Hello, this problem has been solved. So, thank you Kyle.
Now I have a subsequent question: Do I have to use ADD_3D_WIDGET when I instatiate my custom widget within an own pqMyObjectPanel class? When I use this CMakeMacro I had some problems with my custom widget, because the constructor of my widget is beeing invoked two times, but I create only one instance within the pqMyObjectPanel class. Can someone give me a hint? Thanks again.
