// .NAME vtkXRenderWindowInteractor - an X event driven interface for a RenderWindow
// .SECTION Description
// vtkXRenderWindowInteractor is a convenience object that provides event
// bindings to common graphics functions. For example, camera and actor
// functions such as zoom-in/zoom-out, azimuth, roll, and pan. IT is one of
// the window system specific subclasses of vtkRenderWindowInteractor. Please
// see vtkRenderWindowInteractor documentation for event bindings.
//
// .SECTION see also
// vtkRenderWindowInteractor vtkXRenderWindow
// I've been though this and deleted all I think should go, tried to create
// the basic structure and if you're lucky it might even work!
// but frankly I doubt it

// want to have mouse interaction.

// Description:
// Break the event loop on 'q','e' keypress. Want more ???

// The BreakLoopFlag is checked in the Start() method.

// Description:
// Enable/Disable interactions. By default interactors are enabled when
// initialized. Initialize() must be called prior to enabling/disabling
// interaction. These methods are used when a window/widget is being
// shared by multiple renderers and interactors. This allows a "modal"
// display where one interactor is active when its data is to be displayed
// and all other interactors associated with the widget are disabled
// when their data is not displayed.
virtual void Enable();
virtual void Disable();
// Description:
// This will start up the X event loop and never return. If you
// call this method it will loop processing X events until the
// application is exited.
virtual void Start();
// Description:
// Update the Size data member and set the associated RenderWindow's
// size.
virtual void UpdateSize(int,int);
// Description:
// Specify the Xt widget to use for interaction. This method is
// one of a couple steps that are required for setting up a
// vtkRenderWindowInteractor as a widget inside of another user
// interface. You do not need to use this method if the render window
// will be a stand-alone window. This is only used when you want the
// render window to be a subwindow within a larger user interface.
// In that case, you must tell the render window what X display id
// to use, and then ask the render window what depth, visual and
// colormap it wants. Then, you must create an Xt TopLevelShell with
// those settings. Then you can create the rest of your user interface
// as a child of the TopLevelShell you created. Eventually, you will
// create a drawing area or some other widget to serve as the rendering
// window. You must use the SetWidget method to tell this Interactor
// about that widget. It's X and it's not terribly easy, but it looks cool.
virtual void SetWidget(Widget);
Widget GetWidget() {return this->Top;};
// Description
// This method will store the top level shell widget for the interactor.
// This method and the method invocation sequence applies for:
// 1 vtkRenderWindow-Interactor pair in a nested widget hierarchy
// multiple vtkRenderWindow-Interactor pairs in the same top level shell
// It is not needed for
// 1 vtkRenderWindow-Interactor pair as the direct child of a top level shell
// multiple vtkRenderWindow-Interactor pairs, each in its own top level shell
//
// The method, along with EnterNotify event, changes the keyboard focus among
// the widgets/vtkRenderWindow(s) so the Interactor(s) can receive the proper
// keyboard events. The following calls need to be made:
// vtkRenderWindow's display ID need to be set to the top level shell's
// display ID.
// vtkXRenderWindowInteractor's Widget has to be set to the vtkRenderWindow's
// container widget
// vtkXRenderWindowInteractor's TopLevel has to be set to the top level
// shell widget
// note that the procedure for setting up render window in a widget needs to
// be followed. See vtkRenderWindowInteractor's SetWidget method.
//
// If multiple vtkRenderWindow-Interactor pairs in SEPARATE windows are desired,
// do not set the display ID (Interactor will create them as needed. Alternatively,
// create and set distinct DisplayID for each vtkRenderWindow. Using the same
// display ID without setting the parent widgets will cause the display to be
// reinitialized every time an interactor is initialized), do not set the
// widgets (so the render windows would be in their own windows), and do
// not set TopLevelShell (each has its own top level shell already)
virtual void SetTopLevelShell(Widget);
Widget GetTopLevelShell() {return this->TopLevelShell;};

// Re-defines virtual function to get mouse position by querying X-server.
