Robert Osfield	39dcea9ebb	From Colin McDonald and Robert Osfield, converted Traits::sharedContext from GraphicsContext* to osg:observer_ptr<GraphicsContext> to prevent dangling pointer issues.	2012-09-05 21:03:41 +00:00

Robert Osfield	ce4890fa7a	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."	2012-02-08 09:34:44 +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	f07a1a91c8	From Claus Scheiblauer, fixed handling of horizontal mouse wheel events.	2011-07-20 10:17:19 +00:00
Robert Osfield	4f7903f732	From Mathias Froehlich, build fixes for legacy unix systems	2011-06-07 14:26:13 +00:00
Robert Osfield	1b6700b4c7	Fixed build error	2011-05-24 10:08:40 +00:00
Robert Osfield	d4eceb0b90	From Wang Rui, added close button hint	2011-05-17 09:21:32 +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
Robert Osfield	0875b19ab8	Fixed traling spaces	2011-05-16 08:59:10 +00:00
Robert Osfield	50366ccb91	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)."	2011-03-11 16:31:01 +00:00
Robert Osfield	9b6e3fbe94	From Andreas Roth, "simple fix to support quad buffer stereo in osgQt"	2011-01-27 18:49:22 +00:00
Robert Osfield	eb9510eb72	Moved GraphicsWindowQt from osgviewerQtContext into osgQt.	2010-12-13 16:25:50 +00:00
