[PySide] how to sort QTableWidget when cell widgets are used?

[Frank Rueter | OHUfx]

Hi everyone,

I'm pretty new to QT/Pyside and am trying to create a simple table that 
has checkboxes and dropdown menus for cell widgets.
Now I'm wondering how I could sort the respective columns that contain 
such widgets (sorting by their respective values).

Here is an example of the code I've got, which gives you a string field 
(default), a dropdown and a checkbox widget for each row.
I'd like to be able to sort all three columns:

Any help would be greatly appreciated!
