// CLASS: MDrawRequestQueue
|
|
//
|
|
// This class defines a simple interface for a collection of
|
|
// MDrawRequest objects.
|
|
//
|
|
// An MDrawRequestQueue object is passed to the getDrawRequests method
|
|
// of a user defined shape's UI class (MPxSurfaceShapeUI).
|
|
// This queue keeps track of all the things that need to get draw
|
|
// when a refresh of the view occurs.
|
|
//
|
|
// Maya will call the getDrawRequest methods of all the visible DAG objects
|
|
// before a refresh happens. Then as the refresh happens, each draw request
|
|
// will be processed and the corresponding draw method for each DAG
|
|
// object will get called. For user defined shapes MPxSurfaceShapeUI::draw
|
|
// will get called.
|
