The last line of the setupUi function that uic generates is:

        QMetaObject::connectSlotsByName(<object var>);

<http://qt-project.org/doc/qt-4.8/qmetaobject.html#connectSlotsByName> says:

Searches recursively for all child objects of the given object, and connects 
matching signals from them to slots of object that follow the following form:

 void on_<object name>_<signal name>(<signal parameters>);

Let's assume our object has a child object of type QPushButton with the object 
name button1. The slot to catch the button's clicked() signal would be:

 void on_button1_clicked();
