Examples of AsyncPanel

com.mucommander.ui.layout.AsyncPanel

AsyncPanel is a JPanel aimed at components that potentially take a long time to initialize. It allows to deport their initialization in a separate thread as to not lock the event thread. It works as follows:

Initially, AsyncPanel displays a 'please wait component' that symbolizes the fact that the contents of the panel is being loaded.
When AsyncPanel becomes visible on screen, the {@link #getTargetComponent()} method is called to trigger theinitialization of the real component to display.
As soon as the method returns, the wait component is removed and the target component added to AsyncPanel. If AsyncPanel is the child of a java.awt.Window, the window is repacked to take into account the new size of this panel.

This panel tries to be as 'transparent' as possible for the target component: the borders of this panel are empty and its layout is a BorderLayout where the target component is added to the center.
