* Fix composition for windows with alphaLaszlo Agocs2014-08-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | While we will cover the entire surface with our textured quads, the clear is still necessary in order to make top-levels with TranslucentBackground render correctly: We don't want to blend transparent areas with undefined content that is in the surface's framebuffer. Blending is problematic for alpha values. We now prevent the blended alpha from being written out. This ensures that in examples like qquickviewcomparison, where the backingstore image contains an alpha of 0.5 while the QQuickWidget texture 1.0, the result is still an alpha value of 1.0 in the final image. Writing out an alpha of 0.5 would break on systems where windows get an alpha buffer by default. hellogl2 can now take a --transparent parameter which makes the QOpenGLWidget being cleared to transparent in order to verify it works in combination with Qt::WA_TranslucentBackground. The swapped red and blue problem is also corrected. RGBA8888 does not need swizzling. The only format that needs this is RGB32.

* Make QOpenGLWidget publicLaszlo Agocs2014-08-011-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | QOpenGLWidget is now public. In addition Qt::WA_AlwaysStackOnTop is introduced to support the special case of semi-transparent QOpenGLWidget or QQuickWidget on top of regular widgets. hellogl_es2 becomes the qopenglwidget example. This example performs painting both via QPainter and native GL commands and has the OpenGL widget combined with other, normal widgets. The widget stack receives some changes when it comes to renderToTexture widgets like QQuickWidget and QOpenGLWidget. Calling update() will now result in a paint event, which is essential for QOpenGLWidget since we want it to behave like a regular widget. The dirty region handling is extended specially for such widgets due to performance reasons. (an OpenGL content update must not result in any backingstore painting, and is thus handled as a different kind of dirtiness) [ChangeLog] Added QOpenGLWidget. This widget serves as a replacement for QGLWidget.

* Use RGBA8888 always in the eglfs backingstoreLaszlo Agocs2014-07-091-8/+1
| | | | | | | | | | | Do not try to be clever, this format works always. Using RGBX8888 for windows without alpha buffer was a bad idea because it broke renderToTexture widgets (QQuickWidget, QOpenGLWidget) which failed to properly draw the transparent rect with this format.

| | | | | | | | | Uploading the pixel data for the entire window on every update is not nice. Not sure why the line in question was added, it is most likely a leftover from some debugging session.

* eglfs: Move reusable functionality to eglconvenienceLaszlo Agocs2014-01-171-0/+187
The cursor implementation is generic GL(ES) code that should be shared by all the present and future egl-based embedded platform plugins. Follow the pattern of QEGLPlatformContext and move this class into eglconvenience as QEGLPlatformCursor. Similarly, the common bits from the context implementation context are moved back to EGLPlatformContext. eglconvenience has now base classes for integration, screen, window, etc. too. By using these, eglfs becomes much smaller and cleaner. This also paves the way for creating new, separate EGL-based platform plugins for Android, embedded Linux, etc. Also added some documentation to each of the base classes. devicediscovery is now fixed to be usable on any platform. The implementation in this case is naturally a dummy one. This finally allows using it from anywhere without myriads of ugly ifdefs.
