SDK X11 R4.11MU05 XmVaCreateSimplePulldownMenu(3X)
NAME
XmVaCreateSimplePulldownMenu--A RowColumn widget convenience creation
function
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmVaCreateSimplePulldownMenu (parent, name, postfrombutton,
callback, arg...)
Widget parent;
String name;
int postfrombutton;
XtCallbackProccallback;
DESCRIPTION
XmVaCreateSimplePulldownMenu creates an instance of a RowColumn
widget of type XmMENUPULLDOWN 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.
postfrombutton
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 clientdata 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.
acceleratortext
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:
label The label string, of type XmString.
mnemonic
The mnemonic, of type KeySym.
accelerator
The accelerator, of type String.
acceleratortext
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.
acceleratortext
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.
XmVaDOUBLESEPARATOR
This is followed by no additional arguments. It specifies
one separator in the PulldownMenu. The separator type is
XmDOUBLELINE.
resourcename
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
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.
For more information on variable-length argument lists, see the X
Toolkit 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).
RETURN VALUE
Returns the RowColumn widget ID.
