## Designing your user interface

To design a window, double-click a designable file in the project pane, such as `WelcomeFrame.java`. Then click the Design tab at the bottom of the AppBrowser. To add a component to your application, click a component on the component palette, then drop it where you want your component to appear in your user interface. Set the control's properties and events by double-clicking in the Inspector.

### Creating menus

To add a menu to your application, click the Design tab, then select a JMenuBar or JPopupMenu component from the Swing Containers page of the component palette.

Drop the component on the component tree. Then double-click the menu component in the component tree to start the menu designer so you can modify the menus and individual menu items.
