XtVaCreateArgsList(3) XT FUNCTIONS XtVaCreateArgsList(3)NAME
XtVaCreateArgsList - dynamically allocate a varargs list
SYNTAX
XtVarArgsList XtVaCreateArgsList(XtPointer unused, ...);
ARGUMENTS
unused Must be specified as NULL.
... Specifies a variable parameter list of resource name and value pairs.
DESCRIPTION
The XtVaCreateArgsList function allocates memory and copies its arguments into a single list pointer, which may be used with XtVaNest-
edList. The end of both lists is identified by a name entry containing NULL. Any entries of type XtVaTypedArg are copied as specified
without applying conversions. Data passed by reference (including Strings) are not copied, only the pointers themselves; the caller must
ensure that the data remain valid for the lifetime of the created varargs list. The list should be freed using XtFree when no longer
needed.

XmVaCreateSimpleCheckBox - A RowColumn widget convenience creation function
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmVaCreateSimpleCheckBox (parent, name, callback, arg...)
Widget parent;
String name;
XtCallbackProc callback;
DESCRIPTION
XmVaCreateSimpleCheckBox creates an instance of a RowColumn widget of type XmWORK_AREA and returns the associated widget ID. This routine
uses the ANSI C variable-length argument list (varargs) calling convention.
This routine creates a CheckBox and its ToggleButtonGadget children. A CheckBox is similar to a RadioBox, except that more than one button
can be selected at a time. 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. Buttons are named and created in the order in which they are specified in the variable portion of the argument list. Specifies the
parent widget ID. Specifies the name of the created widget. Specifies a callback procedure to be called when a button's value changes.
This callback function is added to each button after creation as the button's XmNvalueChangedCallback. The callback function is called
when a button's value changes, and 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 four additional arguments. The set specifies one button in the CheckBox and some of its
resource values. Following are the additional four arguments, in this order: The label string, of type XmString. The mnemonic, of type
KeySym. This is ignored in this release. The accelerator, of type String. This is ignored in this release. The accelerator text, of
type XmString. This is ignored in this release. 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. 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: 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.
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.
