  38 // For each of *bars, a frame may have several of them, but only one is
  39 // managed by the frame, i.e. resized/moved when the frame is and whose size
  40 // is accounted for in client size calculations - all others should be taken
  41 // care of manually. The CreateXXXBar() functions create this, main, XXXBar,
  42 // but the actual creation is done in OnCreateXXXBar() functions which may be
  43 // overridden to create custom objects instead of standard ones when
  44 // CreateXXXBar() is called.
