Hi,

Does anyone know how I can get current parm on Callback Script? Doesn't look hou.evaluatingParm() works on Callback. And I don't wanna specify the parameter name like hou.pdw().parm(“something”)

for example, I just want to print current value whenever the parameter changed or printing button name when I press the button.


Thanks,
Ryoji

This works for me.
def btnClick (passedData):
    n =  hou.node("/obj/pythonscript1")
    if n:
        p = n.parm("btn_example")
        print dir(p)
        print p.name()
        print p.description() # This is the button caption.

Here is the callback code. Remember to switch from Hscript to Python.
exec(hou.node("/obj/pythonscript1").parm('python').eval());btnClick("")

Hi,
