[vtkusers] VTK tutorial, step 5 (Cone5), OSX-Cocoa: fails to capture keyboard events

[Darren Weber]

I've tried this change to vtkCocoaRenderWindow.mm and it seems to be working
when I build Cone6 without the MACOSX_BUNDLE option for cmake.

#include <vtksys/ios/sstream>
#include <CoreServices/CoreServices.h>
.
.
.
//----------------------------------------------------------------------------
void vtkCocoaRenderWindow::MakeCurrent()
{
  if (this->GetContextId())
    {
    [(NSOpenGLContext*)this->GetContextId() makeCurrentContext];
    }


  // ****  BEGIN EDIT
  // Adding process control so the window gets keyboard events.
  ProcessSerialNumber psn = { 0, kCurrentProcess };
  TransformProcessType( &psn, kProcessTransformToForegroundApplication );
  // **** END EDIT


}



I wonder if the 'psn' variable should be put into an init method instead?
If so, I guess there should be a method to get it too.

Best, Darren
