shineworld 73 Posted July 1 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) Create a clone of DelphiVCL projects as cnc_vision_vcl. Created new component WrapExtVTK.pas (attached). 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 Compiled and used new cnc_vision_vcl.pyd file 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. WrapExtVTK.pas cnc_vision_vcl.zip Share this post Link to post

pyscripter 612 Posted July 1 (edited) 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. Edited July 1 by pyscripter Share this post Link to post
