Deriving from DirectButton - how to call __init__?

Scripting Issues
1

Hi all,
is there an obvious reason why DirectGui classes don’t offer any kind of ‘id’ or ‘name’ property – or do they? It’s not that one can’t work around this but I was just wondering …
Which leads to my actual (quite embarassing) question: When I try to derive a class from DirectButton, I don’t get the keyword parameters up to the super class, no matter how hard I try. It always ends up with python complaining about either wrong argument number or wrong argument type. I tried lots of varations of “DirectButton.init” as well as “super” calls. Could anyone help me out here (minimal example below)?

import direct.directbase.DirectStart
from direct.gui.DirectGui import DirectButton
from direct.gui.DirectGui import DirectFrame
from direct.showbase.DirectObject import DirectObject

class World(DirectObject):
	def __init__(self):
		f = DirectFrame()
		b = IDButton(parent=f, text='Hello', scale=.2)

class IDButton(DirectButton):
	def __init__(self, parent = None, **kw):
		#super(IDButton, self).__init__(parent, kw)
		DirectButton.__init__(self, parent, kw)
		self.id = ''

w =	World()
run()

Thank you, Christof.

There are already some threads about this. Search for : initialiseoptions.
DirectGui classes have an ID, which is guiId.

Ok. Now I’m even more embarassed. First I don’t know why I didn’t find one of the threads where this initialiseoptions thing was discussed and second, a brief look in DirectGuiBase would have pointed me to the guiId property. Sorry for bothering you with things I could have easily found out for myself.
Thanks anyway.
