BasicMessagePaneUI provides a means to place an icon, message and buttons into a Container. The layout will look like:<p> <pre> ------------------ | i | message | | c | message | | o | message | | n | message | ------------------ | buttons | |________________| </pre> icon is an instance of Icon that is wraped inside a JLabel. The message is an opaque object and is tested for the following: if the message is a Component it is added to the Container, if it is an Icon it is wrapped inside a JLabel and added to the Container otherwise it is wrapped inside a JLabel. <p> The Container, message, icon, and buttons are all determined from abstract methods.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><A
