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

问题

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.

回答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.

回答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.
