Hi Douglas,
It is carrying the leaf nodes properly; I think the issue revolved around
how you were trying to display the items.
public function handleMe(event:DragEvent) : void {
var ds:Array = event.dragSource.dataForFormat("treeItems") as
Array;
for( var i:int = 0; i < ds.length; i++ ){
trace(XML(ds[i]).toXMLString());
}
}
Hope this helps,
Michael

Subject: [flexcoders] Re: Tree, drag+drop, and XML
here is example code of what I am seeing. Why doesn't a leaf carry the data
in the drag event?
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx=" <http://www.adobe.com/2006/mxml>
http://www.adobe.com/2006/mxml"; layout="vertical">
<mx:Script>
<![CDATA[
import mx.events.DragEvent;
import mx.controls.Alert;
import mx.core.DragSource;
import mx.utils.ObjectUtil;
public function handleMe( event:DragEvent) : void {
var ds:Array = event.dragSource.dataForFormat("treeItems")
as Array;
Alert.show(ObjectUtil.toString(ds));
}
]]>
</mx:Script>
<mx:XML id="treeData">
<node label="Mail Box">

</mx:XML>
<mx:Tree id="myTree"
labelField="@label"
showRoot="false"
itemRenderer="renderer.ActivityTaskTree"
dataProvider="{treeData}"
dragEnabled="true" />
<mx:TextArea text="drop enter here" dragEnter="handleMe( event )">
</mx:TextArea>
</mx:Application>

I have a Tree, and a dream it seems. The Tree's dataProvider is XML based.
The Tree looks lovely and bares leaves. I set dragEnabled = true. On
another object in my app I am capturing the dragEnter event with this mehtod
private function doDragEnter(event : DragEvent) : void {
var ds:Array = event.dragSource.dataForFormat("treeItems") as
Array;
Alert.show (ObjectUtil.toString(ds));return;
}
Now, if I drag a leaf over this object, the Alert above displays
(Array)#0
[0]
as in it does NOT display the XML frag represented by the leaf.
If I drag a branch, item with the folder icon, the Alert above displays
(Array)#0
[0]<node label=.......</node>
it displays the XML frag for the branch and all its children?
WT?
