un terco problema

[iozk]

este problema me sale cada vez que intento ponerle o acomodarle el codigo

Traceback (most recent call last):
File "C:\pnt.py", line 303, in ?
frame=SketchFrame(None)
File "C:\pnt.py", line 168, in __init__
self.createPanel()
File "C:\pnt.py", line 172, in createPanel
controlPanel = ControlPanel(self, -1, self.sketch)
File "C:\pnt.py", line 15, in __init__
colorGrid = self.createColorGrid(parent, buttonSize)
File "C:\pnt.py", line 25, in createColorGrid
b = (buttons.GenBitmapToggleButton(self, -1, bmp, size=buttonSize))
AttributeError: 'tuple' object has no attribute 'GenBitmapToggleButton'

no veo que pueda ser del codigo siguiente
