One of previous message shows a way of doing clickable link on tooltip. see:
http://forum.java.sun.com/thread.jspa?threadID=592163&messageID=3093997
I modified the code a little bit to put tooltip on a button instead of panel.
import java.awt.BorderLayout;
import java.awt.Point;
import java.awt.event.MouseEvent;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.plaf.ToolTipUI;
public class HyperLinkToolTip extends JToolTip {
private JEditorPane theEditorPane;
public HyperLinkToolTip() {
setLayout(new BorderLayout());
LookAndFeel.installBorder(this, "ToolTip.border");
LookAndFeel.installColors(this, "ToolTip.background", "ToolTip.foreground");
theEditorPane = new JEditorPane();
theEditorPane.setContentType("text/html");
theEditorPane.setEditable(false);
theEditorPane.addHyperlinkListener(new HyperlinkListener() {
public void hyperlinkUpdate(HyperlinkEvent e) {
if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
// do whatever you want with the url
System.out.println("clicked on link : " + e.getDescription());
}
}
});
add(theEditorPane);
}
public void setTipText(String tipText) {
theEditorPane.setText(tipText);
}
public void updateUI() {
setUI(new ToolTipUI() {});
}
public static void main(String[] args) {
final JFrame frame = new JFrame(HyperLinkToolTip.class.getName());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
JButton btn = new JButton() {
public JToolTip createToolTip() {
JToolTip tip = new HyperLinkToolTip();
tip.setComponent(this);
return tip;
}
// Set tooltip location
public Point getToolTipLocation(MouseEvent event) {
return new Point(getWidth()/2, getHeight()/2);
}
};
btn.setText("Tooltip Test");
btn.setToolTipText("<html><body><a href=\"http://www.sun.com\">Goto www.sun.com for details.</a></body></html>");
panel.add(btn);
frame.setContentPane(panel);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
frame.setSize(400, 400);
frame.setVisible(true);
}
});
}
}
The code works fine in Java application. But, when I use it in an applet, it is almost impossible to click on the tooltip. The tooltip is flashing or disappears when trying to move mouse on the tooltip. I did set the location of tooltip to make sure there is no gap between button and tooltip. Here is the code for applet:
import java.awt.*;
import javax.swing.*;
import java.awt.event.MouseEvent;
public class ToolTipApplet extends JApplet {
private JPanel jContentPane = null;
private JButton btnTest = null;
public ToolTipApplet() {
super();
}
public void init() {
this.setSize(300, 200);
this.setContentPane(getJContentPane());
}
private JPanel getJContentPane() {
if (jContentPane == null) {
jContentPane = new JPanel();
jContentPane.setLayout(new FlowLayout());
jContentPane.add(getBtnTest(), null);
}
return jContentPane;
}
private JButton getBtnTest() {
if (btnTest == null) {
btnTest = new JButton() {
public JToolTip createToolTip() {
JToolTip tip = new HyperLinkToolTip();
tip.setComponent(this);
return tip;
}
// Set tooltip location
public Point getToolTipLocation(MouseEvent event) {
return new Point(getWidth()/2, getHeight()/2);
}
};
btnTest.setText("Tooltip Test");
btnTest.setToolTipText("<html><body><a href=\"http://www.sun.com\">Goto www.sun.com for details.</a></body></html>");
}
return btnTest;
}
}
No idea why application and applet behave differently here. (I am using JRE1.6u1 for the test.)
Thanks a lot!
