 * Setters are defined that allow the user to change the
 * visual component associated with any control. A version
 * of these setters allows for the definition of a new
 * listener.
 *
 * Two constructors are defined. The first builds all
 * the default controls into the control panel. The
 * second takes a flag which defines the controls to be
 * built and displayed by the control panel.
 * The flag values are defined by public static values
 * provided by the class. These values can be OR'd together
 * to set a flag value.
