[Tkinter-discuss] Disabling widgets [especially ttk.Scale]

[Martin B.]

hi all,
i have a little problem with setting state of ttk.Scale widget.

i have a ttk.Checkbutton which operates with ttk.Scale. [enabling,disabling]

<code>

self.check=BooleanVar()
button = ttk.Checkbutton(self, text='',variable=self.var,command=self._setActive) 
self.slider = ttk.Scale(self)

def _setActive(self, event=None):
	if self.check.get():
		self.slider.state(statespec=('active',))
	else:
		self.slider.state(statespec=('disabled',))

</code>

but if i make checkbutton active, slider is disabled :(
how i make Scale state enabled and disabled if
self.slider.config(state=NORMAL) is unknown option.

sry for newbie Q.
thanks
