有不同的方法可以做到这一点。一种方法是简单地避免插入符号可见性调整，如下所示：
import java.awt.Rectangle;
import javax.swing.JButton;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
import javax.swing.text.DefaultCaret;
public class TestEditorPane implements HyperlinkListener {
private final class MyCaret extends DefaultCaret {
@Override
protected void adjustVisibility(Rectangle nloc) {
}
}
JEditorPane dataDisplayer = new JEditorPane();
private MyCaret caret;
@Override
public void hyperlinkUpdate(HyperlinkEvent arg0) {
dataDisplayer.setText("<a href=''>Change Text</a><br><br><br><br><br><br><br><br><br><br>bla bla");
}
public void init() {
JFrame frame = new JFrame();
dataDisplayer.setEditable(false);
caret = new MyCaret();
dataDisplayer.setCaret(caret);
dataDisplayer.add(new JButton());
dataDisplayer.setContentType("text/html");
JScrollPane jsp = new JScrollPane(dataDisplayer);
dataDisplayer.setText("<a href=''>Change Text</a><br><br><br><br><br><br><br><br><br><br>bla");
this.dataDisplayer.addHyperlinkListener(this);
frame.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(jsp);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokelater(new Runnable() {
@Override
public void run() {
new TestEditorPane().init();
}
});
}
}
