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;
XtCallbackProc callback;
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. But-
tons, 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. Specifies the widget ID of the parent of the MenuShell. Specifies the name of the created widget. Specifies the CascadeBut-
ton 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 Cas-
cadeButton or CascadeButtonGadget, and only CascadeButtons and CascadeButtonGadgets are counted in determining the integer n. The first
CascadeButton or CascadeButtonGadget is number 0. 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: 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: The label
string, of type XmString. The mnemonic, of type KeySym. 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: The label string, of type XmString. The mnemonic, of type KeySym. The accelerator, of type String. The accelerator text,
of type XmString. 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: The label
string, of type XmString. The mnemonic, of type KeySym. The accelerator, of type String. The accelerator text, of type XmString. 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: The label string, of type XmString. The
mnemonic, of type KeySym. The accelerator, of type String. The accelerator text, of type XmString. This is followed by one additional
argument. The pair specifies a title LabelGadget in the PulldownMenu. Following is the additional argument: The title string, of type
XmString. This is followed by no additional arguments. It specifies one separator in the PulldownMenu. This is followed by no additional
arguments. It specifies one separator in the PulldownMenu. The separator type is XmDOUBLE_LINE. This is followed by one additional argu-
ment, the value of the resource, of type XtArgVal. The pair specifies a resource and its value for the RowColumn widget. This is followed
by four additional arguments. The set specifies a resource and its value for the RowColumn widget. A resource type conversion is per-
formed if necessary. Following are the additional four arguments, in this order: The resource name, of type String. The type of the
resource value supplied, of type String. The resource value (or a pointer to the resource value, depending on the type and size of the
value), of type XtArgVal. The size of the resource value in bytes, of type int. This is followed by one additional argument of type
XtVarArgsList. This argument is a nested list of varargs returned by XtVaCreateArgsList.

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).
RETURN VALUE
Returns the RowColumn widget ID.
