How to Use CardLayout with Netbeans GUI Builder

Introduction

Learning the intricacies of Netbeans GUI Builder can be a rewarding endeavor. One powerful layout manager it offers is CardLayout, which allows you to easily switch between multiple panels. This guide will walk you through the steps of using CardLayout with Netbeans GUI Builder.

Implementation Steps

1. Set Main Panel Layout: Begin by setting the layout of your main panel (mainPanel) to CardLayout. Right-click on the panel in the navigator and select "Set Layout -> CardLayout."
2. Add JPanels: Create additional JPanels to be used as cards in your CardLayout. Right-click on the mainPanel in the navigator and select "Add from Palette -> Swing Containers -> JPanel" three times.
3. Customize Panels: Differentiate between the panels by adding labels with unique names. Also, rename each panel's "Card Name" property in the properties pane to a corresponding name.
4. Add Button Listeners: Add action listeners to buttons that will switch between panels. Double-click on a button and in the "actionPerformed" event, insert code to change the visible panel.
5. Run and Test: Run your program and verify that the buttons correctly switch between the panels in the CardLayout.

Additional Tips

• You can drag and drop additional JPanel classes onto the main panel if desired.
• If you need to change the initial visible layout, right-click on the mainPanel and select "Change Order" to adjust the panel order.

With these steps, you can effectively use CardLayout to create flexible layouts that allow you to seamlessly navigate between different sections of your GUI.
