Deactivating Particular keys

[Uttama_vizard]

Hello,

I am using both. At one point of time, I am using viz.callback and another time, I am using onKeyDown function.

Registering key callback....what you suggested is not clear to me. Can you please elaborate a little bit more?

Thanks

Here is some sample code showing how to switch between 2 different keydown callback functions. You can press the 1,2 keys to set which callback to use. Pressing spacebar will print out which callback is currently registered.

import viz
viz.go()

def onKeyDown1(key):
	
	if key == '2':
		viz.callback(viz.KEYDOWN_EVENT,onKeyDown2)
	
	elif key == ' ':
		print 'space pressed in callback 1'
		
def onKeyDown2(key):
	
	if key == '1':
		viz.callback(viz.KEYDOWN_EVENT,onKeyDown1)
	
	elif key == ' ':
		print 'space pressed in callback 2'

viz.callback(viz.KEYDOWN_EVENT,onKeyDown1)
