On a basic program (launcher) I have a scrollbar problem : they make the background-picture move but not the forderground widgets (buttons).
The GUI is built as follow :
- Level 0 (parent = self) : Canvas (self.c) as background with a picture + scrollbars
- Level 1 (parent = self.c) : Buttons + an invisible Frame
Here is the code :

self.ascenseur_x.grid(row=1, column=0, sticky="ew")
# Canvas self.c - all other widgets but the scrollbars are in self.c

The scrollbars make the Canvas "self.c" move but not the buttons which are in the canvas. After a lot of tests I still don't find the mistake. Does someone have an idea about the problem?
Thanks!
