  // system supports this).
  // For convenience purposes, the MasterWindow does not have to be a

  // Specifies a non-negative value indicating how much extra space to request
  // for the widget in the X and Y-direction. When computing how large a
  // window it needs, the widget will add this amount to the width it would
  // normally need (as determined by the width of the things displayed
  // in the widget); if the geometry manager can satisfy this request, the

  // inside.

  // Description:
  // Set/Get the position this toplevel should be centered at when Display()

  // position at all and let the user or the window manager place the toplevel.
  // If set to MasterWindowCenter, the toplevel is centered inside its master 
  // window ; if  the MasterWindow ivar is not set, it is centered on the
  // screen, which is similar to the ScreenCenter setting. If set to 
  // Pointer, the toplevel is centered at the current mouse position.
  // On some sytem, the default setting can lead the window manager to
  // place the window at the upper left corner (0, 0) the first time it
  // is displayed. Since this can be fairly annoying, the 
  // MasterWindowCenterFirst and ScreenCenterFirst can be used to center
  // the toplevel relative to the master window or the screen only the
  // first time it is displayed (after that, the toplevel will be displayed
  // wherever it was left).

  // of this object.

  // typically invoked when the user closes the window using the
  // window manager.
  // The 'object' argument is the object that will have the method called on
  // it. The 'method' argument is the name of the method to be called and any

  // Kept for compatibility purposes, use vtkKWApplication instead.
  virtual vtkKWTclInteractor* GetTclInteractor();

  // 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.

  // Events. 
  // WithdrawEvent is called when the toplevel has been withdrawn, as a result
  // of calling the Withdraw() method. DisplayEvent is called when the 
  // toplevel has been displayed by calling the Display() method.
  // SlaveDisplayEvent is invoked when a slave toplevel of that instance is
  // displayed (i.e. a toplevel whose MasterWindow was set to this instance).
