[vtkusers] Problem QVTKWidget using vtkCarbonRenderWindow instead of vtkCocoaRenderWindow

[Elvis Dowson]

Hi,
         I just downloaded the latest vtk-5.x sources from cvs  
(vtk-5.3) and tried to compile shared libraries, with

Problem Outline

VTK_USE_CARBON=OFF
VTK_USE_COCOA=ON
VTK_GUI_SUPPORT=ON
VTK_USE_QVTK=ON
DESIRED_QT_VERSION=4

I am using qt-4.4.2 for mac os, which has support for Cocoa.

Somehow, even through I have disabled support for Carbon, this error  
comes up.

   "vtkCarbonRenderWindow::UpdateGLRegion()", referenced from:
       QVTKWidget::DirtyRegionProcessor(OpaqueEventHandlerCallRef*,  
OpaqueEventRef*, void*)   in libQVTK.a(QVTKWidget.o)

If I look at the file GUISupport/Qt/CMakeLists.cxx (what is this file  
used for BTW?)

I see the following implementation. Shouldn't it use  
vtkCocoaRenderWindow instead?

#if defined (Q_WS_MAC) && QT_VERSION >= 0x040000
OSStatus QVTKWidget::DirtyRegionProcessor(EventHandlerCallRef,  
EventRef event, void* wid)
{
   QVTKWidget* widget = reinterpret_cast<QVTKWidget*>(wid);
   UInt32 event_kind = GetEventKind(event);
   UInt32 event_class = GetEventClass(event);
   if(event_class == 'cute' && event_kind == 20)
     {
     static_cast<vtkCarbonRenderWindow*>(widget->GetRenderWindow())- 
 >UpdateGLRegion();
     }
   return eventNotHandledErr;
}

#endif


If I look at the file QVTKWidget.h

there is no implementation for the case when qt version >= 4 and the  
user selects the Cocoa libraries.

#if defined(Q_WS_MAC) && QT_VERSION >= 0x040000
#include <Carbon/Carbon.h>    // Event handling for dirty region
#endif

How can I go about trying to fix this?

Where is Q_WS_MAC defined?

General Question

What should I do to make the modifications to support Cocoa for QVTK?


Best regards,
