[vtkusers] Mac OS X x86_64 with Qt-4.5.x,vtk-5.3.x

[Chris Kees]

Hi,

Yesterday I compiled the cvs head of vtk with the development snapshot  
of Qt-4.5 following some of the recent posts on running in 64-bit with  
Cocoa.  If I set useMainWindow=False then the code below runs fine,  
otherwise I get an EXC_BAD_ACCESS signal when I call mainWindow.show()  
(output from gdb is below). Has anybody been able to add the vtk  
widget to a QFrame yet? I'm new to GUI programming, and I'm not sure I  
follow everything covered in the previous posts.  There is a comment  
in the QVTKRenderWindow documentation about need to call  
SetDisplayId() and SetWindowId() in certain situations, but I don't  
know how to call those. Thanks for any suggestions.

Chris

         if useMainWindow:
             #Qt widgets
             self.frameWidget = QtGui.QFrame(g.mainWindow)
             self.hbox = QtGui.QHBoxLayout()
             self.iren = QVTKRenderWindowInteractor(self.frameWidget)
              
self.iren.SetInteractorStyle(vtkInteractorStyleTrackballCamera())
             self.iren.Initialize()
             self.renWin = self.iren.GetRenderWindow()
             self.renWin.SetWindowName(name)
             self.hbox.addWidget(self.iren)
             self.frameWidget.setLayout(self.hbox)
             g.tabWidget.addTab(self.frameWidget,title)
             screen = QtGui.QDesktopWidget().screenGeometry()
             size = g.mainWindow.geometry()
             (x,y) = (screen.width()-comm.size()*size.width())/2,  
(screen.height()-size.height())/2
             g.mainWindow.move(x+comm.rank()*size.width(),y)
             g.mainWindow.show()
         else:
             self.iren = QVTKRenderWindowInteractor()
              
self.iren.SetInteractorStyle(vtkInteractorStyleTrackballCamera())
             self.iren.Initialize()
             self.renWin = self.iren.GetRenderWindow()
             self.renWin.SetWindowName(name)
