Widget XmCreatePulldownMenu (parent, name, arglist, argcount) Widget parent; String name; ArgList arglist; Cardinal argcount;
XmCreatePulldownMenu is provided as a convenience function for creating RowColumn widgets configured to operate as Pulldown MenuPanes and is not implemented as a separate widget class.
A Pulldown MenuPane displays a 3-D shadow, unless the feature is disabled by the application. The shadow appears around the edge of the MenuPane.
A Pulldown MenuPane is used when creating submenus that are to be attached to a CascadeButton or a CascadeButtonGadget. This is the case for all MenuPanes that are part of a PulldownMenu system (a MenuBar), the MenuPane associated with an OptionMenu, and any MenuPanes that cascade from a Popup MenuPane. Pulldown MenuPanes that are to be associated with an OptionMenu must be created before the OptionMenu is created.
The Pulldown MenuPane must be attached to a CascadeButton or CascadeButtonGadget that resides in a MenuBar, a Popup MenuPane, a Pulldown MenuPane, or an OptionMenu. This is done by using the button resource XmNsubMenuId.
A MenuShell widget is required between the Pulldown MenuPane and its parent. If the application uses this convenience function for creating a Pulldown MenuPane, the MenuShell is automatically created as the real parent of the MenuPane; otherwise, it is the application's responsibility to create the MenuShell widget.
To function correctly when incorporated into a menu, the Pulldown MenuPane's hierarchy must be considered; this hierarchy depends on the type of menu system that is being built as follows:
PullDown MenuPanes support tear-off capabilities for tear-off menus through XmRowColumn resources. For a complete definition of RowColumn and its associated resources, see XmRowColumn(Xm).
