Layout Managers

A layout manager is an object that positions and resizes the components in an AWT container according to some algorithm; for example, GridLayout lays out components in rows and columns. The layout managers provided with the AWT cover most GUI designs that you are likely to build--FlowLayout, BorderLayout, CardLayout, and GridLayout are covered. This course also covers the RatioLayout manager, which is useful when you need to specify position or size as a ratio of the width or height of a Container.
