That’s done via signals and slots, a central Qt feature. [1] This is
very basic Qt; so I’d recommend you to read the tutorials,
documentation, help, examples, demonstrations and so on provided with Qt
and Qt Creator – they’re really great! You could e. g. start with the
Adressbook Tutorial [2]. Basically, the code would look like this:

  connect(fileDialog, SIGNAL(fileSelected(QString)),
      this, SLOT(slotFileSelected(QString)));

Furthermore, this is the Qt Creator mailing list – for general questions
on Qt (like this one), please use qt-interest. Thanks!

I hope this helps you.

Regards,
Robin
