NetBeans: Creating an Action object and attach it to one or more components on a form by IDE tools

Question

Because there is of no use manually edit the automatically Generated Code, how can I creat an Action object and attach this action to one or more components on a form?

Answer 1

• Right-click on the component, like a button
• in the pop-up menu select Events -> [Type of Event] -> method. Eg. Events -> Action -> actionPerformed

• Then you will see auto-generated code like

  private void jButton1ActionPerformed(java.awt.events.ActionEvent evt) {
      // write your code here
  }
  

• Netbeans will auto-generate the adding of a listener to the component, in the uneditable initComonents() that you can see.

If you have a custom Action class, you can always, in your GUI class constructor, add the Action object to the component right after the initComponents()
