Re: Re: SV: [Dynapi-Dev] Widget constructor

[Barre B. <ba...@ho...>]

hmm seems kindof obscure..
It strikes me as having a construct method to be a cleaner 
way of doing initialization.. almost like calling super() 
in Java... hm?
(The code below should work)

function DynLayer() { this.construct(arguments) }
DynLayer.prototype.construct=function(){
	var a=arguments[0]
........etc.......

function widget(){
   this.construct(arguments)
}
widget.prototype=new DynLayer

Re: Re: SV: [Dynapi-Dev] Widget constructor

[Scott A. L. <sc...@sc...>]

I have to agree that Brandon's SuperClass object is great.  It automatically
manages things like class instances and super methods, so you don't have to
worry about overwriting anything.  It's very slick, and little more like
"real" OOP.  I think we need an updated version released, though.

but how would you want to handle widget-specific initialisation?
