[Dojo-interest] Expand my tree on clicking a button

[Veyrenche Rémi]

Hello,


i want to expand my tree when i'm clicking a button "expand" :
 my javascript function who don't work :
function expand()

    {
        var myController = dojo.widget.getWidgetById("Tree");
        myController.expand(node);

    }

My button :

<button dojoType="Button"  onclick="expand()">
    Expand
    </button>


My tree :
 <div dojoType="TreeSelector"
     widgetId="treeSelector"
     eventNames="select:nodeSelected;dblselect:nodeDblSelected">
</div>
    <div dojoType="Tree" toggle="fade" toggleDuration="500"
selector="treeSelector">
          <div dojoType="TreeNode" title="name" object="mypage.php" ... >
                                   <div dojoType="TreeNode" title="name"
object="mypage.php" ... >
                                   </div>
          </div>
      </div>



I think it's exist a simple way to use the expand function, but i'm a
beginners in javascript;

Thanxs to you.
Cheers.
