XmVaCreateSimplePulldownMenu(libraryXmVaCreateSimplePulldownMenu(library call)NAMEXmVaCreateSimplePulldownMenu — A RowColumn widget convenience creation
function
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmVaCreateSimplePulldownMenu(
Widget parent,
String name,
int post_from_button,
XtCallbackProc callback);
DESCRIPTIONXmVaCreateSimplePulldownMenu 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 Cas‐
cadeButtonGadget 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 Cascade‐
Button 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 Cas‐
cadeButtons and CascadeButtonGadgets are counted in determin‐
ing the integer n. The first CascadeButton or CascadeButton‐
Gadget 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 CascadeButton‐
Gadget or a PushButtonGadget, the callback is added as the
button's XmNactivateCallback, and it is called when the but‐
ton 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 argu‐
ments. 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 speci‐
fies one button in the PulldownMenu and some of its resource
values. The button created is a CascadeButtonGadget. Follow‐
ing are the additional two arguments, in order:
label The label string, of type XmString
mnemonic The mnemonic, of type KeySym
XmVaPUSHBUTTON
This is followed by four additional arguments. The set speci‐
fies one button in the PulldownMenu and some of its resource
values. The button created is a PushButtonGadget. Following
are the additional four arguments, in 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 speci‐
fies one button in the PulldownMenu and some of its resource
values. The button created is a ToggleButtonGadget. Following
are the additional four arguments, in 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
XmVaCHECKBUTTON
This is followed by four additional arguments. The set speci‐
fies one button in the PulldownMenu and some of its resource
values. The button created is a ToggleButtonGadget. Following
are the additional four arguments, in 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 speci‐
fies 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 XmDOU‐
BLE_LINE.
resource_name
This is followed by one additional argument, the value of the
resource, of type XtArgVal. The pair specifies a resource and
its value for the RowColumn widget.
XtVaTypedArg
This is followed by four additional arguments. The set speci‐
fies a resource and its value for the RowColumn widget. A
resource type conversion is performed if necessary. Following
are the additional four arguments, in 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.
For more information on variable-length argument lists, see the X Tool‐
kit 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(3).
RETURN
Returns the RowColumn widget ID.
