I am using OSG & osgEarth in my Qt application. When I use ON_DEMAND, it does not always repaint when I would expect it to. The easiest way to describe this would be as follows (I have seen several variations to this, but believe they are all related):
1) Open up the application using osgEarth in ON_DEMAND mode. 2) Wait until no painting is being done. 3) Open up Task Manager and drag it around the application in #1. 4) You will see the task manager window everywhere it was dragged. 5) As soon as the mouse or keyboard causes an update, the view is fixed. It almost seems that somewhere a message is being ignored. Okay, maybe ignored is not the right word . . . handled??? For example, maybe a paintEvent is triggered in Qt because of a rectangle or region has become invalid. I found a way to fix this by forcing frame() to be called if the rect() is different than the graphics window. Is there a more elegant way of doing this??? Is this actually a bug in OSG or osgEarth? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44077#44077 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
