A very common use of GtkLabel is to display
text that describes or makes some comment about the use of an
adjacent widget. If you need to display a great deal of text, use
GtkText instead.
Note that labels do not generate events. If you want to catch events
(e.g. from a mouse click) you will need to put the label in a
GtkEventBox.
