Do not confuse it with the '''<tt>connect()</tt>''' function in the Berkeley socket library.
 This '''<tt>connect()</tt>''' call establishes a one-way connection between two Qt objects (objects that inherit [http://doc.qt.nokia.com/latest/qobject.html Qt::Object], directly or indirectly). Every Qt object can have both '''<tt>signals</tt>''' (to send messages) and '''<tt>slots</tt>''' (to receive messages). All widgets are Qt objects, since they inherit [http://doc.qt.nokia.com/latest/qwidget.html Qt::Widget], which in turn inherits [http://doc.qt.nokia.com/latest/qobject.html Qt::Object].
 Here, the '''<tt>clicked()</tt>''' signal of '''<tt>quit</tt>''' is connected to the '''<tt>quit()</tt>''' slot of '''<tt>app</tt>''', so that when the button is clicked, the application quits.
 The [http://doc.qt.nokia.com/latest/signalsandslots.html Signals and Slots] documentation describes this topic in detail.
