In one word: Don't! Designer is really the BADEST python development 
environment available. Don't do this in designer at all.

Create your UI in designer. Create another python module, import and 
subclass your UI module (eric has an option in the context menu of UI 
modules for exact this purpose). Now you have maximum control about 
your UI, and does your real work in powerful development environment 
with all powers at your hand.

No, you aren't looking for a signal, you're looking for the polish 
method. Don't forget to call the polish baseclass method and be aware, 
that Qt may call polish more than once..

BTW Lajos, it would be nicer for us, if you configure your MUA to 
display your full name.
