[Laszlo-dev] JS2 and LZX syntax / instantiation

[Raju Bitter]

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

  </interface>

  <!-- these methods are shared across runtimes -->
  <script when="immediate"><![CDATA[
    mixin Testclassjs2Shared {
        function Testclassjs2Shared ( parent:LzView? = null , attrs:Object?
= null , children:Array? = null, instcall:Boolean  = false) {
            super(parent, attrs, children, instcall);
        }
    }
  ]]></script>

  <script when="immediate"><![CDATA[

    // Classes that implement an interface must obey the LZX
    // tag->class mapping convention
    dynamic class $lzc$class_testclassjs2 extends LzView with
Testclassjs2Shared {

        // Next two are part of the required LFC tag class protocol
        static var tagname = 'testclassjs2';
        static var attributes = new LzInheritedHash(LzView.attributes);
        static var uid = 0;
        
        var src = "";
        
        var onsrc = LzDeclaredEvent;

        override function construct(parent,args) {
            super.construct(parent, args);
            Debug.write("constructor");
            new LzDelegate( this , "_oninit" , this , "oninit" );
            new LzDelegate( this, "_onSrc", this, "onsrc");
        }

        function $lzc$class_testclassjs2(parent, attrs, children, async) {
            super(parent, attrs, children, async);
        }

        override function init() {
            super.init();
            Debug.write(this, "init()");
        }
        
        function _oninit(ignore) {
            Debug.write(this, "_oninit()");
        }
         
        function _setSrc(value) {
            Debug.write(this, "_setSrc()", value);
            this.src = value;
        }
        
        function $lzc$set_src(value) {
            Debug.write(this, "$lzc$set_src()", value);
            this._setSrc(value);
            this.onsrc.sendEvent(this);
        }

        function _onSrc (evt) {
            Debug.write(this, "_onSrc()", evt);
        }
        

    } // End of testclassjs2
    lz[$lzc$class_testclassjs2.tagname] = $lzc$class_testclassjs2;
  ]]></script>
</library>

Thanks,
