Using the Flash Text Engine
The mouseOverHandler() and mouseOutHandler() functions set the cursor to a button cursor when it's over the
word "here" and back to an arrow when it's not.
Formatting text
Flash Player 10 and later, Adobe AIR 1.5 and later
A TextBlock object is a factory for creating lines of text. The content of a TextBlock is assigned via the TextElement
object. An ElementFormat object handles the formatting for the text. The ElementFormat class defines such
properties as baseline alignment, kerning, tracking, text rotation, and font size, color, and case. It also includes a
FontDescription, which is covered in detail in “Working with fonts” on page 409.
Using the ElementFormat object
Flash Player 10 and later, Adobe AIR 1.5 and later
The constructor for the ElementFormat object takes any of a long list of optional parameters, including a
FontDescription. You can also set these properties outside the constructor. The following example shows the
relationship of the various objects in defining and displaying a simple text line:
package
{
import flash.display.Sprite;
import flash.text.*;
}
public class ElementFormatExample extends Sprite
{
private var tb:TextBlock = new TextBlock();
private var te:TextElement;
private var ef:ElementFormat;
private var fd:FontDescription = new FontDescription();
private var str:String;
private var tl:TextLine;
}
public function ElementFormatExample()
{
fd.fontName = "Garamond";
ef = new ElementFormat(fd);
ef.fontSize = 30;
ef.color = 0xFF0000;
str = "This is flash text";
te = new TextElement(str, ef);
tb.content = te;
tl = tb.createTextLine(null,600);
addChild(tl);
}
