I would like to know when the QT application has finished loading so I can start doing some stuff.

I do not know if I'm thinking about this in the wrong way but I want to run a function when the application has finished loading and the only way I can think of is to make a connection between some event and my function but I do not seem to be able to find any good event for this.

Please advice.

(Qt 4.6, Windows, GUI app with one form)
