[Tkinter-discuss] Working with tear-off menus (change the "-----" label, customize location/appearance of tear-off window)

[python at bdurham.com]

Hi Michael,

Thank you for your help. Your solution works well (tested under Windows
7 with 32-bit Python 2.7).

Regards,
Malcolm

Here on linux (I guess it should be the same on windows) the
tearoffcommand takes two arguments, first the menu itself and second the
newly created toplevel window, both as strings however, and Tkinter
doesn't know about the toplevel, so you will have to use the tcl-syntax
again :(

See this example:

from Tkinter import *
root = Tk()

def foo(menu, top):
    root.nametowidget(menu).add_command(label='baz')
    root.tk.call('wm', 'resizable', top,  '0', '0')

m = Menu(root, tearoffcommand=foo)
m.add_command(label='foo')
m.add_command(label='bar')
m.add_command(label='blah')

root.bind('<3>', lambda event: m.tk_popup(event.x_root, event.y_root))

root.mainloop()
