Message:

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."
