I changed the 'Type evtype = Type.GetType ("Qt."+eventclass+",Qt");' to 'Type 
evtype = Type.GetType ("Qt."+eventclass);' and now I get this:

address@hidden:~/dev/qtsharp/src/examples/samples$ ilrun hello.exe
Uncaught exception: System.ArgumentException: Invalid attributes for 
Type.InvokeMember
        at System.Reflection.ClrType.InvokeMember(String, BindingFlags, 
Binder, Object, Object[], ParameterModifier[], CultureInfo, String[])
        at System.Activator.CreateInstance(Type, BindingFlags, Binder, 
Object[], CultureInfo, Object[])
        at System.Activator.CreateInstance(Type, BindingFlags, Binder, 
Object[], CultureInfo)
        at Qt.QtSupport.DispatchEvent(IntPtr, String, IntPtr, String)
        at Qt.QWidget.qt_QWidget_show(IntPtr)
        at Qt.QWidget.Show()
        at QtSamples.HelloWorld.Main(String[])

Segmentation fault
