Before starting this blog I picked up a new book, “clear blogging” by Bob Walsh published by Apress. I like it so far but I haven’t finished reading it. I felt I needed some hands on experience at the same time. However, I’m going to start exercising one of his points and that is to blog about topics I love. One topic I love is “programming style”.
This is the ActionScript 3 code I used to measure the SWF file size in my previous post:
EFD1.as
package
{
import flash.display.Sprite;
import display.Header;
public class EFD1 extends Sprite
{
/* --------------------------------------------------------------------
Constructor
-------------------------------------------------------------------- */
public function EFD1
()
{
var lvHeader:Header = new Header
(
200,
[0x8A39B9, 0x9D5BBF],
"Shop by Category"
);
addChild( lvHeader );
} // Constructor
} // class EFD1
} // package
Header.as
package display
{
import flash.display.*;
import flash.text.TextField;
import flash.geom.*
public class Header extends Sprite
{
/* --------------------------------------------------------------------
Private Static Variables
-------------------------------------------------------------------- */
// Programmers looking at my code:
// Please don't do what I've done here. That is, don't declare these
// as static variables. I did this when I was testing how much memory
// is used. Although this technique works and is expedient, it will
// end up biting you later on.
private static var svCorner :Number = 5;
private static var svHeight :Number = 18.0;
private static var svIndent :Number = 5;
private static var svMargin :Number = 2;
private static var svTextColor :uint = 0xFFFFFF;
/* --------------------------------------------------------------------
Private Member Variables
-------------------------------------------------------------------- */
private var mvTextField :TextField;
/* --------------------------------------------------------------------
Constructor
-------------------------------------------------------------------- */
public function Header
( avWidth :Number,
avColors :Array,
avText :String = "" )
{
super();
var lvWidth:Number = avWidth - svMargin - svMargin;
//Add Gradient Header
var lvMatrix:Matrix = new Matrix();
lvMatrix.createGradientBox( lvWidth, svHeight, Math.PI * .5, 0, 0);
graphics.beginGradientFill
(
GradientType.LINEAR,
avColors,
[1, 1],
[0x0, 0xFF],
lvMatrix,
SpreadMethod.PAD
);
graphics.drawRoundRect( svMargin, svMargin, lvWidth, svHeight, svCorner );
// Add TextField
mvTextField = new TextField();
mvTextField.x = svMargin + svIndent;
mvTextField.y = svMargin;
mvTextField.width = lvWidth - svIndent - svIndent;
mvTextField.height = svHeight;
mvTextField.textColor = svTextColor;
mvTextField.selectable = false;
setText( avText );
addChild( mvTextField );
} // Constructor
/* --------------------------------------------------------------------
setText
-------------------------------------------------------------------- */
public function setText
( avText :String )
:void
{
mvTextField.text = avText;
} // setText
} // class Header
} // package display
Code produces EFD1.swf
