qdragon.var file from PYTHON

Some way to use the parameters of the qdragon.var file from Python code in the same way that they can be declared from MDI (example: #4000 = 60)

I think you could probably just read the file into a string and parse it.
(I would probably use regex)

I'm not exactly sure how you want to use the varfile data.

You can, qtvcp widget origin_offsetview does this.
You must be careful when you read/write to it as linuxcnc does not monitor it for external changes and only syncs the file at specific times.
