onMouseDrag()

Method that is called when the mouse drags an element. Dragging refers to pressing a mouse button down over an element and moving the mouse while still having the button pressed down. This event handler method is fired in sprites and tags when the mouse is dragged from over an element's content (whatever is drawn in the element's onDraw()). Events for sprites and tags have to be enabled when needed by calling enableMouseEvents() on the element.

class ASprite(Sprite):
    def onMouseDrag(self, event):
    	pass

class ATag(Tag):
    def onMouseDrag(self, event):
    	pass
