XmVaCreateSimplePulldownMenu(libraXrmyVacCarlela)teSimplePulldownMenu(library call)
NAME [Toc] [Back]
XmVaCreateSimplePulldownMenu - A RowColumn widget convenience creation
function
SYNOPSIS [Toc] [Back]
#include <Xm/RowColumn.h>
Widget XmVaCreateSimplePulldownMenu(
Widget parent,
String name,
int post_from_button,
XtCallbackProc callback);
DESCRIPTION [Toc] [Back]
XmVaCreateSimplePulldownMenu creates an instance of a RowColumn widget
of type XmMENU_PULLDOWN and returns the associated widget ID. This
routine uses the ANSI C variable-length argument list (varargs)
calling convention.
This routine creates a Pulldown menu pane and its button children.
The name of each button is button_n, where n is an integer from 0 to
the number of buttons in the menu minus 1. The name of each separator
is separator_n, where n is an integer from 0 to the number of
separators in the menu minus 1. The name of each title is label_n,
where n is an integer from 0 (zero) to the number of titles in the
menu minus 1. Buttons, separators, and titles are named and created
in the order in which they are specified in the variable portion of
the argument list.
This routine also attaches the PulldownMenu to a CascadeButton or
CascadeButtonGadget in the parent. The PulldownMenu is then posted
from this button.
parent Specifies the widget ID of the parent of the MenuShell.
name Specifies the name of the created widget.
post_from_button
Specifies the CascadeButton or CascadeButtonGadget in the
parent to which the Pulldown menu pane is attached. The
value is the integer n that corresponds to the nth
CascadeButton or CascadeButtonGadget specified for the
parent of the Pulldown menu pane. A Pulldown menu pane can
be attached only to a CascadeButton or CascadeButtonGadget,
and only CascadeButtons and CascadeButtonGadgets are counted
in determining the integer n. The first CascadeButton or
CascadeButtonGadget is number 0 (zero).
callback Specifies a callback procedure to be called when a button is
activated or when its value changes. This callback function
is added to each button after creation. For a
CascadeButtonGadget or a PushButtonGadget, the callback is

added as the button's XmNactivateCallback, and it is called
when the button is activated. For a ToggleButtonGadget, the
callback is added as the button's XmNvalueChangedCallback,
and it is called when the button's value changes. The
button number is returned in the client_data field.
The variable portion of the argument list consists of groups of
arguments. The first argument in each group is a constant or a string
and determines which arguments follow in that group. The last
argument in the list must be NULL. Following are the possible first
arguments in each group of varargs:
