RE: [flexcoders] Fw: [BETA3] I found how can remove the selected item of mx.controls.Tree.

[Tracy Spratt]

Bryan, I found another way to do this, using XMLListCollection.  Strangely, I still have to call invalidateList to get the tree to refresh.  My understanding was that the XMLListCollection methods would handle the needed events, but apparently not.   Tracy               //deletes the currently selected node             private function deleteSelectedNode():void             {                         var nodeToDelete:XML = XML(treeData.selectedItem);    //reference to the node to delete                         var xlcParent:XMLListCollection = new XMLListCollection(nodeToDelete.parent().children()); //collection of nodes containing the node to delete                         var iIndex:int = xlcParent.getItemIndex(nodeToDelete);    //index of node to delete in collection                         xlcParent.removeItemAt(iIndex);    //remove the node                         treeData.invalidateList();    //refresh the tree             }//deleteSelectedNode   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Bryan Choi Sent: Wednesday, May 24, 2006 4:22 AM To: flexcoders Subject: [flexcoders] Fw: [BETA3] I found how can remove the selected item of mx.controls.Tree.     ----- Original Message ----- From: Bryan Choi To: flexcoders Sent: Tuesday, May 23, 2006 9:33 PM Subject: [BETA3] I found how can remove the selected item of mx.controls.Tree.   Hi, all.   var treeItem :Object = mxTree.selectedItem;   var parentItem :Object = mxTree.getParentItem ( treeItem );   var items :ICollectionView = treeDD.getChildren (parentItem);   var len :int = items.length;   for ( var i:int=0; i<len; i++ )   {    if ( items [EMAIL PROTECTED] == [EMAIL PROTECTED] )    {     treeDD.removeChildAt ( parentItem, mxTree.selectedItem, i );     break;    }   }   ===========================   It is lengthy. so..   I want Anyone who has idea other to know simple code rather than above.   Thank you, Brayn. -- 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 Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
