button strip get selected button values

[shadowst17]

Hi guys,

I've got a button strip with multi selection. How can I get which items are selected in python? Evaluating the parameter adds them all up into a single number. 

 

Any help would be appreciated.

Hi Dominic,
it is called bitfield, here is the description how to use it:

Another example: I have a Button strip, the Callback script I have:
hou.phm().strip_to_tokens(kwargs['parm'], kwargs['node'])

Then in scripts, PythonModule:

def strip_to_tokens(parm, node):
    bitfield = parm.eval()
    tokens = parm.parmTemplate().menuItems()
    pitch_tuple = [token for n, token in enumerate(tokens) if bitfield & (1 << n)]
    
    pitch_tuple_string = ' '.join(  (map( str , pitch_tuple ) )  )
    node.parm("enable_pitches_tuple").set(pitch_tuple_string)
