<!-- as/MainHBoxWithAlert.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" 
    xmlns:MyComp="myComponents.*">

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

            public function addButton():void {
                var myButton:Button = new Button();
                myButton.label = "New Button";
                myHBox.addChild(myButton);
            }
        ]]>
    </mx:Script>

    <MyComp:HBoxWithAlert id="myHBox">
    </MyComp:HBoxWithAlert>

    <mx:Button label="Add Button" click="addButton();"/>
