// .NAME vtkCocoaRenderWindowInteractor - implements Cocoa specific functions

|
// required by vtkRenderWindowInteractor.
|
|
//
|
|
// .SECTION Description
|
|
// The interactor interfaces with vtkCocoaRenderWindow and vtkCocoaGLView
|
|
// to trap messages from the Cocoa window manager and send them to vtk.
|
|
|
|
// IMPORTANT: 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. Pitty.
