Display multiple lines of text in a component’s tooltip with Java
Let’s first see how we set text in a components tooltip −
JLabel label3 = new JLabel("Password", SwingConstants.CENTER);
label3.setToolTipText("Enter Password");
To display multiple lines of text in a tooltip, use <html>. Here, we have used the HTML <br> tag for new line and that would create multiple lines of text in the tooltip −
label3.setToolTipText("<html>" + "This will create multiple lines for the" + "<br>" + "component! Yay!" + "</html>");
The following is an example to display multiple lines of text in a component’s tooltip −
Example
package my;
import java.awt.GraphicsEnvironment;
import java.awt.GridLayout;
import java.awt.Point;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
import javax.swing.ToolTipManager;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("Register!");
JLabel label1, label2, label3;
frame.setLayout(new GridLayout(2, 2));
label1 = new JLabel("Id", SwingConstants.CENTER);
label1.setToolTipText("<html>" + "Add the id given to you" + "<br>" + "in the beginning!" + "</html>");
label2 = new JLabel("Rank", SwingConstants.CENTER);
label2.setToolTipText("Enter rank");
label3 = new JLabel("Password", SwingConstants.CENTER);
label3.setToolTipText("Enter Password");
ToolTipManager.sharedInstance().setEnabled(false);
JTextField emailId = new JTextField(20);
JTextField rank = new JTextField(20);
JPasswordField passwd = new JPasswordField();
passwd.setEchoChar('*');
frame.add(label1);
frame.add(label2);
frame.add(label3);
frame.add(emailId);
frame.add(rank);
frame.add(passwd);
Point center = GraphicsEnvironment.getLocalGraphicsEnvironment().getCenterPoint();
int width = 500;
int height = 200;
frame.setBounds(center.x - width / 2, center.y - height / 2, width, height);
frame.setVisible(true);
}
}
The output is as follows. Here, we are displaying the multi-line tooltip text visible on mouse hover −
