[unkcpz]

after aiidalab/aiidalab-widgets-base#375, these changes are needed here.

@unkcpz thanks to this PR I was able to adapt my app quite quickly, thanks!

I think you also need to fix the CalcJobNodeViewer in widgets.py, see the corresponding changes in my app, which reuses this code verbatim.

I wonder if the CalcJobNodeViewer and its dependencies shouldn't be merged to AWB as it is quite useful, and there seems to be some overlap with existing widgets in aiidalab_widgets_base/process.py

I am fully on it. I think the initial idea from @csadorf is we need to first have the widget implemented in App and after finding it useful and having APIs well-defined, move the widget to the aiidalab-widgets-base. The widgets shared by qeApp and your app match this condition. I'll decouple it from here.

Since this is anyway needed and tested in the Mig2.x. I close this PR and put all things to #271
