Detailed Description

InteractiveImage is an event handler that computes the mouse coordinates in an images coordinate frame and then passes keyboard and mouse events to it. This event handler is useful for vnc or browser surfaces in the 3D scene.

◆ run()

osg::Object *  data 
)
inlinevirtual

Invoke the callback, first parameter is the Object that the callback is attached to, the second parameter, the data, is typically the NodeVisitor that is invoking the callback. The run(..) method may be overridden by users directly, or if the user is using one of the old style callbacks such as NodeCallback or Drawable::UpdateCallback then you can just override the appropriate callback method on those callback subclasses. If you are implementing your own callback then one should call traverse() to make sure nested callbacks and visitor traversal() is completed.

Reimplemented from osg::Callback.
