[PyQt] Creating custom widget for designer

[Jorge Tornero]

Dear all,
I've created a  custom widget which can be used from within designer-qt4,
following the few recipes available out there.

It works as expected but, because I'm not a pro, I'm looking for some
advice on the way I've implemented the widget.

Basically: the base class is a QLineEdit in which a key event triggers a
Qdialog which has customized QComboBox inside. Therefore I've implemented
the widget as a single  class in this fashion (simplified)

class myLineEdit(QLineEdit):
   class myPopupDialog(QDialog):

        class myCustomCombo(QComboBox):
               (Definition of myCustomCombo goes here)
       (Definition of mypopupdialog goes here, including some customcombos)

    (Defi ition of mylineedit goes here including key event handler
that execs a mypopupdialog)

This, say so, class-!nesting schema is very strange to me, so let me
ask you if this is a correct way of implementing such widgets,
providing they're going to be used as designer plugins.

Thank you very much for your advice


All the best

Jorge Tornero
