[Laszlo-dev] createChildren

 > I think the documentation on makeChild is more accurate.

Unfortunately makeChild is marked as private and thus is not part of the 
documentation.

where and when it actually makes its children.

I have done a splitpane that automatically creates a divider for each 
pane. Fairly normal and straightforward use case. So I think 
createChildren is a very powerful place for overrides and strongly 
suggest it is kept as part of the official api.

 > c.name is still valid, it is used to make a child be of the class 
that implements a particular tag

I don't think so.

Code: (slightly modified from previous mail):
-----
<canvas debug="true">
     <view >
         <method name="createChildren" args="children"><![CDATA[
             for(var i=0; i<children.length; i++) {
                 Debug.inspect(children[i]);
             }
         ]]></method>
         <view height="${canvas.height}"/>
         <view/>
     </view>
</canvas>

Output:
-------
«Object#0» {
   attrs: {…, height: $always{canvas.height}}
   class: <anonymous view>
}
«Object#4» {
   attrs: {…}
   class: <view>
}

 > 2) Instantiate 'instance classes'

Is there any other way for me (or the compiler) to recognize 
tags/classes from each other? Because if not then the word 
"optimization" is incorrect.

What do you mean with "non-debug" version?
It is clear to me that if there is no debug window then I will not see 
the debug messages :-)

So can I now rely on the tagname of my Pane tag to be either "Pane" or 
"anonymous Pane" ?

 > Before, we never emitted a tagname for "instance classes".

So was the
- child['class'].tagname
previously in my example case "undefined" or "Pane" (It must have been 
"Pane" because otherwise my SplitPane would not have worked previously.)
