NAME

motif_pulldown_menu - a pull down menu

DESCRIPTION

A PulldownMenu is part of a menu system that normally consists of a MenuBar and a CascadeButton. A PulldownMenu is used to create submenus that are attached to a CascadeButton or CascadeButtonGadget. A PulldownMenu must be attached (using the subMenuId resource) to a CascadeButton or CascadeButtonGadget that resides in a MenuBar, a PopupMenu, a PulldownMenu, or an OptionMenu. If the PulldownMenu is to be pulled from a MenuBar, its parent must be the MenuBar. If it is to be pulled from a PopupMenu or another PulldownMenu, its parent must be that PopupMenu or PulldownMenu. it is to be pulled down from an OptionMenu, its parent must be the same as the OptionMenu parent.

PulldownMenu is a RowColumn widget and thus inherits the RowColumn resources.

INSTANCE VARIABLES

MESSAGES

@ resource selects resource for a subsequent set or query.

: value sets the current resource to value. Since most resources have mixed case, you should enclose any resource name in quotes. Resource names are the Motif names with the XmN prefix removed. Some resources can only be set before the widget is created. For efficiency, set as many resources as you can before creation.

scalar_value? returns the value of the current resource whose type is integer.

string_value? returns the value of the current resource whose type is string.

pointer_value? returns the value of the current resource whose type is a pointer of any kind.

create! creates an instance of the widget. Any resources that have been specified prior to the create! will be set. An id? message also sends a create!.

on! realizes the widget. Realizing a widget creates its windows and displays it when it is managed.
