[Tutor] Canvas Widget

[Diego Prestes]

Hi there,

     Im trying to use canvas in tkinter but when I put the widget it
always stay in the top of the program. I try to make a frame with the
side=TOP to put the buttons of the toolbar but it stay in bottom.

     Someone know if I can change the side of the canvas?

and other question. Someone know how can I create a rectangle, for
example, using the mouse?
