[Bindable][Embed(”assets/iconset/save.png”)]
public var saveIcon:Class;

————————————————–
var iconSource:String = “saveIcon”;

var ImageClass:Class = this[iconSource] as Class;
button.setStyle(“icon”, ImageClass);

e.g.

[Bindable][Embed("assets/iconset/save.png")]
public var saveIcon:Class;

How do we include a dynamic reference? Say, I have my own component called “MyButton”, which is dynamically loaded from database or xml file at runtime. In another word, I don’t the class name of my component at the coding/compiling time

It took me about 5 hours to figure this one out.

You rock!

Andrew.

Try using main.getChildByName() instead:

var i:Image = main.getChildByName("54237") as Image;

This is my code in a nutshell:

The following code is in a loop where “contentType” changes between Text, TextArea and Image. It outputs perfectly (thanks to you!).

var c:Class = getDefinitionByName('mx.controls.'+contentType) as Class;
var obj:UIComponent = new c();

if (obj) {
switch (obj.className) {
    case "Text":
        Text(obj).id = contentID;
        Text(obj).text = content;
        Text(obj).x = contentxPos;
        Text(obj).y = contentyPos;
        Text(obj).width = contentWidth;
        Text(obj).height = contentHeight;
        Text(obj).styleName = contentStyleName;
        break;
    case "TextArea":
        TextArea(obj).id = contentID;
        TextArea(obj).text = content;
        TextArea(obj).x = contentxPos;
        TextArea(obj).y = contentyPos;
        TextArea(obj).width = contentWidth;
        TextArea(obj).height = contentHeight;
        TextArea(obj).styleName = contentStyleName;
        break;
    case "Image":
        Image(obj).name = "54237";
        Image(obj).id = contentID;
        Image(obj).source = contentSource;
        Image(obj).x = contentxPos;
        Image(obj).y = contentyPos;
        Image(obj).width = contentWidth;
        Image(obj).height = contentHeight;
        Image(obj).setStyle('completeEffect', slowFade);
        Image(obj).addEventListener(MouseEvent.CLICK, showImageGallery);
        Image(obj).addEventListener(FlexEvent.CREATION_COMPLETE, creationCompleteHandler);
        break;
}
main.addChild(obj);
}

…but then I use:

var i:Image = getChildByName("54237") as Image;
i.source = '/myimage.jpg';

And it doesn’t work. Note that I just hardcoded “54237″ for testing…

Any suggestions ???

Thanks again!

You could use getChildAt() or getChildByName() to access the dynamically created component instances. Something like the following:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white"
        creationComplete="init();">

    <mx:Script>
        <![CDATA[
            import flash.utils.getDefinitionByName;
            import mx.controls.Button;

            private const dummyArr:Array = [Button];

            private function init():void {
                var c:Class = getDefinitionByName("mx.controls.Button") as Class;
                var idx:uint;
                var len:uint = 5;
                for (idx = 0; idx < len; idx++) {
                    var obj:Button = new c();
                    obj.label = "Button " + idx;
                    obj.name = "button" + idx;
                    addChild(obj);
                }
            }

            private function btn_click(evt:MouseEvent):void {
                var b:Button = getChildByName("button3") as Button;
                b.label = "OUCH";
            }
        ]]>
    </mx:Script>

    <mx:ApplicationControlBar dock="true">
        <mx:Button id="btn"
                label="Change Button 3"
                click="btn_click(event);" />
    </mx:ApplicationControlBar>

</mx:Application>

Let’s say you created 10 components. And then you want to reference those components in actionscript. How would you do so?

For example, let’s say you wanted to dynamically change the background of one of the components. How you you write the actionscript (instance.backgrouColor = #000000 ??? )
