// .NAME vtkCocoaGLView - Cocoa OpenGL rendering context
//
// .SECTION Description
// This class is a subclass of Cocoa's NSView; it uses Objective-C++.
// This class overrides several NSView methods.
// To provide the usual VTK keyboard user interface, it overrides the
// following methods: acceptsFirstResponder, keyDown:,
// keyUp:, and flagsChanged:
// To provide the usual VTK mouse user interface, it overrides the
// following methods: mouseMoved:, mouseEntered:,
// mouseExited: scrollWheel:, mouseDown:, rightMouseDown:,
// otherMouseDown:, mouseDragged:, rightMouseDragged:, otherMouseDragged:,
// and updateTrackingAreas.
// To be able to render and draw onscreen, it overrides drawRect:.
// Compatibility notes:
// - this class was previously a subclass of NSOpenGLView,
// but starting with VTK 5.0 is now a subclass of NSView.
// - starting with VTK 6.3 this class overrides the more modern
// updateTrackingAreas instead of resetCursorRects.
//

#ifndef vtkCocoaGLView_h
#define vtkCocoaGLView_h
#import <Cocoa/Cocoa.h>
// Note: This file should be includable by both pure Objective-C and Objective-C++ source files.
// To achieve this, we use the neat technique below:
#ifdef __cplusplus
// Forward declarations
class vtkCocoaRenderWindow;
class vtkCocoaRenderWindowInteractor;
// Type declarations
typedef vtkCocoaRenderWindow *vtkCocoaRenderWindowRef;
typedef vtkCocoaRenderWindowInteractor *vtkCocoaRenderWindowInteractorRef;
#else
// Type declarations
typedef void *vtkCocoaRenderWindowRef;
typedef void *vtkCocoaRenderWindowInteractorRef;
#endif
@interface vtkCocoaGLView : NSView
{
@private
vtkCocoaRenderWindowRef _myVTKRenderWindow;
NSTrackingArea* _rolloverTrackingArea;
}
- (vtkCocoaRenderWindowRef)getVTKRenderWindow;
- (void)setVTKRenderWindow:(vtkCocoaRenderWindowRef)theVTKRenderWindow;
- (vtkCocoaRenderWindowInteractorRef)getInteractor;
