GitLab

(popup_get_selection, popup_activated, popup_activate_callback,
menubar_selection_callback, popup_deactivate_callback,
single_submenu): New or replaced functions.

(popup_activated_flag): New variable.

(dispatch_dummy_expose, event_is_in_menu_item, map_event_to_object):
Removed.

(update_frame_menubar): Use lw_refigure_widget to provide widget set
independence.

(set_frame_menubar): Use lw_allow_resizing to control unsightly Motif
menubar resizing in a widget set independent fashion.

(xmenu_show): Removed menubar handling code, since that is now done in
lwlib.  Display a popup menu title centered and followed by two
separators.  Use lw_popup_menu() to display the menu.  Use
popup_get_selection() to deal with X11 event handling while the menu
is posted.
