node editor - pyflow

[looo]

3. make Pyflow python3 compatible: PyFlow uses Qt.py and Qt.py is compatible to python 2 and 3 https://pypi.org/project/Qt.py/

PyFlow partially works with py3. The difficulties are introduced by your additions. Py3 is a critical point for me. Otherwise I can't contribute. But I guess your approach is to see the possibilities of the library.

Anyway: https://github.com/IlgarLunin/PyFlow/issues/45

[tak]

@microelly2 any chance you are moving over to python3? There are a lot of stuff not yet compatible with python3 in your modified library... I guess a node-editor not compatible with python3 has not much future.

There are not to many free node-editors available which can be embedded into FreeCAD.
I used some years ago pse (Python simulation editor) but pse is meantime ported from Qt to kivy, and there is no way to bring kivy and FreeCAD together.

PyFlow is already very complex - 30.000 lines of code.
It takes some time to read te source to understand how it works in detail and where FreeCAD can connect.
So my priorities are:

1. Is it possible to implement a use case where the node-editor simplifies the CAD workflow
2. Is it possible to add specific node types for FreeCAD concepts as separate python libraries
3. make Pyflow python3 compatible: PyFlow uses Qt.py and Qt.py is compatible to python 2 and 3 https://pypi.org/project/Qt.py/

It is wonderful. Thank you.
Beside, may I know why the UI in the youtube video(white one) is different with the source(black one)?

I made a node for the FreeCAD.Vector and for the FreeCAD.Console
The scripts now should run in python2 and python3 too.

Now I know the way to implement more complex data structures like Rotation, Placement, Colors into nodes and to organize the data exchange between the nodes.

Beside, may I know why the UI in the youtube video(white one) is different with the source(black one)?

I want to use the default layout of FreeCAD for the dialogs.

work in progress
I started a new workbench nodeditor, here the first methods

limitations for the moment:
still only tested on linux
both componentes run in different windows (FreeCAD PySide, PyFlow in PyQt)
no documentation

I'm so happy. Pyflow is a good friend to solve my tasks.Here my Enumeration pin demo.

very impresive. keep working!!

This would be awesome for the FreeCAD.trails WB and GeoMatics WB
