Hello, I'm trying to do an application where the user can select images and put in on a panel (similar the example Diagrammer in the tour of Flex). Could you send me some example?

But I'm having all sorts of problems. The tree's dataprovider is XML. I'm only interested in selecting the child nodes (@label == "Receipt").. ..that means I have to expand the menu as well. Can someone give me some ideas? Code -> <mx:Application xmlns:mx="http://www.adobe. com/2006/ mxml"> <mx:Button label="test" click="test( )"/> <mx:Tree id="menuTree" labelField=" @label" width="40%" height="90%" showRoot="false" dataProvider= "{menu_data} "/> <mx:Script> <![CDATA[ public function test():void { //this is failing miserably- doesn't expandItem and adds // some other rubbish to the tree menuTree.selectedIt em = XML(menuTree. dataProvider[ 0]).node. node.(@label == "Receipt"); } ]]> </mx:Script> <mx:XML id="menu_data" xmlns=""> <MenuOne> <node label="Receiving" > <node title="Purchase Order" label="Purchase Order" /> <node title="Receipt" label="Receipt" /> </node> <node label="Inventory" > <node title="Stock SKU" label="Stock SKU" /> <node title="Stock Slot" label="Stock Slot" /> </node> </MenuOne> </mx:XML> </mx:Application>
