// .NAME vtkCocoaTkUtilities - Internal Tk Routines for Cocoa
//
// .SECTION Description
// vtkCocoaTkUtilities provide access to the Tk internals for Cocoa
// implementations of Tk. These internals must be implemented in a .mm
// file, since Cocoa is Objective-C, but the header file itself is
// pure C++ so that it can be included by other VTK classes.
//
// .SECTION See Also
// vtkCocoaGLView
// .SECTION Warning
// This header must be in C++ only because it is included by .cxx files.
// That means no Objective-C may be used. That's why some instance variables
// are void* instead of what they really should be.
#ifndef __vtkvtkCocoaTkUtilities_h
#define __vtkvtkCocoaTkUtilities_h

// Description:
// Return the NSView for a Tk_Window. It is returned as a void pointer
// so that users of this function don't need to compile as Objective C.
