John are you saying that if you click this link:
linuxcnc.org/docs/
you don't see this:



I've been using that link for years.

Hmm I thought linuxcnc.org/docs went to the current docs... I'll have to look into where that is... we seem to have some duplication again with the docs...

It may be handy but it's not maintained any more or part of the WLO so I have no clue where that is even though it's the base url for all the docs... it is not part of the buildbot which is buildbot.linuxcnc.org/doc

So anyway, to get back on topic, it turns out they can co-exist. You have to make sure the system environment variable EMC2_HOME is set to your home config directory. In my case after doing export EMC2_HOME=/home/jim/linuxcnc/configs/qtdragon I was then able to start qtdesigner with designer -qt=5. There's more stuff to sort out but it's a start.

Ya sorry about the topic abuse.

Well excellent. i was pretty sure they could coexist on designer, in fact they should be able to be placed on the same form and show up and work. What probably won't work is interactions between widgets of the two libraries unless that interaction uses linuxcnc NML commands or qt's signal/slots.
But I wouldn't advise building a screen using both libraries.
If you do dabble with qtvcp, I'll do my best to answer questions or fix bugs/add capabilities. Qtvcp does have quite a bit of docs - but they were written by me and I know how the widgets were meant to work.
