| Hello World | ActionScript 3.0 |
My First Hello World Program in FlashBelow is the first program I ever wrote in ActionScript. It is a simple demonstration of some of the controls that are already available in the AS3 library.Click on the button in the upper left corner to see what happens - exciting! The code for this demo is presented at the bottom of the page. Note: All the graphics in this example are programmatically created at run time. The following is saved as "HelloWorld.as" and added as an object to the flash file.
package {
import flash.display.Sprite; import flash.text.TextField; import fl.controls.Button; import fl.events.ComponentEvent; import fl.controls.CheckBox; import fl.controls.List; public class HelloWorld extends Sprite { //Code will automatically run here... public function HelloWorld() : void {
var b : Button = new Button;
}b.label = "Click Me!"; addChild(b); b.addEventListener(ComponentEvent.BUTTON_DOWN, ButtonHandler); var c : CheckBox = new CheckBox; c.label = "Click here!"; c.y = 50; addChild(c); var l : List = new List; for (var i : int = 1; i <= 10; i++) {
l.addItem( { label: i.toString() } ); } l.x = 20; l.y = 100; l.rowCount = 8; addChild(l); private function ButtonHandler(e : ComponentEvent) {
var t : TextField = new TextField;
}t.text = "Hello World!"; t.x = 250; t.y = 250; addChild(t); removeEventListener(ComponentEvent.BUTTON_DOWN, ButtonHandler); } } |
