self.PandaFrameBookButton = []

def clickBook(self, event):
	for button in self.PandaFrameBookButton:
		button.setFrameColor(0.3,0.3,0.3,0.0)
	self.PandaFrameBookButton[event].setFrameColor(0.3,0.3,0.3,0.3)

When I run it:

  File "CharacterEditor.py", line 280, in __init__
    command=self.clickBook,extraArgs=[0],relief=1,text_align=TextNode.ALeft,pos=(-1.3,0,0.6),text = '身体'))
  File "/usr/share/panda3d/direct/gui/DirectRadioButton.py", line 90, in __init__
    self.check()
  File "/usr/share/panda3d/direct/gui/DirectRadioButton.py", line 206, in check
    apply(self['command'], self['extraArgs'])
  File "CharacterEditor.py", line 408, in clickBook
    self.PandaFrameBookButton[event].setFrameColor(0.3,0.3,0.3,0.3)
IndexError: list index out of range

When the PandaFrameBookButton be created, the clickBook be runed automated. Why?

By the way, I use panda3d1.8_1.8.0+cvs20120124~natty230_amd64.deb.

This is the way the DirectRadioButton works: it calls its own click() function in its constructor, to ensure the button is initially in the click state.

Your handler function will have to deal with this somehow.

Thank you. Now I use DirectButton instead of DirectRadioButton.
