	Chapter 5. Dialogs

A Hildon::Banner is a small popup window at the top of the screen which can display text, either with or without markup. The window will be hidden automatically after a certain amount of time.

The Banner cannot be directly instantiated. Instead you should call the static methods, such as show_information() and show_information_with_markup() to show a Banner.

Example
