[Tkinter] How to create scrollable frame

[deanhystad]

You don't call super().__init__() or tk.Frame.__init__(self) in your ScrollableFrame.__init__() method. I noticed this when I tried to bind a function to the <configure> event. The frame doesn't have a window, so the request failed. There's probably many oddities occurring because your Scrollable frame is only partially a frame.

What is the purpose of the master_frame? You need a frame in which to place the canvas and scrollbars, but this should be the ScrollableFrame (self). Get rid of the master_frame and make the ScrollableFrame the parent of the canvas. This will clean up a lot of ugly in your code.

        self.pack = self.master_frame.pack  # Yuck!
        self.grid = self.master_frame.grid
        self.place = self.master_frame.place
        self.pack_forget = self.master_frame.pack_forget
        self.grid_forget = self.master_frame.grid_forget
        self.place_forget = self.master_frame.place_forget

Why is your ScrollableFrame height so large? The ScrollableFrame height should be the height of what is currently the master_frame.

You should not have to specify hscroll or vscroll. If the scrolling window is wider than the viewport you should display a horizontal scrollbar. If the scrolling window is taller than the viewport you should display a vertical scrollbar. If your scrolling window is smaller than the viewport there should be no scrollbars and you might want to expand the scrolling window to fill the viewport.
