// .NAME vtkXRenderWindowTclInteractor - a TCL event driven interface for a RenderWindow
// .SECTION Description
// vtkXRenderWindowTclInteractor 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
#ifndef __vtkXRenderWindowTclInteractor_h
#define __vtkXRenderWindowTclInteractor_h
//===========================================================
// now we define the C++ class
#include "vtkRenderWindowInteractor.h"
#include <X11/StringDefs.h> // Needed for X types in public interface

{
public:

vtkTypeRevisionMacro(vtkXRenderWindowTclInteractor,vtkRenderWindowInteractor);
void PrintSelf(ostream& os, vtkIndent indent);
// Description:
// Initializes the event handlers without an XtAppContext. This is
// good for when you don't have a user interface, but you still
// want to have mouse interaction.
virtual void Initialize();
// Description:
// Initializes the event handlers using an XtAppContext that you have
// provided. This assumes that you want to own the event loop.
virtual void Initialize(XtAppContext app);
vtkGetMacro( App, XtAppContext );
// 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();
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:
// * vtkRenderWindow-Interactor pair in a nested widget hierarchy
// * multiple vtkRenderWindow-Interactor pairs in the same top
// level shell
//
// It is not needed for:
// * vtkRenderWindow-Interactor pair as the direct child of a
// top level shell,
// * multiple vtkRenderWindow-Interactor pairs, each in its own
// top level shell.
//
// This 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);
