Using the Flash Text Engine
Flash Text Engine example: News layout
Flash Player 10 and later, Adobe AIR 1.5 and later
This programming example shows the Flash Text Engine in use laying out a simple newspaper page. The page includes
a large headline, a subhead, and a multicolumn body section.
First, create an FLA file, and attach the following code to frame #2 of the default layer:
import com.example.programmingas3.newslayout.StoryLayout ;
// frame sc ript - create a 3-columned arti cle layout
var story:StoryLayout = new StoryLayout(720, 500, 3, 10);
story.x = 20;
story.y = 80;
addChild(story);
stop();
StoryLayout.as is the controller script for this example. It sets the content, reads in style information from an external
style sheet, and assigns those styles to ElementFormat objects. It then creates the headline, subhead and multicolumn
text elements.
package com.example.programmingas3.newslayout
{
import flash.display.Sprite;
import flash.text.StyleSheet;
import flash.text.engine.*;
import flash.events.Event;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.display.Sprite;
import flash.display.Graphics;
public class StoryLayout extends Sprite
{
public var headlineTxt:HeadlineTextField;
public var subtitleTxt:HeadlineTextField;
public var storyTxt:MultiColumnText;
public var sheet:StyleSheet;
public var h1_ElFormat:ElementFormat;
public var h2_ElFormat:ElementFormat;
public var p_ElFormat:ElementFormat;
private var loader:URLLoader;
public var paddingLeft:Number;
public var paddingRight:Number;
public var paddingTop:Number;
public var paddingBottom:Number;
public var preferredWidth:Number;
public var preferredHeight:Number;
public var numColumns:int;
public var bgColor:Number = 0xFFFFFF;
