[Tkinter-discuss] pack(fill=Y) not working as expected

[Beinan Li]

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?

Thanks,
Beinan
