Controller::UpdateController

Performs any processing that must be done before the node to which a controller is attached is rendered.

virtual void UpdateController(void);

The UpdateController function is called when a controller has been invalidated and its target node is about to be rendered. This gives the controller an opportunity to perform any calculations that could be deferred until its target node actually became visible.

Any override of the UpdateController function should always call the base class counterpart to clear the update flag.
