  // Description:
  // Set/Get if the packing options should be changed automatically when
  // the frame is collapsed/uncollapsed. This if OFF by default. 
  // WARNING: turning this option will modify the -expand attribute in the
  // packing options automatically. Packing is usually the responsibility of 
  // the user, and no widget instance would usually change its own packing
  // option automatically, since this could be considered pulling the rug out
  // from under the user's feet. However, in some very specific case (say,
  // when packing a vtkKWMultiColumnList), you would want the widget packed
  // inside the frame with label to expand automatically. This can not be
  // done without allowing the vtkKWFrameWithLabel instance to expand
  // automatically as well, which is not compatible with the "collapsed" more.
  // To work around this, the -expand flag of the vtkKWFrameWithLabel has
  // to be changed automatically back and forth each time the frame is
  // collapsed/uncollapsed. Turning this variable ON will take care of it.

  // Description:
  // Update the "enable" state of the object and its internal parts.
  // Depending on different Ivars (this->Enabled, the application's 
  // Limited Edition Mode, etc.), the "enable" state of the object is updated
  // and propagated to its internal parts/subwidgets. This will, for example,
  // enable/disable parts of the widget UI, enable/disable the visibility
  // of 3D widgets, etc.
