When a JButton is added to a content pane, we can set an action

  • 0

When a JButton is added to a content pane, we can set an action by double clicking the button or Right click->Event->Action->actionPerformed.Let say, we set somthing to happen. Then we need to remove that function.It can be done easily by deleting the code we wrote in that buttton’s actionPerformed. But the problem is, that button’s actionPerformed method is still there even though it is not used any more and not needed.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
   //no function here.. but this  code is still remaining. need to remove this code part as well
}

How can it be removed? I got the JButton for an example. Other components’action methods are like this.

    Go to your JButton properties, Choose “Events”, actionPerformed and choose “none” from the adjacent combobox. Your source code is cleaned!

    Netbeans Properties

    Recent versions of Netbeans like 7.3, do not offer “none” as an option, but allow you to delete the actionPerformed method by deleting the name of the method or by pressing 1, 2 and 3 buttons:
