Howto apply a sensitive state to a checkbutton?

["Andreas Fey" <Andreas Fey t-online de>]

Hi GTK-Fans,

I have written my first GTK-1.2 application.
All thing works fine except on little design behavior. I want to grey out
some widgets to signal the user that they are not active. So I found the
senstivie property which is exactly that what I wanted.
But on my checkbutton-widget it does not work very well. If I apply the
sensitive property to the checkbutton, only the label is greyeyd out, not
the little box.
I find, this looks a little bit strange.
Is there a way to grey out the box of the checkbutton too ?

Thank You.
