First thanks for responding,
I assume this is a flex 1.5 example as no dragevent is in the call to
dropparent etc..
I'm using flex 2.0 alpha, and this is the code for the drop event.
The below code should work but does not. The item dropped is always
inserted at the bottom or the parent. In the underlying data source
the dropped node is in the correct location. This only happens when
using a xml, or e4x result for binding to the tree component. I need
to get this working for e4x results. So; it seems that the data
source is updated correctly but the tree control does not reflect the
changes.
Does this make sense ?
private function handleDragDrop(event:DragEvent)
{
event.target.hideDropFeedback(event);
var items:Object = event.dragSource.dataForFormat("treeItems");
var dropLoc:int = event.currentTarget.getDropLocation(event)
var dropparent:Object = event.currentTarget.getDropParent(event);
for each (var item:Object in items){
dropparent.addTreeNodeAt(dropLoc,item);
}
}
Thanks again for your help.
