[maemo-developers] Noob question re Qt Application structure

[From: ianaré sévi]

I second that opinion. Subclassing by functionality is definitely good
for a single app, but if you need to have the two parts running at
different times a daemon app and a GUI app is the way to go.

Another option you could use to interact with your two apps is through
dbus itself, ince you will already be using that kind of code.
