XmVaCreateSimplePulldownMenu(3X) UNIX System V XmVaCreateSimplePulldownMenu(3X)
NAME
XmVaCreateSimplePulldownMenu - a RowColumn widget convenience creation
function.
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmVaCreateSimplePulldownMenu (parent, name, post_from_button,
callback, arg...)
Widget parent;
String name;
int post_from_button;
XtCallbackProccallback;
DESCRIPTION
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 MenuPane and its button children. The
name of each button is button_n, where n is an integer from 0 to one
minus the number of buttons in the menu. The name of each separator is
separator_n, where n is an integer from 0 to one minus the number of
separators in the menu. The name of each title is label_n, where n is an
integer from 0 to one minus the number of titles in the menu. 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 MenuPane is attached. The value is the
integer n that corresponds to the nth CascadeButton or
CascadeButtonGadget specified for the parent of the Pulldown
MenuPane. A Pulldown MenuPane 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.

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:
XmVaCASCADEBUTTON
This is followed by two additional arguments. The set specifies
one button in the PulldownMenu and some of its resource values.
The button created is a CascadeButtonGadget. Following are the
additional two arguments, in this order:
label The label string, of type XmString.
mnemonic
The mnemonic, of type KeySym.
XmVaPUSHBUTTON
This is followed by four additional arguments. The set specifies
one button in the PulldownMenu and some of its resource values.
The button created is a PushButtonGadget. Following are the
additional four arguments, in this order:
label The label string, of type XmString.
mnemonic
The mnemonic, of type KeySym.
accelerator
The accelerator, of type String.
accelerator_text
The accelerator text, of type XmString.
XmVaRADIOBUTTON
This is followed by four additional arguments. The set specifies
one button in the PulldownMenu and some of its resource values.
The button created is a ToggleButtonGadget. Following are the
additional four arguments, in this order:

accelerator
The accelerator, of type String.
accelerator_text
The accelerator text, of type XmString.
XmVaCHECKBUTTON
This is followed by four additional arguments. The set specifies
one button in the PulldownMenu and some of its resource values.
The button created is a ToggleButtonGadget. Following are the
additional four arguments, in this order:
label The label string, of type XmString.
mnemonic
The mnemonic, of type KeySym.
accelerator
The accelerator, of type String.
accelerator_text
The accelerator text, of type XmString.
XmVaTITLE
This is followed by one additional argument. The pair specifies a
title LabelGadget in the PulldownMenu. Following is the
additional argument:
title The title string, of type XmString.
XmVaSEPARATOR
This is followed by no additional arguments. It specifies one
separator in the PulldownMenu.
XmVaDOUBLE_SEPARATOR
This is followed by no additional arguments. It specifies one
separator in the PulldownMenu. The separator type is

XtVaTypedArg
This is followed by four additional arguments. The set specifies
a resource and its value for the RowColumn widget. A resource
type conversion is performed if necessary. Following are the
additional four arguments, in this order:
name The resource name, of type String.
type The type of the resource value supplied, of type String.
value The resource value (or a pointer to the resource value,
depending on the type and size of the value), of type
XtArgVal.
size The size of the resource value in bytes, of type int.
XtVaNestedList
This is followed by one additional argument of type XtVarArgsList.
This argument is a nested list of varargs returned by
XtVaCreateArgsList.

Intrinsics documentation.
A number of resources exist specifically for use with this and other
simple menu creation routines. For a complete definition of RowColumn
and its associated resources, see XmRowColumn(3X).
