HOM - How to get the button parameter name when the button is pressed.

[djbyun]

Hello,

Does anybody know how to get the button parmeter's name itself using python, when the button is pressed?

Thanks.

The callback field has a kwargs dictionary that contains things like the node and parm objects.

Graham,

I tried to use kwargs['parm_name'] or kwargs['parm'].name(). But they didn't work. The only thing which worked in Python Module was kwargs['type']. Would you mind showing an example code for getting the button parmaters name when I push it?

Thanks.

kwargs shows lots of information for me when printed from the callback field:

{'node': <hou.ObjNode of type null at /obj/null1>, 'script_value0': '1', 'script_value': '1', 'script_multiparm_index': '-1', '
script_multiparm_nesting': '0', 'script_parm': 'myparm', 'parm': <hou.Parm myparm in /obj/null1>, 'parm_name': 'myparm'}

If you are trying to access this information inside a function in the PythonModule, you would need call the function from the callback field and pass kwargs as the function argument. kwargs inside a PythonModule only gives you the node type information, as you've seen.

Graham,

It works pretty well. I could understand more clearly how kwargs works from your example file. I really appreciate it for your help.
