Basic AWT components
AWT: Abstract Window Toolkit
Its’s built-in platform-independent windowing, graphics, and user-interface widget toolkit. The java.awt is now part of the Java Foundation Classes (JFC). Which can be used for a graphical user interface (GUI) for a Java program. AWT consists of many classes which can be said: Components. A component is a class which can create a event specific GUI like TextField, Button, Label, Checkbox, TextArea, etc…
To add any component in Applet area, We have to call a add(Component c) method of Applet class. Which is discussed briefly in the below example.
import java.applet.*; import java.awt.*; public class componentDemo extends Applet { Button b; Label l; TextField tf; Scrollbar sb; TextArea ta; Checkbox c1,c2,c3; CheckboxGroup cbg = new CheckboxGroup(); public void init() { tf = new TextField("Ankit",20); l = new Label("First Name:"); b = new Button("Okay!"); ta = new TextArea(7,40); sb = new Scrollbar(Scrollbar.VERTICAL, 100, 20, 0, 200); sb.setPreferredSize(new Dimension(30,200)); c1 = new Checkbox("Cricket",true,cbg); c2 = new Checkbox("Hockey",false,cbg); c3 = new Checkbox("Football",false,cbg); add(l); add(tf); add(b); add(sb); add(ta); add(c1); add(c2); add(c3); } } /* <applet code="componentDemo" width="500" height="500"></applet> */
