Java AWT tutorial for beginners. AWT stands for Abstract Window Toolkit. It is a platform dependent API for creating Graphical User Interface (GUI) for java programs. Why AWT is platform dependent? Determine If The Index Is Selected AWT List Example; Determine Multiple Selection Mode Of AWT List Example; Disable AWT List Example. The Abstract Window Toolkit (AWT). For example, creating an AWT check box would cause AWT directly to call the underlying native subroutine that created a check box. Home » Applets And AWT » AWT Frame. Create Frame Window Example; Create Frame Window With Window Close Event Example. Awt Example Programs In JavascriptJava AWT calls native platform (Operating systems) subroutine for creating components such as textbox, checkbox, button etc. For example an AWT GUI having a button would have a different look and feel across platforms like windows, Mac OS & Unix, this is because these platforms have different look and feel for their native buttons and AWT directly calls their native subroutine that creates the button. In simple, an application build on AWT would look like a windows application when it runs on Windows, but the same application would look like a Mac application when runs on Mac OS. AWT is rarely used now days because of its platform dependent and heavy- weight nature. AWT components are considered heavy weight because they are being generated by underlying operating system (OS). For example if you are instantiating a text box in AWT that means you are actually asking OS to create a text box for you. Awt Example Programs For WeddingSearch AWT's document library.

Swing is a preferred API for window based applications because of its platform independent and light- weight nature. Swing is built upon AWT API however it provides a look and feel unrelated to the underlying platform. It has more powerful and flexible components than AWT. In addition to familiar components such as buttons, check boxes and labels, Swing provides several advanced components such as tabbed panel, scroll panes, trees, tables, and lists. We will discuss Swing in detail in a separate tutorial. AWT hierarchy. Components and containers. All the elements like buttons, text fields, scrollbars etc are known as components. In AWT we have classes for each component as shown in the above diagram. To have everything placed on a screen to a particular position, we have to add them to a container. A container is like a screen wherein we are placing components like buttons, text fields, checkbox etc. In short a container contains and controls the layout of components. A container itself is a component (shown in the above hierarchy diagram) thus we can add a container inside container. Types of containers: As explained above, a container is a place wherein we add components like text field, button, checkbox etc. There are four types of containers available in AWT: Window, Frame, Dialog and Panel. As shown in the hierarchy diagram above, Frame and Dialog are subclasses of Window class. Window: An instance of the Window class has no border and no title. Dialog: Dialog class has border and title. An instance of the Dialog class cannot exist without an associated instance of the Frame class. Panel: Panel does not contain title bar, menu bar or border. It is a generic container for holding components. An instance of the Panel class provides a container to which to add components. Frame: A frame has title, border and menu bars. It can contain several components like buttons, text fields, scrollbars etc. This is most widely used container while developing an application in AWT. Java AWT Example. We can create a GUI using Frame in two ways: 1) By extending Frame class. By creating the instance of Frame class. Lets have a look at the example of each one. AWT Example 1: creating Frame by extending Frame classimport java. We have extended the Frame class here. 8) The java.awt package - Layout Objective 1) Write code using component container and layout manager classes of the java.awt package to present a GUI with specified. Java Abstract Window Toolkit. Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs. This part of the Java Swing tutorial we create first Java Swing programs. Java Swing first programs.
