Re: [Laszlo-dev] JS2 and LZX syntax / instantiation

[P T Withington]

Not sure exactly what you are asking here, but we don't support  
mixin's at the LZX level yet, so there is no way to do exactly what  
you are doing in "pure" LZX.

Hi all,

Here's a simple JS2 class I wrote for testing. What would be the  
exact LZX
representation be? I'm trying do better understand instantiation of  
LZX
based classes and JS2 based classes. Either I made a mistake or I  
see some
differences for classes I port from LZX to JS2 syntax.

<library>

 <!-- testclassjs2, want to see how JS2 compares to LZX.

 <interface name="testclassjs2" extends="node">

   <!--- A test attribute.

         @access private
   -->
   <attribute name="src" value="" type="string"/>

 </interface>

 <!-- these methods are shared across runtimes -->

attrs:Object?
