Header renderer code

The following example shows the source code for the header renderer class, which is in a file named myRenderer.as. The bold text indicates where the tooltip for the first column header is created in the createChildren() method.

import mx.controls.Label;
class myRenderer extends mx.controls.Label{
   var lbl : MovieClip;
   var listOwner : MovieClip; //Reference to the parent DataGrid.

   function myRenderer(){
   }
   public function createChildren():Void {
      lbl = createClassObject(Label, 'label', 1, {toolTip: 'User names here.'});
      lbl.text = "Name";
   }

   public function getPreferredHeight():Number {
      return listOwner.rowHeight;
   }

   public function layoutChildren():Void {
      lbl.setSize(80, listOwner.rowHeight);
   }

   function setValue(str:String, item:Object, sel:Boolean) : Void {
   }
}
