Is there a way to insert a QWidget as an item in a QComboBox (instead of a string)?

Question

I'd like to have a QCalendarWidget as the only item in a QComboBox, but from what I've looked up, QComboBoxes can only have strings as items. If that's the case, is there a similar implementation that I can use?

I was hoping to do something like this

Answer 1

Look at this question, I think it is very similar if not identical to what you are looking for.

I hope this works for you.
