Remarks

This class provides Open Inventor rendering and message handling inside a Windows window. There is a routine to specify the scene to render. The scene is automatically rendered whenever anything under it changes (a data sensor is attached to the root of the scene), unless explicitly told not to do so (manual redraws). Users can also set Open Inventor rendering attributes such as the transparency algorithm, antialiasing on or off, etc. This class employs an OIV.Inventor.SoSceneManager to manage rendering and message handling.

Windows messages that occur in the render area can be handled by the application, by the viewer (if this is really a viewer), or by the nodes in the scene graph. When a message occurs, it is first passed to the application message delegate function registered with the setEventCallback() method on OIV.Inventor.Win.SoWinRenderArea. If this function does not exist or returns false, the message is either used directly by the viewer or translated to an OIV.Inventor.Events.SoEvent for further scene graph processing. If the viewer does not handle the message, the OIV.Inventor.Events.SoEvent is sent to the scene graph by way of an OIV.Inventor.Actions.SoHandleEventAction.
