Java language support Table 3.1 Navigation keyboard shortcuts (continued) Keyboard shortcut Action Enter or Project and structure pane - expands and collapses top level Left / Right arrows tree node branches. Enter Project pane - opens a selected source file and places cursor in Source view. This is equivalent to a double-click. Structure pane - drills down into the superclass or interface of the selected class. This is equivalent to a double-click. For more information, see the Navigating and searching in the AppBrowser topic in The JBuilder environment chapter of Building Applications with JBuilder. Java language support More than any other Java development environment, JBuilder gives you easy access to the programming power of the Java language. When you re developing cutting-edge applications, you need the most efficient tools available to simplify your programming. JBuilder provides the tools and language support you need for developing your applications. JBuilder includes the following language support: JavaBeans for reusable components JFC/Swing components for Java user interface development JBuilder Professional includes language support for JDBC Servlets Multiple Java Development Kits (JDKs) JBuilder starts RMI registry and can compile using RMIC. JBuilder allows you to build applications and applets for different versions of the JDK from JDK 1.1x on up. Any existing 100% Java 2 compliant program can be added to, worked on, and run from the JBuilder environment. Select Project|Project Properties and the Paths tab to change the JDK version to compile against. For more information, see http://www.javasoft.com. JBuilder Enterprise includes language support for Enterprise JavaBeans (EJB) for server-side component architecture and EJBExpress for visually creating Enterprise JavaBeans CORBA JavaServer Pages (JSP) for web-based applications 3-6 Learning Java with JBuilder

Introducing the AppBrowser AppBrowser design view You can use the UI designer to design your application visually. To view a file in the UI designer, select the Design tab at the bottom of the content pane. The design view for the file is displayed and the component palette, available only in the design view, appears at the top of the content pane. To create a UI, drag and drop components from the component palette in the content pane or in the structure pane on the appropriate node. The resulting code is automatically generated and inserted into your file. Use the Inspector to adjust the properties of the components you choose.

Introducing the AppBrowser These elements of the AppBrowser perform the following functions: AppBrowser element Description Main menu bar Provides access to many menus, such as File, Edit, Search, Run, and Wizards. Main toolbar Composed of small toolbars grouped by functionality. Buttons on the toolbar provide shortcuts to commands. Project pane Displays the contents of the project currently selected from the project drop-down list. The project tree can be navigated and manipulated without opening files. Project toolbar Contains a drop-down list of currently open projects and buttons for adding and removing files, closing the project, and refreshing the project files in the project pane. Structure pane Contains icons, sort options, and error display. Supports JavaDoc @todo tags. The structure pane shows the structure of the file currently selected in the content pane. For a Java file, this structure is displayed in the form of a tree showing all the methods, properties, and events defined in the file. The structure pane provides a drill-down feature. Double-click a class or interface to see its ancestor. Other file types may have their structure displayed differently. Content pane Where open files are viewed. Each open file has a tab that displays the file name (file tab) and tabs at the bottom for its different available views (file view tabs). File view tabs Allow you to change the view of the content pane to source, design, bean, doc, or history view. File tabs Display the names of open files. Only the file tabs of the active project are shown. To view an open file, select its file tab. Message pane A tabbed display area for messages from subsystems, such as designers, search results, and compiler, debugger, and runtime processes. The message pane is visible when these subsystems are activated. It also houses the debugger user interface. Status bars Keep you updated on any processes and their results. There are three status bars. The main status bar is displayed at the bottom of the AppBrowser window. The file status bar is displayed at the bottom of the open file in the source view of the content pane. The message status bar is displayed at the bottom of the message pane, above the message tab. The AppBrowser can be customized using the OpenTools API. For more information on one of the items above, search for the item you want to know about in the online help. Introducing JBuilder 3-3
