I found that the problem applies to Button, but not Label. Using
root = tk.Tk() tk.Label(root, text="A", bg='green').pack(side=tk.LEFT, expand=tk.YES, fill=tk.Y) # align to the left-edge, tk.Label(root, text="B", bg='red').pack(side=tk.TOP, expand=tk.YES, fill=tk.BOTH) tk.Label(root, text="C", bg='blue').pack(side=tk.RIGHT, expand=tk.YES, fill=tk.NONE, anchor=tk.NE) tk.Label(root, text="D", bg='yellow').pack(side=tk.LEFT, expand=tk.NO, fill=tk.Y) tk.Label(root, text="E", bg='purple').pack(side=tk.TOP, expand=tk.NO, fill=tk.BOTH) tk.Label(root, text="F", bg='pink').pack(side=tk.TOP, expand=tk.NO, fill=tk.NONE) tk.Label(root, text="G", bg='green').pack(side=tk.BOTTOM, expand=tk.YES, fill=tk.Y) tk.Label(root, text="H", bg='red').pack(side=tk.TOP, expand=tk.NO, fill=tk.BOTH) tk.Label(root, text="I", bg='blue').pack(side=tk.RIGHT, expand=tk.NO) tk.Label(root, text="J", bg='yellow').pack(anchor=tk.SE) root.mainloop() I managed to get label.png as attached. Note that I forgot to add the button "F" in my previous example, but that's a trivial mistake that does not affect my point. Does it mean that currently Buttons cannot fill vertically no matter what?
