Usually, if there’s a warning or error in your application GTK with print out an error to the console.
I would like GTK to print the warning/error out as a message box (e.g. GtkMessageDialog). How can I do that?

I’d like to test my application before I release it. During this “testing phase” I’d like every error to pop up directly, so I can see it, since I won’t use and monitor the console during this phase.
