Indicates when the icon has been activated following the single or doubleclick settings

Signal syntax:
  `QObject.connect(source, SIGNAL("activated()"), target_slot)`

changed | ( |  | ) |

Indicates that something about the icon may have changed (image, text, etc) only actually works for icons associated with an action

Signal syntax:
  `QObject.connect(source, SIGNAL("changed()"), target_slot)`
