Class DelegatingBorder

java.lang.Object

javax.swing.border.AbstractBorder

org.rspeer.commons.DelegatingBorder

All Implemented Interfaces:

Serializable, Border

public class DelegatingBorder
extends AbstractBorder

A self-installing border that wraps another Border (e.g., TitledBorder) and overlays a real Swing component as a child inside the border. No explicit install() needed.

Usage: TitledBorder titled = BorderFactory.createTitledBorder("Dataset"); DelegatingBorder border = new DelegatingBorder( titled, () -> { JLabel sub = new JLabel("ⓘ"); sub.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); sub.setToolTipText("Click for details"); sub.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { JOptionPane.showMessageDialog(SwingUtilities.getWindowAncestor(sub), "Clicked!"); } }); return sub; }, DelegatingBorder.Anchor.SOUTH_EAST, new Insets(4,6,4,6) ); panel.setBorder(border);
