* Fix composition for windows with alphaLaszlo Agocs2014-08-131-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Agocs2014-08-011-29/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix issue where revealed widget children do not receive paint event.Chris Colbert2014-03-041-2/+2
| | | | | | | | | | | | | | | | | | | | When a child of a widget is spontaneously revealed due to a call to the parent 'resize' method, the child will not receive a paint event if it has the WA_StaticContents and WA_OpaquePaintEvent flags set. This is caused by the backing store being pre-emptively resized by the call to setGeometry_sys, which causes QWidgetBackingStore::sync to skip the block which handles the static contents. There doesn't appear to be any reason to preemptively resize the backing store, since it is always resized as-needed during the the 'sync' method. This change-set removes the code which preemptively resizes the backing store.

* | Got rid of Map / Unmap events in favor of Expose event.Samuel Rødal2012-03-221-23/+4
|/ | | | | | | | | | | | | | | | | | Since change 2e4d8f67a871f2033 the need for Map and Unmap events has gone away, as now the Expose event is used to notify the application about when it can start rendering. The Map and Unmap events weren't really used except by QWidget to set the WA_Mapped flag, which we now set based on the expose / unexpose. Also guarantee that a Resize event is always sent before the first Expose, by re-introducing an asynchronous expose event handler. Since an expose is required before rendering to a QWindow, show a warning if QOpenGLContext::swapBuffers() or QBackingStore::flush() if called on a window that has not received its first expose.
