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
setToolTipTextmethod to register the text to display in a tool tip. The text displays when the cursor lingers over the component. - Use
getToolTipTextmethod to get the tooltip text. - Use
addto add the field in the frame.
Let’s see the code:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 | 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(); } }); }} |
This was an example on how to create JTextField with tooltip.
