtGui so they can be shared between OpenGL and OpenVG.
