This is interresting .. i have to understand the core mechanism of OL :)
so i have few questions again :
1) Do you know where are theses core JS library (ex LzView) in the LPS
server ? i didn't find them under /lps tree.
1bis) =>And who is doing the binding from LZX code to ECMA code ? i
guess it's the OL compiler / servlet couple ?
2) Which object framework is used by OL ? prototype.js ?
another question about HCI design:
-3) Is it possible to have a MVC mechanism in OL ? I was thinking about
declaring static my component in a sort of view, bind them in a JS
library playing the role of the Controler, and then a model.
an example with a button that init and connect to a rtmp server (it's a
draft)
-------------------------------------------------------------------------
<!-- the "view" myapp.lzx-->
<canvas>
<edittext id="edittextServerAddress" />
<button id="mybutton" >connect</button>
<script src="mycontroler.js">
...
<canvas/>
-------------------------------------------------------------------------
<!-- the "controler" mycontroler.js -->
//creating the model, ideally, the view would be created here too, but
the view is the app entry point so i guess it have to be created first
and then the view have to create the controller
var rtmpconn = new myrtmpconnection();
// binding view to controler
mybutton.onclick = function(button)
{
button.setAttribute('text','connecting ...');
rtmpconn.setAttribute ... etc
rtmpconn.myModelInitMethod(edittextServerAddress.text);
rtmpconn.connect();
}
// "controller classic" functions callable from "external"
function init(adress){
... code ...
rtmpconn.myModelInitMethod(adress);
... code ...
}
-------------------------------------------------------------------------
<!-- the model "mymodel.lzx" -->
<library>
<class name="myrtmpconnection" extends="rtmpconnection">
<attribute name="myModelVar" />
<method name="myModelInitMethod" args="adress"=> (code) </method>
</class>
</library>
... hope that is clear ... the idea is to have a "real" agent MVC model
... but that's maybe a bad/wrong way ?
thanks a lot

Henry Minsky a écrit :
I should add that there is a certain magic translation of core class
names
from LZX to Javascript that is happening, so <view> actually
corresponds to
the real class named LzView, same for most of the core classes that are
user visible. The magic happens via the static var declaration in a
class called "tagname":
class LzView extends LzNode {
static var tagname = 'view';
..
As Tucker said, if you redefine a core class like that, you do so at
your own risk,
all sorts of things will probably break.

Welcome to dynamic languages. Yes, it is allowed. If you really
wanted to, you could replace the core classes too. And, yes, it will
probably cause a problem if you do.
In general, Javascript emphasizes flexibility over safety. IMO, Java
leans the other way.
