 * 1) <no current parameter> displaying "Do XX" (empty text)
 * 2) <parameter present> displaying "Do XX with %1".
 * Provides a slot to set the parameter, changing display
 * and enabled state accordingly.
 * The text passed in should already be translated; parameterText
 * should contain a %1 where the parameter is to be inserted. */
