designer 4.1 is only able to connect signals from existing widgets with
slots from existing widgets.

The most comfortable way to respond to signals of widgets that are
contained in the form you create is to use autoconnect, this means your
slots have to follow a specific naming convention which is
on_widget_signal(self, param1, param2, ...)
Where widget is the name of the widget that emits signal and the
param1-n are the parameters. Note that this feature of pyuic4 is pretty
new and thus needs some more work. For example QSpinBox emits 2
valueChanged signals and a slot called
gets called twice.
You never know how many friends you have until you rent a house on the beach.
