Hi,
check the two solutions which ever you feel is best you can use that [
expanding and collapsing treeview].
<mx:LinkButton toolTip="Expand All" id="LBTreeExpand" x="0" y="0"
icon="@Embed(source='../../images/arrow-down.gif')" height="18" paddingLeft="0"
paddingRight="0" paddingTop="0" paddingBottom="0" click="ExpandTree();"/>
private function ExpandTree():void
{
if(LBTreeExpand.toolTip.toString() == "Expand All")
{
LBTreeExpand.setStyle("icon", CollapseIcon);
LBTreeExpand.toolTip = "Collapse All";
for(var i:int=0; i<TreeData.length.valueOf(); i++)
{
listTree.expandChildrenOf(TreeData.getItemAt(i), true);
}
}
else if(LBTreeExpand.toolTip.toString() == "Collapse All")
{
LBTreeExpand.setStyle("icon", ExpandIcon);
LBTreeExpand.toolTip = "Expand All";
for(var i:int=0; i<TreeData.length.valueOf(); i++)
{
listTree.expandChildrenOf(TreeData.getItemAt(i), false);
}
}
}
----------------------------
simple approach
private function ExpandTree():void
{
myTree.expandChildrenOf(treeData.getItemAt(0), true);
}
private function CollapseTree():void
{
myTree.expandChildrenOf(treeData.getItemAt(0), false);
}
