Did you try hitting F4? this switches to the interactive signal/slot 
editor. The editor-widget was always just convinience, and it adds quite 
a lot of clutter (not sure there were other reasons to keep it up).

You can simple drag the widget you want to connect to get a visual 
connection hint (line). Drop that line on the widget you want to connect 
to and a dialog will open where you can set the respective signals and 
slots. This is imho a lot more intuitive.

Look at the code generated by uic (yourclass_ui.h). This shows you all 
the actions that are generated by designer. In your case, there is no 
alternative to that anyway, since designer has no concept of a 
QApplication, it only works in the scope of the dialog or widget you are 
editing, but you want to connect to a slot in the global QApplication 
Object (which you can reference via the global qApp pointer if you 
include the QApplication header).

Assuming you created an action called 'yourQuitAction': Simply edit the 
dialogs Constructor in the implementation. Then you can simply usa a 
"connect()" statement to wire ui.yourQuitAction (or 
ui->yourQuitAction)which you can simple connect to qApp's 
closeAllWindows() slot.

These are Qt basics however, better ask them on a pure Qt list or read 
the (excellent) online docs. This list is dedicated to Creator development.

Cheers,
