[Question] Is it possible to receive pythonocc-core objects inside my own SWIG wrapper? #877

Open Dogrtt opened 4 years ago

Dogrtt commented 4 years ago

I write small C++ lib that use OpenCASCADE, and I wanna provide possibility to accept and return pythonocc-core objects inside my own SWIG wrapper. For now if I got some method in C++ class that return TopoDS_Shape *, in Python I receive <Swig Object of type 'TopoDS_Shape *' at 0x00000204F9E32060>, but I wanna work with pythonocc-core classes. Is it possible to achieve that? Should I somehow describe %typemap of returned pointer?

rainman110 commented 4 years ago

Yes, it's definitely possible. We do the same for our c++ library tigl and achieve full interoperability with pythonocc.

Look at our implementation here : https://github.com/DLR-SC/tigl/tree/master/bindings/python_internal

rainman110 commented 4 years ago

The take home message is, that you have to import the TopoDS.i file from pythonocc-core in your Swig interface file. This makes TopoDS_Shape objects known to the swig type system

@rainman110 Thank you for advise. I take a look into tigl bindings, but some things is not clear for me. I didn't find where you %include <TopoDS.i> and how are you find PythonOCC libs by find_package(PythonOCC)? Anyway, thank you, it looks like I should spend a little bit more time to get the point.

rainman110 commented 4 years ago

Strange, you are right. It was defeinitely required once. This was the first version where it is still included: https://github.com/DLR-SC/tigl/blob/8116ca324b87e1d35eaf60582eb51a78beb9912b/bindings/python_internal/geometry.i

Maybe use this as an example.

and how are you find PythonOCC libs by find_package(PythonOCC)?

I wrote a cmake find script: https://github.com/DLR-SC/tigl/blob/master/cmake/FindPythonOCC.cmake

@rainman110 Yeah, thank you, I'm figured out how it should be included, but now I got a lot of errors on FooParserPYTHON_wrap.cxx building step. Almost all of them is about syntax errors and undeclared identifiers.

Your just missing the includes. You have to include some OCCT header files via

%{
#include<Standard_ErrorHandler.hxx>
#include<Standard_Failure.hxx>
%}

You proably need some more than these.

@rainman110 Thank you. Actually I include and import TopoDS.i inside my *.i file to make it work.
