unset onkeydown for a key?

[IGoudt]

You can use:

viz.callback(viz.KEYDOWN_EVENT,None)

I guess you can also use:

vizact.onkeydown(key, None)

Depending if you use vizact or viz.callback to handle your events.

Thanks so far...

The space bar should only be pressed once in my experiment:

vizact.onkeydown(' ', play_first_joke)

As soon as it's been pressed, it shouldn't invode the play_first_joke method anymore.

vizact.onkeydown(' ', None)

...gives the following error:

Traceback (most recent call last):
  File "C:\Programme\WorldViz\Vizard30\python\vizact.py", line 3019, in __onkeydown
    self._callGroup(self.__keydownmap[key])
  File "C:\Programme\WorldViz\Vizard30\python\vizact.py", line 2971, in _callGroup
    val = e.call(arg)
  File "C:\Programme\WorldViz\Vizard30\python\vizact.py", line 2794, in _callStatic
    return func(*args,**kwargs)
TypeError: 'NoneType' object is not callable

After searching in the documentation I found the following:

<vizact>.removeEvent
Deletes an EventFunction object

<vizact>.removeEvent( eventFunctionObj )

eventFunctionObj

Remarks

Uses this when you no longer need an EventFunction callback.

Return Value

None

Example

eventFunction = vizact.onupdate( 5, doSomething )
...
vizact.removeEvent( eventFunction )
