In our case we want to know when the button is pressed, either by mouse click or via keyboard. So we will use ActionListener responding to ActionEvent.

Right click the Exit button. Note that the menu contains many more events you can respond to! The IDE will open up the Source Code window and scroll to where you implement the action you want the button to do when the button is pressed either by mouse click or via keyboard. Your Source Code window should contain the following lines:. We are now going to add code for what we want the Exit Button to do. Your finished Exit button code should look like this:.

Right click the Clear button jButton1. We are going to have the Clear button erase all text from the jTextFields. To do this, you will add some code like above.

Your finished source code should look like this:. The above code changes the text in all three of our JTextFields to nothing, in essence it is overwriting the existing Text with a blank. It is going to accept user input from jTextField1 and jTextField2 and convert the input from a type String to a float.

And finally, it will convert the sum to a type String and place it in jTextField3. Lets get started! Right-click the Add button jButton2. We are going to add some code to have our Add button work. The finished source code shall look like this:. This tutorial has showed how to respond to a simple button event. There are many more events you can have your application respond to. Go back to the file NumberAdditionUI. Right-click any GUI component, and select Events from the pop-up menu.

Alternatively, you can select Properties from the Window menu. In the Properties window, click the Events tab. In the Events tab, you can view and edit events handlers associated with the currently active GUI component. You can have your application respond to key presses, single, double and triple mouse clicks, mouse motion, window size and focus changes. You can generate event handlers for all of them from the Events menu. The most common event you will use is an Action event.

How does event handling work? Every time you select an event from the Event menu, the IDE automatically creates a so-called event listener for you, and hooks it up to your component. Go through the following steps to see how event handling works. These methods are called event handlers. Now scroll to a method called initComponents. First, note the blue block around the initComponents method.
