Adding Drag-and-Drop Support to a JLabel Component</h3>
This example demonstrates how to modify a label component so that its
text can be dragged and dropped to another component.
<pre>
// Create a label
JLabel label = new JLabel(<font color="#0066ff"><i>"Label Text"</i></font>);
// Specify that the label's text property be transferable; the value of
// this property will be used in any drag-and-drop involving this label
final String propertyName = "text";
label.setTransferHandler(new TransferHandler(propertyName));
// Listen for mouse clicks
label.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent evt) {
JComponent comp = (JComponent)evt.getSource();
TransferHandler th = comp.getTransferHandler();
// Start the drag operation
th.exportAsDrag(comp, evt, TransferHandler.COPY);
}
});
</pre>
