From Juan Manuel Alvarez, "When handling keyboard events on osgQt, if a key is kept pressed, multiple sequences of KEYDOWN -> KEYUP events are fired.
...
This is because Qt auto repeats keyboard events, so multiple calls are made to GLWidget::keyPressEvent and GLWidget::keyReleaseEvent by Qt, and subsequently translated to OSG events.
The way to solve this is ignoring key released auto repeated events (see http://qt-project.org/doc/qt-4.8/qkeyevent.html#isAutoRepeat ), so multiple KEYDOWN events are fired, but only one KEYUP.
I attach a modified osgQt/GraphicsWindowQt.cpp with this change."

Introduced new scheme for handling mouse events with osgViewer. The new scheme enables robust event handling even when using distortion correction render to texture Cameras.

From Colin McDonald and Robert Osfield, converted Traits::sharedContext from GraphicsContext* to osg:observer_ptr<GraphicsContext> to prevent dangling pointer issues.

From Claus Scheiblauer, "in GraphicsWindowQt.cpp the GLWidget::keyReleaseEvent was implemented slightly different to the GLWidget::keyPressEvent, which caused the cursor keys values to be not correctly mapped from an QKeyEvent value to an osg key value when releasing a cursor key."

From Robert Milharcic, "This will hopefully fix some issues with osgQt, more precisely with GLWidget event handling. There are at least two current GL context braking events, QEvent::Hide and QEvent::ParentChange. When running in a multithreaded mode they both try to change current GL context in a wrong thread (main GUI thread). The QEvent::ParentChange is also problematic when running in a single threaded model because Qt is going to release current contex then delete it, and then it will create new one, and as a result the osg will continue to render to an invalid deleted context. This changes workaround above problems by deferring execution of the problematic evens. These events has to be enqueued and executed later. The enqueued event processing is currently done right after swap in a swapBuffersImplementation of GraphicsWindowQt while code is running in a render thread by calling QGLWidget handler directly. In principle the deferred events queue should be executed while in GUI thread but I couldn't find any reliable way to do this, that is without risking a deadlock. For now it is assumed, Qt is not going to execute any GUI thread only operations inside the QGLWidget handler."

From Jan Peciva, I have improved GraphicsWindowQt:
...
- renamed osgQt::GraphWidget to osgQt::GLWidget
as it better fits to Qt naming (osgQt::GLWidget is derived from QGLWidget
while recent GraphWidget... it is unclear, maybe QGraphicsView,
QGraphicsScene,....)
- added the code to properly manage ON_DEMAND rendering scheme
(involves osgQt::setViewer() and internal HeartBeat class)
- added forward key events functionality. It allows to not eat the key events
by GLWidget, but it forwards them to Qt processing as well.
- destroying GLWidget before GraphicsWindowQt and vice versa does not crash
the application
- it is possible to request particular QGLFormat in GLWidget constructor
- added QtWindowingSystem class
- multithread OSG rendering improvements/fixes

From Benjamin Wasty and David Guthrie, "currently, non-alpha-numeric keys are not recognized (except as modifiers) in osgQt, so I added the mapping code from my Qt integration to GraphicsWindowQt (which is based on Delta3D code from David Guthrie - he gave me permission to submit it under OSGPL)."
