The meta-object compiler (moc) generates the glue code for signals and slots. The UI editor just handles the connections and emits the necessary stuff to the ui file. Uic compiles these things into c++ headers which are then used my moc.

It's there, usually by the end of setupUi method. Just look better.

For instance, this chunk in the .ui

 <connections>
  <connection>
   <sender>checkBox</sender>
   <signal>toggled(bool)</signal>
   <receiver>checkBox_2</receiver>
   <slot>setChecked(bool)</slot>
  </connection>
 </connections>

Results in

QObject::connect(checkBox, SIGNAL(toggled(bool)), checkBox_2, SLOT(setChecked(bool)));

in the generated header.
