Question

I have a BaseComponentClass that I am using as the class that all my custom components extend.
For some reason, none of my custom components show up at runtime. I am not getting any compile or runtime errors either.
I am implementing all the protected UIComponent methods.
My code looks like this:

public class BaseComponentClass extends UIComponent
{
    public function BaseComponentClass()
    {
        super();
    }

    override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void 
    {
            super.updateDisplayList(unscaledWidth, unscaledHeight);
    }       

    override protected function createChildren():void 
    {
        super.createChildren();

        for (var i:uint=0; i < super.numChildren; i++)
        {
            var childObj:DisplayObject = super.getChildAt(i);
            addChild(childObj);
        }           
    }

    override protected function commitProperties():void 
    {
        super.commitProperties();
    }

    override protected function measure():void 
    {
        super.measure();
    }
}

Then I use it as the Base class in my mxml custom components somewhat like this:

<local:BaseComponentClass xmlns:local="local.com.*" xmlns:mx="http://www.adobe.com/2006/mxml">
     <mx:Button id="btn" label="My Button" />
</local:BaseComponentClass>

The Button never shows up at runtime.

Answer 1

Apparently you want to add child objects to your BaseComponent.

Why don’t you inherit from a class that supports this functionality, such as Box or Canvas?
