— A RowColumn widget convenience creation
creates an instance of a RowColumn widget of
and returns the associated widget ID. This routine
uses the ANSI C variable-length argument list ( varargs
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
an integer from 0 (zero) to the number of buttons in the menu minus 1. 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
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.
The following list describes the possible first arguments in each group of
- This is followed by four additional arguments. The set specifies one
button in the CheckBox and some of its resource values. The following list
describes the additional four arguments, in 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
- The accelerator text, of type XmString. This is ignored in this
- 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
- 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 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
