I have got a AS3 Dock Menu script from [http://www.reloc.org/2008/2/23/os-x-dock-in-as3-and-flex](http://www.reloc.org/2008/2/23/os-x-dock-in-as3-and-flex)

And I am trying to get it to Load content in to a Movie Clip when an icon is pressed but I am having some serious trouble doing it. I had it sugested to me that I try using cases so I did but then I needed to create a Variable in the .AS file(below) but I am totally lost.

Would some one tell me what I am doing wrong or what I could do to get it working.  
My movie Clip that I want to load images in to in the .Fla is called “ldr”.

original code:

```auto
package
{
    import flash.display.MovieClip;
    import org.reloc.dock.*;
    
    public class DocumentClass extends MovieClip
    {
        private var items = [
                    { icon: new finder(128, 128), id: 'finder' },
                    { icon: new safari(128, 128), id: 'safari' },
                    { icon: new mail(128, 128), id: 'mail' },
                    { icon: new itunes(128, 128), id: 'itunes' },
                    { icon: new ichat(128, 128), id: 'ichat' },
                    { icon: new search(128, 128), id: 'search' },
                    { icon: new help(128, 128), id: 'help' },
                    { icon: new trash(128, 128), id: 'trash' }
                    ];

        public function DocumentClass()
        {
            stage.scaleMode = 'noScale';

            var dock:Dock = new Dock('bottom', 128, 32, 128, 2, 0, 0, items);
            dock.x = stage.stageWidth / 2;
            dock.y = stage.stageHeight;
            addChild(dock);
            
            addEventListener(DockEvent.CLICK, onClick);
        }
        
        private function onClick(event:DockEvent):void
        {
            var icon:DockIcon = event.target as DockIcon;
            trace(icon.info.id)
        }
    }
}

```

My changes

```auto

package
{
    import flash.display.MovieClip;
    import org.reloc.dock.*;
    
    public class DocumentClass extends MovieClip
    {
        private var items = [
                    { icon: new finder(128, 128), id: 'finder' },
                    { icon: new safari(128, 128), id: 'safari' },
                    { icon: new mail(128, 128), id: 'mail' },
                    { icon: new itunes(128, 128), id: 'itunes' },
                    { icon: new ichat(128, 128), id: 'ichat' },
                    { icon: new search(128, 128), id: 'search' },
                    { icon: new help(128, 128), id: 'help' },
                    { icon: new trash(128, 128), id: 'trash' }
                    ];

        public function DocumentClass()
        {
            stage.scaleMode = 'noScale';

            var dock:Dock = new Dock('bottom', 128, 32, 128, 2, 0, 0, items);
            dock.x = stage.stageWidth / 2;
            dock.y = stage.stageHeight;
            addChild(dock);
            
            addEventListener(DockEvent.CLICK, onClick);
        }
        
        private function onClick(event:DockEvent):void
        {
            var icon:DockIcon = event.target as DockIcon;
            var ldr:MovieClip
            //trace(icon.info.id)
            switch(this.DockIcon) {
                case 'finder':
                this.ldr.source = "clip1.swf";
                Break;
            }
        }
    }
}

```

try this

package  
{  
import flash.display.MovieClip;  
import flash.net.URLRequest;  
import org.reloc.dock.\*;  
import flash.display.Loader;

    			{ icon: new finder(128, 128), id: 'finder' },

    			];

	public function DocumentClass()
	{
	    stage.scaleMode = 'noScale';

		var dock:Dock = new Dock('bottom', 128, 32, 128, 2, 0, 0, items);
        dock.x = stage.stageWidth / 2;
        dock.y = stage.stageHeight;
		addChild(dock);
		ldr = new Loader();
		this.addChildAt(ldr,0);
		addEventListener(DockEvent.CLICK, onClick);
	}
	
	private function onClick(event:DockEvent):void
	{
	    var icon:DockIcon = event.target as DockIcon;
		switch(icon.info.id) {
            case 'finder':
			ldr.load(new URLRequest("clip1.swf"));
            break;
        }

	}
}

```

}

The mistake you had done  
1.

> switch(this.DockIcon) {

here you cant add switch element to a class Name insted use an instance or any function of the class  
which returns some value.

1. 

> Break;

it is break; not Break;

1. 

> var ldr:MovieClip  
> //trace(icon.info.id)  
> switch(this.DockIcon) {  
> case ‘finder’:  
> this.ldr.source = “clip1.swf”;  
> Break;  
> }

you have declared a movieClip name ldr which is not the child of this(here it is the root).  
Try loader class.to load the swf and add it to the root at your desired depth.
