Hi osg users,
I recently found something strange with osgQT, when a key release event is
added to the event queue the key value is always 0.
It seems to be related to the void GLWidget::keyReleaseEvent( QKeyEvent*
event ) function in the osgQT/GraphicsWindowQt.cpp file.
On key press the QKeyEvent is remaped to get the proper key value but not
in the key release event.
The code is :
void GLWidget::keyReleaseEvent( QKeyEvent* event )
{
setKeyboardModifiers( event );
_gw->getEventQueue()->keyRelease( (osgGA::GUIEventAdapter::KeySymbol)
*(event->text().toAscii().data()) );
// this passes the event to the regular Qt key event processing,
// among others, it closes popup windows on ESC and forwards the event
to the parent widgets
if( _forwardKeyEvents )
inherited::keyReleaseEvent( event );
}
But it should be :
void GLWidget::keyReleaseEvent( QKeyEvent* event )
{
setKeyboardModifiers( event );
int value = s_QtKeyboardMap.remapKey( event );
_gw->getEventQueue()->keyRelease( value );
// this passes the event to the regular Qt key event processing,
// among others, it closes popup windows on ESC and forwards the event
to the parent widgets
if( _forwardKeyEvents )
inherited::keyReleaseEvent( event );
}
I made the fix on my version of the file and it works great.
I'm using OSG 3.0.1 and QT 4.8.0.
Kind regards,
