Hi,
I’m wondering if I have compiled widget `qMyWidget` and binded it to python (standard case in Slicer). Is it possible to promote widget to `qMyWidget` for python module in QDesigner?

You can directly use a widget in Qt Designer if you created a designer plugin for it. Most widgets in Slicer have a designer plugin, so you can use those as examples.
If you don’t have a plugin then maybe promotion works, but I don’t know if it is done anywhere. If we need to add a custom widget somewhere then we usually add a frame in Qt designer and then instantiate and add the custom widget in the widget’s setup method.

That was my case
As I remember I used to have custom widget written in C++ and tried to `promote` to it and use the generated `.ui` file with python… I didn’t succeded.
Probably later I will try it again
