| * Fixed querying of GLX extensions under X11.Trond Kjernåsen2009-11-161-13/+14
| | | | | | | | | | | | | | | | | | | | | | We always queried the client for its GLX extensions and used them blindly, even though they might not be available in the server. Also fixed the extension string check itself. We used simple sub-string search, which could potentially break if one extension name is a sub-string of another. Task-number: QTBUG-5732 Reviewed-by: Kim
| * Fixed extension checks and usage of the GL 2 engine on old X11 systems.Trond Kjernåsen2009-11-162-25/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression from 4.5, where exporting a GL capable display from an old X11 HP/Sun workstation to a modern Linux machine causes crashes and lots of X11 error output. Just relying on the client GL version number is not enough under X11, since the server might only support GL 1.1 with non or very few extensions. Also, the extension checks worked a bit randomly since it checked for sub-strings which might or might not occur within one or more full extension names. Task-number: QTBUG-5853 Reviewed-by: Kim

* | Make isSharing() reset to false when context no longer sharingRhys Weatherley2009-11-152-1/+2
| | | | | | | | | | | | | | | | | | | | The documentation for QGLContext::isSharing() indicates that the function returns true only when the context is sharing. However, previously the sharing flag would stay on if the context was created as sharing but is no longer sharing. Task-number: QTBUG-5578 Reviewed-by: Sarah Smith
* | Fixed stroking of cosmetic dashed pens with the GL2 paint engine.Kim Motoyoshi Kalland2009-11-131-6/+3

* | Fixed stroking of discontinuous paths with the GL2 engine.Kim Motoyoshi Kalland2009-11-132-4/+3
| | | | | | | | | | | | | | | | | | | | Since the stroke is rendered as a triangle strip, zero area triangles must be inserted in order to have gaps in the stroke. This is achieved by duplicating vertices before and after each gap. It was already done for open subpaths. This commit fixes gaps between closed subpaths. Task-number: QTBUG-5736 Reviewed-by: Gunnar

| | | | | | | | | | | | | | | | | | | | | | | | * 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.

* | Detect context sharing on EGL systemsRhys Weatherley2009-11-093-0/+3
|/ | | | | | | | Context sharing was enabled on EGL systems, but QGLContext::isSharing() was still returning false because the flag in QGLContextPrivate was not updated. Reviewed-by: Sarah Smith
* 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
