I don't know if this helps but following is an example of passing properties to the XMLConnector component using attachMovie.  The idea is the same for any Class.  Setting the Classes properties in o:Object and then passing it thru attachMovie will set the properties within the new Class instance.  Hope this helps:
 
var o:Object = new Object();
   
o.direction = "send/receive";
o.params = new XML(str);
o.URL = "";
   
var new_object = this.attachMovie("XMLConnector","xml_object",next_depth,o);
next_depth++;

Depth was another problem I had,
When I use attachMovie in the Menu Class I have to specify a depth
But I also have to specify a depth when using attachMovie within the TabButton Class.
(I thought all the depths are relative to the root timeline, Therefore I needed to pass through a depth param as this class is called dynamically);

I couldn’t find a way to do pass a depth param to the TabButton constructor.
So instead I didn’t use attachMovie in the MovieClip constructor but ratherin a function I create setProps() where I pass through the depth as a param and then use attachMovie in that function.

This is where I think I’ve made a mistake.
This is the first time I have really used inheritance on the MovieClip Class.

If Menu class doesn't extend MovieClip then I would have thought it wouldn't have access to attachMovie which is a method of MovieClip.  But you say it worked for a single instance.  If you don't have access to attachMovie I wouldn't have expected it to work at all.

 

How come you increment _depth twice when you have only used one depth?  It shouldn't affect the outcome but I'm just curious.

I’m having some trouble applying these new (to me) best practices I watched the other night.

I am trying to build a dynamic menu;

 

I have a Main.as class that extends movieClip that calls a menu class

new HorizontalTabMenu(model.getMenuArray(), this, 200, 20, 20);

 

The menu class doesn’t extend movieClip and its purpose is to manage the menu and attach the buttons.

 

The button movieClip has a class attached; “TabButton” is the mc, with “TabButton.as” attached

 

So I’m trying to attach the clips from the menu class but it isn’t working

(BTW I had it working on a single instances, it’s this example where I’m creating multiple instances is where I’m making a mistake)

 

Menu class ~

for (var i:Number = 0; i<mData.length; i++)

{

               tab = target_mc.attachMovie("TabButton", "tab"+i+"_mc", _depth);

               _depth++;

               tab.setProps(this, mData[i].LABEL, mData[i].ID, _depth);

               _depth++;

               tab._x = _x;

               tab._y = _y;

               _x += tab.returnNextX();

               tabs_array.push(tab)

}

 

^ here im trying to attach the mc from the library into the tab var so that I can add it to the array

^ without doing that I wasn’t sure how I could reference the movieclip without placing it in the mc_variable

 

I have a trace running on the TabButton class constructor and it doesn’t instantiate.
