Menus
Class Menu
implements all kinds of menus: menu bars of top-level windows, submenus, and pop-up menus. To use a Menu
instance m
as the menu bar for a top-level window w
, set w
’s configuration option menu=
m
. To use m
as a submenu of a Menu
instance x
, call x
.add_cascade
with menu=
m
. To use m
as a pop-up menu, call m
.post
.
Besides configuration options covered in Common Widget Options, a Menu
instance m
supports option postcommand=
callable
. Tkinter
calls callable
without arguments each time it is about to display m
(because of a call to m
.post
or because of user actions). Use this option to update a dynamic menu just in time when necessary.
By default, a Tkinter
menu shows a tear-off entry (a dashed line before other entries), which lets the user get a copy of the menu in a separate Toplevel
window. Since such tear-offs are not part of user interface standards on popular platforms, you may want to disable tear-off functionality by using configuration option tearoff=0
for the menu.
Menu-Specific Methods
Besides methods common to all widgets, an instance m
of class Menu
supplies several menu-specific methods.
