JTextField

Create JTextField with tooltip

With this example we are going to learn how to create a JTextField with a tootip. Tooltip texts are very useful because they explain to the users how to use a specific component.

It’s very easy to set a tooltip text in a JTextField as all you have to do is:

  • Create a class that extends JFrame.
  • Create a new JTextField.
  • Use setToolTipText method to register the text to display in a tool tip. The text displays when the cursor lingers over the component.
  • Use getToolTipText method to get the tooltip text.
  • Use add to add the field in the frame.

Let’s see the code:

package com.javacodegeeks.snippets.desktop;

import java.awt.FlowLayout;

import javax.swing.JFrame;
import javax.swing.JTextField;

public class CreateJTextFieldWithTooltip extends JFrame {

	private static final long serialVersionUID = 1L;

	public CreateJTextFieldWithTooltip() {

		// set flow layout for the frame
		this.getContentPane().setLayout(new FlowLayout());

		// create JTextField
		JTextField field = new JTextField();
		field.setText("Java Code Geeks");

		// Registers the text to display in a tool tip.
	    // The text displays when the cursor lingers over the component.
		field.setToolTipText("This is the textfield's tooltip");

		String tooltipText = field.getToolTipText();

		System.out.println("Tooltip Text: " + tooltipText);

		// add textfield to frame
		add(field);

	}

	private static void createAndShowGUI() {

  //Create and set up the window.

  JFrame frame = new CreateJTextFieldWithTooltip();

  //Display the window.

  frame.pack();

  frame.setVisible(true);

  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

	public static void main(String[] args) {

  //Schedule a job for the event-dispatching thread:

  //creating and showing this application's GUI.

  javax.swing.SwingUtilities.invokeLater(new Runnable() {

public void run() {

    createAndShowGUI(); 

}

  });
    }

}
