# ::tk::TearoffMenu --
# Given the name of a menu, this procedure creates a torn-off menu
# that is identical to the given menu (including nested submenus).
# The new torn-off menu exists as a toplevel window managed by the
# window manager. The return value is the name of the new menu.
# The window is created at the point specified by x and y
#
# Arguments:
# w - The menu to be torn-off (duplicated).
# x - x coordinate where window is created
# y - y coordinate where window is created
proc ::tk::TearOffMenu {w {x 0} {y 0}} {
# Find a unique name to use for the torn-off menu. Find the first
# ancestor of w that is a toplevel but not a menu, and use this as
# the parent of the new menu. This guarantees that the torn off
# menu will be on the same screen as the original menu. By making
# it a child of the ancestor, rather than a child of the menu, it
# can continue to live even if the menu is deleted; it will go
# away when the toplevel goes away.
