Mouse event: how to detect no mouse move event, how to set mouse position?

[farshizzo]

You can use a delayed timer to detect when the mouse stops moving after a certain amount of time. The following script shows how to do this:

import viz
viz.go()

MOUSE_STILL_EVENT = viz.getEventID('MouseStillEvent')

class MouseStillHandler(viz.EventClass):
	def __init__(self,delay=0.25):
		viz.EventClass.__init__(self)
		self.still_delay = delay

		self.callback(viz.TIMER_EVENT,self._onTimer)
		self.callback(viz.MOUSE_MOVE_EVENT,self._onMouseMove)

	def _onTimer(self,num):
		viz.sendEvent(MOUSE_STILL_EVENT,viz.Event(delay=self.still_delay))
		self.killtimer(0)

	def _onMouseMove(self,e):
		self.killtimer(0)
		self.starttimer(0,self.still_delay)


handler = MouseStillHandler()

def onMouseStill(e):
	print 'Mouse still'

viz.callback(MOUSE_STILL_EVENT,onMouseStill)

Thank you farshizzo, the script works well, though I do not really understand the codes.

Is that the MOUSE_STILL_EVENT is a variable you create, while the 'MouseStillEvent' is a constant defined somewhere else?

Sorry for the newbie question.

The viz.getEventID function is used to generate a custom event ID given a unique event name.
