stopping tkinter callbacks

[Mike Fletcher]

You might try using a threading.Lock() ?  That is:


def OnClick( self, event ):
	if self.buildingWhateverLock.acquire( blocking=0 ):
		# build here, you have the building lock
		# make sure you call this when done!
		self.buildingWhateverLock.release()
	else:
		# ignore here, you don't have the lock
		# possibly give some sort of "patience already"
		# feedback (maybe make a sound, or whatever)

See documentation on the threading module for more info.

HTH,
Mike
