Hi Grotius,
impressive work
Some words about dro style of gmoccapy:
*imho* its a big wastage of space. You don't need relative and absolute coordinates at the same time. Showing G54 does not make sense, as linux backend does not update that value in time.
And a symbol for hitting limit switch? - That situation is a vital error, which should stop the machine imediatelly.
The old machines I use at work have to be turned off to clear limit switch errors. So for that error you could use a fullscreen error message. Its not needed to waste space of graphical widget.

Hi Grotius,
a quick shot at QOpenGLWidget - no problem creating transparent overlay widgets.
So if QOpenGLWidget is usable as base for graphic output, then dro and graphic widgets could be separated and i.e. make it configurable, if dro should be painted at overlay location or outside of graphic widget.
Changed code looks like:
and changed constructor:
Cheers Reinhard

Hi Reinhard,
Thanks for your suggestion.
No luck with the QopenGlwidget and Opencascade combination.
The result is still the same, no tranceparancy. The QGlwidget is working better.

Hi,
Before finishing the c++ widget i thought maybe test the widget first if it's compatible with Python3.
You know, i'm no Python guru. But it would'nt be my style to leave it that way.
I don't know how Chris would make the interface with python, but i had to investegate this, and picked up a try :
I came accros this python example that creates a Python lib from a C++ lib : github.com/eyllanesc/Qt5toPyQt5/tree/master/src
Offcourse it did'nt work right away. I had to download and compile from source : sip-4.19.25 and PyQt5-15.4
Then it didn't work.
I had to include extra lib path's in the configure.py file of the github.com/eyllanesc/Qt5toPyQt5/tree/master/src example.
Attached the edited configure.py file for info.
Then i got the python modules and created a test script : test.py
Please don't look at my fragile python code style.
The python gui loaded and displaying the opencascade widget.
Trough the property system i could set the opencascade background picture.
So the QProperty system is also working oke for Python.

And one extra thing i can say : It's quite responsive.
Oke with this knowledge and if Chris can give his approval for the integration style, i can go on with this.
