Robert Osfield	06f7fd4f48	From Marius Kintel, "GraphicsWindowQt::WindowData no longer requires the parent widget of a graphics window to be of type GLWidget."	2012-02-07 11:41:20 +00:00
Robert Osfield	64fa6aec43	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."	2011-09-13 11:09:39 +00:00
Robert Osfield	a287d85585	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 Robert Osfield, added back in getGraphWidget() method for backwards compatibility.	2011-05-16 09:06:06 +00:00
