[PySide] Generating Shiboken bindings for simple QGraphicsView subclass Seg-Faults on import

[Daniel Smith]

Hey All,






   class TestView : public QGraphicsView {

        public :

            // Constructors
            TestView(QWidget *parent=NULL);
   };

   TestView::TestView(QWidget *parent) : QGraphicsView(parent) {

   }



   <?xml version="1.0"?>
   <typesystem package="test">
   <load-typesystem name="typesystem_core.xml" generate="no"/>
   <load-typesystem name="typesystem_gui.xml" generate="no"/>
   <object-type name="TestView"/>
   </typesystem>

and a global.h :

   #undef QT_NO_STL
   #undef QT_NO_STL_WCHAR

   #ifndef NULL
   #define NULL    0
   #endif

   #include "pyside_global.h">
   #include <test.hh>



Here's the gdb back trace :

Any help would be greatly appreciated!

Has anyone hit any roadblocks generating bindings (using Shiboken) for QGraphicsView subclasses? I'm not having any luck. I've been able to work my code down to a super simple test case (attached) which consists of a simple library, libtest, which is essentially just a single QGraphicsView subclass : I then have a standard Shiboken setup with a typesystem.xml containing a single object-type entry for TestView : If I then 'make' the project, everything compiles fine, but the resulting module seqmentation faults on import inside Shiboken::ObjectType::getMultipleIheritanceFunction(SbkObjectType*).
