I have a tree control and I want to give the user the ability that he can move up and down the element he just selected with a up and a downbutton. The tree gets generated from XML.
I managed to insert the selected item a second time at a other place, with the following code:
var parentXML:XML = XML(containerTree.selectedItem).parent();
var upperItem:XML = topContainer.source[containerTree.selectedIndex-1];
parentXML.insertChildBefore(upperItem,XML(containerTree.selectedItem));
but then I have the item there twice in the List. How can I remove to reinsert it?
Thanks for Hints! Markus
Use the
delete (XML)
operator to remove XML nodes .
var parentXML:XML = XML(containerTree.selectedItem).parent();
var upperItem:XML = topContainer.source[containerTree.selectedIndex-1];
delete containerTree.selectedItem;
parentXML.insertChildBefore(upperItem,XML(containerTree.selectedItem));
