Triggers the OnUpdate event
Source position: classesh.inc line 1446
public function TBasicAction.Update: Boolean; virtual; |
Update triggers the OnUpdate event, if one is assigned. It returns True if the event was triggered, or False if no event was assigned.
Application programmers should never run Update directly. The Update method is called automatically by the action mechanism; Normally this is in the Idle time of an application. An application programmer should assign the OnUpdate event, and perform any checks in that handler.
