I would use a custom renderer.

Re: [flexcoders] Re: Folder-style dragOver highlight on tree
Could you elaborate a bit, please? The component is already used with a custom renderer. Are you suggesting that the dragEnter method should just do the highlighting directly? Makes sense, I suppose.

Re: [flexcoders] Re: Folder-style dragOver highlight on tree
Doesn't the node already highlight because you are rolling over it?
Re: [flexcoders] Re: Folder-style dragOver highlight on tree
No, this is dragging items from a datagrid to a tree. On Wed, May 12, 2010 at 10:43 AM, Baz li...@thinkloop.com wrote: Doesn't the node already highlight because you are rolling over it?
Re: [flexcoders] Re: Folder-style dragOver highlight on tree
Though I strive to avoid subclassing the standard components, the code I
inherited already has a Tree subclass, so I added the following:
public function highlightItem(item:IListItemRenderer,
highlighted:Boolean):void {
this.drawItem(item, false, highlighted);
}
And call it from the renderer's dragEnter handler:
MyTreeSubclass(this.listData.owner).highlightItem(this, true);
Seems to be working OK.

Re: [flexcoders] Re: Folder-style dragOver highlight on tree
And of course I had to add to my renderers dragExit:
MyTreeSubclass(this.listData.
owner).highlightItem(this,false );
