AFAIK QtCreator uses the QMetaObject::connectSlotsByName to connect the slots 
created with the designer. So if you create a slot on_<component>_<signal> with 
a correct signature it will work. Unfortunately it places the cursor behind the 
slot instead of inside, once ithe slot is created not matter whether it was 
created manually or by the designer itself.

By the way. I like the way (Borland|Inprise|CodeGear|Embarcadero) Delphi handle 
this since version 1.0 (1995 AFAIR). Maybe the trolls want to have a look at it 
to get some inspiration. It works like the property sheet and lists all possible 
slots (events in Delphi-speak) or just creates a new one, if you type in the 
name of an unknown and press enter. Of course this works both way,s from 
property editor to code and backwards.
