osgViewer.GraphicsWindow

class osgViewer.GraphicsWindow
Represents

c++ class

Wraps

osgViewer::GraphicsWindow

Bases

osg.GraphicsContext, osgGA.GUIActionAdapter

Base class for providing Windowing API agnostic access to creating and managing graphics window and events. Note, the osgViewer.GraphicsWindow is subclassed from osg.GraphicsContext, and to provide an implementation you’ll need to implement its range of pure virtual functions, you’ll find these all have naming convention methodNameImplementation(..). osgViewer.GraphicsWindow adds the event queue on top of the osg.GraphicsContext, thereby adding a mechanism for adapting Windowing events as well as basics graphics context work, you should wire up custom GraphicsWindowImplementation to push their events through into the osgGA.EventQueue.

Here is example of getting default GraphicsWindow and setup cursor appearance:
