register custom widget QTVCP

May I ask if someone created a custom widget how do i add it in QT Designer.

I already tryed
We must register our custom widget for Designer to use them.
Here is a typical samples
they would need to be added to qtvcp/plugins/
Then qtvcp/plugins/qtvcp_plugin.py would need to be adjusted
to import them.
but somehow i just get No module named ..._plugin

And the best way it to contribute back to linuxcnc.

ok first part i resolved
now the second question
the best way it to contribute back to linuxcnc??

You could post the code here if you like - i'll look at it.
Usually one creates a git clone of linuxcnc, modifies it then sets a 'pull request' on linuxcnc's github.
