Here is a code fragment showing the creation of a canvas
with horizontal and vertical scrollbars. In this
fragment, self
is assumed to be a Frame
widget.
self.canv = tk.Canvas(self, width=600, height=400, scrollregion=(0, 0, 1200, 800)) self.canv.grid(row=0, column=0) self.scrollY = tk.Scrollbar(self, orient=tk.VERTICAL, command=self.canv.yview) self.scrollY.grid(row=0, column=1, sticky=tk.N+tk.S) self.scrollX = tk.Scrollbar(self, orient=tk.HORIZONTAL, command=self.canv.xview) self.scrollX.grid(row=1, column=0, sticky=tk.E+tk.W) self.canv['xscrollcommand'] = self.scrollX.set self.canv['yscrollcommand'] = self.scrollY.set
Notes:
The connection goes both ways. The canvas's xscrollcommand
option has to be connected to
the horizontal scrollbar's .set
method, and the scrollbar's command
option has to be connected to the canvas's .xview
method. The vertical scrollbar and
canvas must have the same mutual connection.
The sticky
options on the .grid()
method
calls for the scrollbars force them to stretch just
enough to fit the corresponding dimension of the
canvas.
