where is the generated code of "Qt Signals/Slots editor"?

Question

QtCreator 2.7.2 ,I use the Qt Creator design a connection and i can see it in the file *.ui ,but I can't find it in the generated file ui_*.h after build, where is it ? I'm curious.

Answer 1

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.

Answer 2

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.
