In this example we are going to see how to retrieve information about the display of your device. With this example we shall show you how stroke or fill a simple graphic component with a texture.

Stroking or Filling with a Texture example.

This is very useful when you have many graphical objects firing up at the start up of your application. With this example we shall show you how to set the component that gets the focus when your application starts up.

Setting the initial focus component in a Window.

You might want to use the bell in terminal based apps to get the user’s attention when something important happens to the program. In this tutorial we are going to show you how to use the Terminal bell in a Java program. With this tutorial we are going to see how to list all available font families in your environment using Java. We are going to use some the built in classes that Java offers. In this tutorial we shall show you how to create a simple graphic by combining basic shapes. With this example will shall show you four fundamental graphical transformations that you should know when you try to construct you own custom graphical environment or develop simple graphics. Scaling Shearing Translating Rotating a Shape.We are going to use some basic classes from AWT. In this tutorial we are going to show how you can print simple shapes in paper using your printer. In this tutorial we shall show you how to construct a simple graphic by creating basic shapes. AWT Tutorials – Getting Started Simple examples based on AWT A DirectFB backend for Caciocavallo is under development, as is an HTML5 backend the aim is to deploy existing Swing applications-without Java support-as ordinary web applications running on a web server. All the necessary core-JDK modifications have since been pushed to OpenJDK 7, which means that Java can now be used on a graphics stack other than one of those provided by the official JDK (X Window System, OpenGL or DirectX), by including an external library and setting some system properties. The project has successfully implemented AWT widgets using Java2D. ImplementationĪs the AWT is a bridge to the underlying native user-interface, its implementation on a new operating system may involve a lot of work, especially if it involves any of the AWT GUI widgets, because each of them requires that its native peers be developed from scratch.Ī new project, Caciocavallo, has been created, that provides an OpenJDK-based Java API to ease AWT implementation on new systems.

Starting in Java 6 Update 12, it is possible to mix Swing and AWT widgets without having z-order problems. This problem was because the rendering architecture of the two widget toolkits was very different, despite Swing borrowing heavyweight top containers from AWT. Prior to Java 6 Update 12, mixing Swing components and basic AWT widgets often resulted in undesired side effects, with AWT widgets appearing on top of the Swing widgets regardless of their defined z-order. To address this problem, a utility class called SwingWorker allows applications to perform time-consuming tasks following user-interaction events in the event dispatching thread. Failure to do so may result in a deadlock or race condition.

Therefore, code that updates the GUI or processes events should execute on the Event dispatching thread. Neither AWT nor Swing are inherently thread safe.

The ability to launch some desktop applications such as web browsers and email clients from a Java application.

Access to the system tray on supporting systems.

It also provides the AWT Native Interface, which enables rendering libraries compiled to native code to draw directly to an AWT Canvas object drawing surface.ĪWT also makes some higher level functionality available to applications, such as:

A package for use with the Clipboard and Drag and Drop.Ī basic set of GUI widgets such as buttons, text boxes, and menus.

The interface to input devices such as mouse and keyboard.

The interface between the native windowing system and the Java application.

This API is at the core of Java GUI programming and is also used by Swing and Java 2D. ArchitectureĪ general interface between Java and the native system, used for windowing, events, and layout managers. For example, Connected Device Configuration profiles require Java runtimes on mobile telephones to support the Abstract Window Toolkit. AWT is also the GUI toolkit for a number of Java ME profiles. The AWT is part of the Java Foundation Classes (JFC) - the standard API for providing a graphical user interface (GUI) for a Java program. The Abstract Window Toolkit ( AWT) is Java’s original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing.

In this detailed Resource page, we feature an abundance of AWT Tutorials!
