I think this strategy is entirely fine! In a project with a similar need, we connected the ::currentChanged signal to a slot that calls a refresh() method of the corresponding widget. We then reimplemented this method for each widget to allow it to update itself in any way it wants. So I guess that is a similar solution. Your solution is cleaner since the WWidget::refresh() method also refreshes all strings to update themselves from the message resource bundles, which is not necessarily necessary. > I'd like to say again that I am really enjoying working with witty and I > am learning a lot fast :) Good to hear!
