You can still do the same thing, except that you'll additionally need a
python class subclassing QMainWindow that loads the ui from the designer
form. Then you can create subclasses from that and set the central
widget. If the form is a member of your base class you can also access
it and all widgets from the subclass.


You have an unusual magnetic personality.  Don't walk too close to
metal objects which are not fastened down.
