A RowColumn widget convenience creation function

DESCRIPTION

XmVaCreateSimpleRadioBox 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 RadioBox and its ToggleButtonGadget children. The name of each button is button_ n, where n is an integer from 0 (zero) to the number of buttons in the menu minus 1.

parent
Specifies the parent widget ID.

name
Specifies the name of the created widget.

button_set
Specifies which button is initially set. The value is the integer n in the button name button_ n.

callback
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:

XmVaRADIOBUTTON
This is followed by four additional arguments. The set specifies one button in the RadioBox and some of its resource values. Following are the additional four arguments, in order:

label
The label string, of type XmString.

mnemonic
The mnemonic, of type KeySym . This is ignored in this release.

accelerator
The accelerator, of type String. This is ignored in this release.

accelerator_text
The accelerator text, of type XmString. This is ignored in this release.

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 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 (3).

RETURN

Returns the RowColumn widget ID.
