RE: [flexcoders] help moving elements in a tree

[Deepa Subramaniam]

Tree formats its drag and drop items as “treeItems” instead of “items” which is what the other list-based controls use. So try:   private function doDragDrop(event:DragEvent):void {                    var dropTarget:Tree=Tree(event.currentTarget);                        doDragExit(event);             var items:Array =event.dragSource.dataForFormat("treeItems") as Array;             Alert.show(items.length.toString());         }    From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jesús Iglesias Sent: Monday, November 06, 2006 3:08 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] help moving elements in a tree   Hi,   I have a tree where I can move elements from one node to another. I have enabled drag and drop and all works fine. The last step is I need to know some details about destination. I created a doDrgagDrop function as on doc,    dragEnabled="true"  dropEnabled="true"  dragMoveEnabled="true"  dragEnter="doDragEnter(event);"  dragExit="doDragExit(event);"  dragOver="doDragOver(event);"  dragDrop="doDragDrop(event);" where:           private function doDragDrop(event:DragEvent):void {                    var dropTarget:Tree=Tree(event.currentTarget);                        doDragExit(event);             var items:Array =event.dragSource.dataForFormat("items") as Array;             Alert.show(items.length.toString());         }    But I get an error accesing a null object.   I supose after moving the element I could find the parent node in order to update database which this movement, but I need to know son info about moved element.   Please help!!   Thanks, Jesus   __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Software development tool Software development Software development services Home design software Software development company Your email settings: Individual Email|Traditional Change settings via the Web (Yahoo!
