Question

Hi again fellow Flashers 🙂

My first question poised here at StackOverFlow dealt with this issue, I had an array which created a few different buttons. However I didn’t know how to assign actions to them:
How to give dynamically created buttons actions for each one – part 1

Thanks to Joel Hooks, I was able to get my code working. However this time around instead of using an imported graphic as a Class from my library, I’m instead creating a movieClip by drawing a gradient*(didn’t need to import a jpg)*. Now I’m getting another dreaded “not compile time constant” error again. I believe it has something to do with how I’m trying to determine the button instance that is clicked or rolledOver.

The Previous button creation (working) code:

for (var i:Number=0; i < myXMLArray.length; i++) {
navButton=new NavButton ;
navButton.name=”button” + i;
navButton.x=i * navSIZE;
navButton.y=navBtnY;
navButton.buttonMode=true;
thumbsMov.addChild(navButton);

buttons.push(navButton);
buttons[i].addEventListener(MouseEvent.MOUSE_UP,handleButtonClick);
buttons[i].addEventListener(MouseEvent.ROLL_OVER,handleButtonOver);
buttons[i].addEventListener(MouseEvent.ROLL_OUT,handleButtonOff);
}

The Previous listener (working) code:

function handleButtonOver(event:MouseEvent):void {

var button:NavButton = event.target as NavButton;
var id:Number = Number(button.name.split(“button”)1);
if(button)
TweenLite.to(buttonRolls[id], .4, {alpha:1, ease:Strong.easeOut});
cataText[id].defaultTextFormat = a12Green;
cataText[id].text = myXMLArray[id].id;
}

Current button creation code:

for (var i:Number = 0; i < num; i++) {
trace("loop number = "+i);

var blueGradient:MovieClip = new MovieClip();
 blueGradient.name = "button" +i;
 blueGradient.graphics.beginGradientFill(bGrad, bColors, bAlphas, bRatios ,bMatrix)
 blueGradient.graphics.drawRect(0, 0, 266, 40);
 blueGradient.x = i * navSIZE;
 blueGradient.y = navBtnY;
 blueGradient.buttonMode = true;
addChild(blueGradient);

buttons.push(blueGradient)

buttons[i].addEventListener(MouseEvent.MOUSE_UP, handleButtonClick);
buttons[i].addEventListener(MouseEvent.ROLL_OVER, handleButtonOver);
buttons[i].addEventListener(MouseEvent.ROLL_OUT, handleButtonOff);

}

Current button listener code:

function handleButtonOver(event:MouseEvent):void {
var button:blueGradient = event.target as blueGradient;
var id:Number = Number(blueGradient.name.split("button")[1]);
if(blueGradient)
 cataText[id].defaultTextFormat = navFontRoll;
 cataText[id].text = myArray[id].id;

}

The current movie will only run without an error if the following line is commented out:

var button:blueGradient = event.target as blueGradient;

Because that is what is causing the not compile time constant error to come up. However by removing that line, all buttons are button1 instead of 2 buttons dynamically created named button0 and button1.

Any help or pointers here would be greatly appreciated! Thanks in advance for taking a look at my code.

I think, since the as keyword is for casting, you want this line instead:

var button:MovieClip = event.target as MovieClip;

blueGradient seems to be a variable name, not a class name.
