Here, we are showing Button component on the Frame. Let's see a simple example of AWT where we are inheriting Frame class. By creating the object of Frame class ( association).By extending Frame class ( inheritance).There are two ways to create a GUI using Frame in AWT. To create simple AWT example, you need a frame. Sets the size (width and height) of the component.ĭefines the layout manager for the component.Ĭhanges the visibility of the component, by default false. Public void setSize(int width,int height) Frame is most widely used container while developing an AWT application. It can have other components like button, text field, scrollbar etc. The Frame is the container that contain title bar and border and can have menu bars. An instance of Panel class creates a container, in which we can add components. It can have other components like button, text field etc. It is generic container for holding the components. The Panel is the container that doesn't contain title bar, border or menu bar. We need to create an instance of Window class to create this container. You must use frame, dialog or another window for creating a window. The window is the container that have no borders and menu bars. There are four types of containers in Java AWT: Note: A container itself is a component (see the above diagram), therefore we can add a container inside container. Thus it contains and controls the layout of components. It is basically a screen where the where the components are placed at their specific locations. The classes that extends Container class are known as container such as Frame, Dialog and Panel. The Container is a component in AWT that can contain another components like buttons, textfields, labels etc. In order to place every component in a particular position on a screen, we need to add them to a container. In Java AWT, there are classes for each component as shown in above diagram. ComponentsĪll the elements like the button, text fields, scroll bars, etc. The hierarchy of Java AWT classes are given below. PDF MAC OS X FOR JAVA GEEKS WINDOWSIn simple words, an AWT application will look like a windows application in Windows OS whereas it will look like a Mac application in the MAC OS. The reason for this is the platforms have different view for their native components and AWT directly calls the native subroutine that creates those components. Java AWT calls the native platform calls the native platform (operating systems) subroutine for creating API components like TextField, ChechBox, button, etc.įor example, an AWT GUI with components like TextField, label and button will have different look and feel for the different platforms like Windows, MAC OS, and Unix. The AWT tutorial will help the user to understand Java GUI programming in simple and easy steps. The java.awt package provides classes for AWT API such as TextField, Label, TextArea, RadioButton, CheckBox, Choice, List etc. its components are using the resources of underlying operating system (OS). components are displayed according to the view of operating system. Java AWT components are platform-dependent i.e. Java AWT (Abstract Window Toolkit) is an API to develop Graphical User Interface (GUI) or windows-based applications in Java.
