Owner receives only Delphi objects

[shineworld 73]

I need some help from Python + DelphiVCL guru.

Some time ago I've made a new DelphiVCL control to use VTK with Python + VCL + VTK.
To do that I've modified the Embarcadero's DelphiVCL package to add new control, called new library as cnc_vision_vcl

to not override already installad DelphiVCL library and all worked fine.

 

But I don't want to have a custom DelphiVCL and so I've tried to move the component in a delphivcl_ext project and

at now same code does not work.

What I've to in native Delphivcl code (which works)

1. Create a clone of DelphiVCL projects as cnc_vision_vcl.
2. Created new component WrapExtVTK.pas (attached).
3. Modified source\vcl\WrapVclControls to import new unit:

   uses
     WrapDelphiTypes,
     WrapDelphiClasses,
     WrapDelphiWindows,
     WrapDelphiDataBind,
     WrapActions,
     WrapVclImgList,
     WrapVclControls,
     WrapVclGraphics,
     WrapVclForms,
     WrapVclActnList,
     WrapVclMenus,
     WrapVclStdCtrls,
     WrapVclComCtrls,
     WrapVclExtCtrls,
     WrapVclButtons,
     WrapVclGrids,
     WrapVclSamplesSpin,
     WrapVclWinXCtrls,
     WrapVclThemes,
     WrapVclDialogs,
     WrapVclMedia,
     WrapExtVTK;    // <--- new unit

    

4. Compiled and used new cnc_vision_vcl.pyd file

5. In the cnc_vision_vcl a zip with working test
   
    

All work fine but I want to move component in an "ext"tra package to leave untouched original delphivcl,
so I've created a clean project which add almost the same code but when I try to create the VTKPanel
object I obtains: 

self.vtk_panel = VTKPanel(self)
                     ^^^^^^^^^^^^^^
AttributeError: Owner receives only Delphi objects

In next chat the zip of entire project because I've reached post limits.

I don't this is going to work.  You are going to have duplicates of what is supposed  to be Singletons (WrapDelphi, PythonEngine).  It may work with run-time packages, but you would have to put all run-time packages in the same folder as the pyd files.
