[Dynapi-Dev] Problems in inheritence (General and PanelBar)

[Peter R. <ant...@gm...>]

Hi,

I have two problems here. First I cannot subclass PanelBar until I 
comment out some stuff in the constructor like that:

function PanelBar(lyrmnu,lyrcnt,mnuheight,x,y,w,h,mnucss,cntcss,minimized) {

   this.DynLayer = DynLayer;
   this.DynLayer(null,x,y,w,h,null);

   if (lyrmnu) {	
     this.x = x;
     ...
     this.menu.setHTML(this._mnuhtml.replace('{@min}',this._mnuhtmlmax));
   }
		
   this.onPreCreate(PanelBar.PreCreateEvent);
   this.onCreate(PanelBar.CreateEvent);
}
}

Is there any common pattern how to avoid problems with subclassing? Or 
am I doing something totally stupid in trying to subclass PanelBar?

The next problem is that I can't enable the dragevents on my subclass of 
PanelBar until I change dragevent.js line 225 (enableDragEvents):

if(lyr.isClass('DynLayer')) lyr.addEventListener(DragEvent.lyrListener);

to

lyr.addEventListener(DragEvent.lyrListener);

That is bruteforce, I know ;) I just tried to figure out where the 
problem is. And I found that myPanelBarSubclass.isClass('DynLayer') 
yields false which I consider as wrong - it is a DynLayer since it is a 
subclass of PanelBar which is a subclass of DynLayer! The quickest fix I 
can imagine is to rewrite the isClass-method to tell whether any 
superclass matches the argument. I don't know if this breaks something, 
so I didn't try that yet.

If I am trying to do something totally wrong then please tell me! 
Otherwise I will gladly help "fixing" the issues.

Regards,
Peter
