Specifies the number of attribute/value pairs in the argument list
(arglist). When this function is used to create the Pulldown menu
pane, a MenuShell widget is automatically created as the parent of the
menu pane. If the widget specified by the parent parameter is a Popup
or a Pulldown menu pane, the MenuShell widget is created as a child of
the parent MenuShell; otherwise, it is created as a child of the
specified parent widget.
XmCreatePulldownMenu is provided as a convenience function for creating
RowColumn widgets configured to operate as Pulldown menu panes and is
not implemented as a separate widget class.
A Pulldown menu pane displays a 3-D shadow, unless the feature is
disabled by the application. The shadow appears around the edge of the
A Pulldown menu pane is used with submenus that are to be attached to a
CascadeButton or a CascadeButtonGadget. This is the case for all menu
panes that are part of a PulldownMenu system (a MenuBar), the menu pane
associated with an OptionMenu, and any menu panes that cascade from a
Popup menu pane. Pulldown menu panes that are to be associated with an
OptionMenu must be created before the OptionMenu is created.
The Pulldown menu pane must be attached to a CascadeButton or
CascadeButtonGadget that resides in a MenuBar, a Popup menu pane, a
Pulldown menu pane, or an OptionMenu. It is attached with the button
A MenuShell widget is required between the Pulldown menu pane and its
parent. If the application uses this convenience function for creating
a Pulldown menu pane, the MenuShell is automatically created as the
real parent of the menu pane; otherwise, it is the application's
responsibility to create the MenuShell widget.
To function correctly when incorporated into a menu, the Pulldown menu
pane's hierarchy must be considered. This hierarchy depends on the type
of menu system that is being built, as follows:
· If the Pulldown menu pane is to be pulled down from a MenuBar,
its parent must be the MenuBar.
· If the Pulldown menu pane is to be pulled down from a Popup or
another Pulldown menu pane, its parent must be that Popup or
Pulldown menu pane.
· If the Pulldown menu pane is to be pulled down from an
OptionMenu, its parent must be the same as the OptionMenu parent.
PullDown menu panes support tear-off capabilities for tear-off menus
through XmRowColumn resources. For a complete definition of RowColumn
