#
# Bindings for Menubuttons.
#
# Menubuttons have three interaction modes:
#
# Pulldown: Press menubutton, drag over menu, release to activate menu entry
# Popdown: Click menubutton to post menu
# Keyboard: <Key-space> or accelerator key to post menu
#
# (In addition, when menu system is active, "dropdown" -- menu posts
# on mouse-over.  Ttk menubuttons don't implement this).
#
# For keyboard and popdown mode, we hand off to tk_popup and let 
# the built-in Tk bindings handle the rest of the interaction.
#
# ON X11:
#
# Standard Tk menubuttons use a global grab on the menubutton.
# This won't work for Ttk menubuttons in pulldown mode,
# since we need to process the final <ButtonRelease> event,
# and this might be delivered to the menu.  So instead we
# rely on the passive grab that occurs on <ButtonPress> events,
# and transition to popdown mode when the mouse is released
# or dragged outside the menubutton.
# 
# ON WINDOWS:
#
# I'm not sure what the hell is going on here.  [$menu post] apparently 
# sets up some kind of internal grab for native menus.
# On this platform, just use [tk_popup] for all menu actions.
# 
# ON MACOS:
#
# Same probably applies here.
