* @brief platform independent render window
|
|
*
|
|
*
|
|
* vtkGenericOpenGLRenderWindow provides a skeleton for implementing a render window
|
|
* using one's own OpenGL context and drawable.
|
|
* To be effective, one must register an observer for WindowMakeCurrentEvent,
|
|
* WindowIsCurrentEvent and WindowFrameEvent. When this class sends a WindowIsCurrentEvent,
|
|
* the call data is an bool* which one can use to return whether the context is current.
