Architecture

The idea is to decorelate the Graphical part of the processing part. So the project is containing the core package which should be able to process all the action without any call to qt.GUI infine.

None graphical workflow

we can launch orange workflows from command line by using the interpreter

But you should follow the structure :

orangecontrib.esrf.core.xxx orangecontrib.esrf.widgets.xxxWidgets

orangecontrib.esrf.core should be Qt free.
