[flexcoders] Flex2B3 - Drag And Drop - Drop Into Tree (different from B2)

Thu, 11 May 2006 03:55:16 -0700

Hi All

I'm having difficulty with the drop part of the drag and drop in a Tree
in B3.

I  have my tree defined this way:
<mx:Tree id="myTree"
        dataProvider="{myTreeData}"      
        dragEnter="doDragEnterTree(event);"
        dragDrop="doDragDropTree(event);"/>

And I have this method for dragDrop:

private function doDragDropTree(event:DragEvent):void {      
    trace("DROP IN TREE index:" + myTree.calculateDropIndex(event));
}

This works well. My problem is: I want to know WHERE exacty the drop was
fired (where did the user released the mouse button) to know where the
insert my new item. The calculateDropIndex works well for List type
components, but for a Tree it is useless. It returns a level number.

In B2 the Tree had a method Tree.getDropParent(event), I suppose this
returned what I was looking for, but in B3 the Tree has no such a
method. In "Flex Beta 2 to Beta 3 Changes" it says:

Tree.getDropParent(event) - Use Tree.getParentItem(item:Object):*.

But I don't understand the logic here. getParentItem() has as parameter
item:Object, and I don't kno that, I know just an event, I want to find
out the item:Object.

What is the solution here?

Thanks for your help!

Andi
