Explanation
- This is the spring box on the left. Just for illustration sake, we use a hbox here to show you that the effect is the same as using an empty GtkLabel.
- This is the spring box on the right. Just for illustration sake, we use a vbox here to show you that the effect is the same as using an empty GtkLabel.
