hi all
I just need a quick help with how to pick up if a tree is expanded or
not. I've almost got it - it'll expand all but not collapse.
I don't think "myTree.openItems != null" is correct but I can't think
of what else....
private function toggleExpandCollapseTree():void
{
myTree.selectedIndex = 0;
if (myTree.openItems != null){
myTree.expandChildrenOf(myTree.selectedItem , true);
btnExpandCollapseTree.label = "Collapse All";
}else{
myTree.expandChildrenOf(myTree.selectedItem , false);
btnExpandCollapseTree.label = "Expand All";
}
}
any suggestions? thanx.
PS: I have to cater for cases where only a root node exists
