Just an idea for overloaded methods:

IMO you could add something like this:

public class ActivatedEventArgs : EventArgs
{
    public int index { get; set; }
    public string text { get; set; }
}

and to the QComboBox class something like this:

public event EventHandler<ActivatedEventArgs> Activated;

then you can do :

myComboBox.Activated += new
EventHandler<ActivatedEventArgs>(myComboBox_Activated);

which will send both the index and the text for the QComboBox when
activated (which personally I think it is better than sending those
values separate).

I think that will be a much better solution than the current
"this.Connect" stuff a whole lot more elegant and very C#ish.

Just my 2 cents.
