* Improvements to graphics effects API after review round.Samuel Rødal2009-11-103-29/+29
| | | | | | | | | | | | * Get rid of QGraphicsEffectSource from the public API, instead add convenience functions in QGraphicsEffect. This way we commit to less API, and are free to introduce a customizable QGraphicsEffectSource in a future release. * Move PixmapPadMode into QGraphicsEffect and tweak the names of the enum values. * Make QGraphicsBlurEffect::BlurHint into a bit flag, for extensibility.

* API review: Rename numRects() -> rectCount()Marius Storm-Olsen2009-11-091-1/+1
| | | | | | | QRegion::numRects() is marked obsolete. Removed all usage of the old function inside Qt and test-cases. Reviewed-by: Andreas Aardal Hanssen
* API review: Rename functions numColors(), setNumColors() and numBytes()Marius Storm-Olsen2009-11-062-2/+2
| | | | | | | | | | QPaintDevice and QImage used the functions numColors(), setNumColors(), and numBytes(). However, this is not consistent with the rest of the Qt API which uses *Count() and set*Count(). Removed all usage of these functions inside Qt and test-cases. Reviewed-by: Andreas Aardal Hanssen
* Fix fuzzy aliased rendering on GLES2Tom Cooksey2009-11-062-2/+13
| | | | | | | | | | The GL2 paint engine adds a (0.49,0.49) pixel offset when doing aliased rendering. But this assumed if it was doing aliased rendering then multisampling was disabled. On GLES, multisampling is always enabled if the surface has it enabled. So on GLES, we never add the offset if the surface is multisampled. Reviewed-By: Gunnar

| | | | | | | | | | | | | | | | | | | | | | | | | | | | introduce QMAKE_LIBS_OPENGL_ES1, QMAKE_LIBS_OPENGL_ES1CL and QMAKE_LIBS_OPENGL_ES2 so we do not have to force users to copy/paste around entire mkspecs just to change the OpenGL backend. This should make the "-opengl es2" (and friends) configure option work out of the box with any mkspec on Linux+WinCE. Also removes a WinCE specific hack that is not required anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error message come from the QGLContextPrivate::bindTexture. But since OpenGl errors are retains until glGetError is called the actual error was happening somewhere else. After adding in all the gl* call a check for a gl error, I was able to get the place where opengl fail with a GL_INVALID_ENUM.
