Qtvcp use with grinder

for the malfunction original control we prepared a pin-compatible linuxcnc based on motenc and touchy with one tab for teach-in and use with macros in MDI

hope to use Qtvcp for grinder specific control

just installed 2.8.0-pre1-4824-g9b55a730b and then for Qtvcp 2.2. Get Designer to include linuxcnc widgets some troubles to complete

in the actual manual:
..........
then you must add a link to the qtvcp_plugin.py to the folder that designer will search.

In a RIP version of linuxcnc qtvcp_plugin.py will be in:
~/LINUXCNC_PROJECT_NAME/lib/python/qtvcp/plugins/qtvcp_plugin.py

installed version should be:
usr/lib/python2.7/qtvcp/plugins/qtvcp_plugin.py

Designer searches in these two place for links (pick one):
This can be:
/usr/lib/x86_64-linux-gnu/qt5/plugins/designer/python
or
~/.designer/plugins/python
...........

how should this link be added explicit?
my installation shows
/usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py
instead of
usr/lib/python2.7/qtvcp/plugins/qtvcp_plugin.py

it is best to use the
~/.designer/plugins/python
Folder as you can easy access and make changes

~/.designer/plugins/python does not exist in my actual installation, but I found

~/.designer/backup/ folder
~/.designer/templates/ folder
~/.designer/gradients.xml file
~/.designer/PyQt5 empty file renamed to PyQt5_orig
~/.designer/qtvcp_plugin.py empty file renamed to qtvcp_plugin_orig.py

added this two links
ln -s /usr/lib/python2.7/dist-packages/PyQt5 ~/.designer/PyQt5
ln -s /usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py ~/.designer/qtvcp_plugin.py

but result in designer no linuxcnc widgets visible

and linuxcnc qtvcp shows Error

looks like you need to add the svg python module:
python-pyqt5-qtsvg

should be it

~/.designer/plugins/python the folder might be need to be made.

I always use the path (you need to be root):
/usr/lib/x86_64-linux-gnu/qt5/plugins/designer/python

if you right click this:
/usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py
There should be an option to make a link - then move this link to
/usr/lib/x86_64-linux-gnu/qt5/plugins/designer/python
you may need to add the python folder.

Another user has said he had trouble with an installed version of Qtvcp.
I have not had time to investigate - I always use RIP.

Seems like it didn't find the toolfile - i'll have to look into it. - it should not crash anyways - it should just ignore.
Isit the same with all the other sample screens?
Did you get the linuxcnc widgets to show in Designer?

sorry, there is some Swiss German visible ;)
not all screen examples are loadable, there come some errors, I'll report later a little closer, calmed down and very satisfied what works already, now at first I would like to prepare and to clarify the imaginations for the grinder graphical interface.

Looks like you are still not getting the linuxcnc widgets.
I have to find (or install) a version of debian to install linuxcnc on to to test.
