Java Swing Nimbus 外观和感觉中的手风琴

Question

While I was reading Oracle Swing documentation, I came across this example of a set of components displaying the Nimbus Look and Feel named SwingSet3 . I'm new to Swing. Can someone tell me if the accordion in the sidebar is a Swing component or not?

Answer 1

It is not a standard swing component.

You can have a look at the source code for the SwingSet3 demo here . The component on the left is a composite component made out of various other components such as JPanel , JLabel and JButton . There is a custom com.sun.swingset3.utilities.CollapsiblePanel too.

Answer 2

A similar component is the JXTaskPane/-Container which is part of SwingX You can have alook at a demo inspired by SwingSet3.

Note that SwingX is actively maintained, its current release 1.6.3 available at maven.java.net
