Component

If you like being on the cutting edge you should get the source of my control

at codeplex the source is using Ext 1.0 alpha3 rev 4 and has the first version of the TreePane control.Everything is working nice..the only thing missing to an official release is Grid Drag and drop row sorting.

The differences between yui-ext 0.33 and Ext 1.0 are wrapped inside the control , so no changes are needed in the samples ( unless you want to get some new features). Thats one of the advantages of using the control...

Ext 1.0 to be released on monday

I just read on yui-ext forum that Ext 1.0 its scheduled to be released on monday (19). As many of you probably know I am Brazilian and in Brazil next week is "Carnaval" and that means I will start working on that week on the 22.So expect me to release the new yui-ext controls extender only in march.

I do hate "Samba", but I love the long holiday....

How do I persist a TreePanel?

Ext its not out yet but here is the code:

YAHOO.ext.tree.TreePanel.prototype.toJsonString=function(){
var nodes=this.getRootNode().childNodes;
this.arrNodes=[{id:this.getRootNode().id,parent:0}];
  for(var i=0;i< nodes.length;i++){
       this.arrNodes.push({id:nodes[i].id,parent:this.getRootNode().id});
       this.processChildren(nodes[i]);
  }
  return YAHOO.ext.util.JSON.encode(this.arrNodes);
}
/*
    Recursive function 
    sweeps the tree in all levels
*/
YAHOO.ext.tree.TreePanel.prototype.processChildren=function(node){
   child=node.childNodes;
   for(var i=0;i<child.length;i++){
       this.arrNodes.push({id:child[i].id,parent:node.id});
       this.processChildren(child[i]);
   }
}

It returns a jsonString with an array of objects with the tree nodes and its parents reflecting the changed tree. When Ext comes out I will build a complete sample persisting that output to a database.
