RE: [flexcoders] Expand all items of a tree

It’s working for me. Here’s an example. I’m not sure what you are wanting to do, but in this example you have to select a tree item, then click the Expand All button. You can modify it as desired.

 

<?xml version="1.0" encoding="utf-8"?>

<!-- Tree control example. -->

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

 

    <mx:Script>

        <![CDATA[

 

            [Bindable]

            public var selectedNode:Object;

 

            // Event handler for the Tree control change event.

            public function treeChanged(event:Event):void {

                selectedNode=Tree(event.target).selectedItem;

            }

           

            private function expand():void

            {

                        myTree.expandChildrenOf(myTree.selectedItem, true);

            }

        ]]>

    </mx:Script>

 

    <mx:XMLList id="treeData">

        <node label="Mail Box">

            <node label="Inbox">

                <node label="Marketing"/>

                <node label="Product Management"/>

                <node label="Personal"/>

            </node>

            <node label="Outbox">

                <node label="Professional"/>

                <node label="Personal"/>

            </node>

            <node label="Spam"/>

            <node label="Sent"/>

        </node>   

    </mx:XMLList>

            <mx:Tree id="myTree" width="427" height="410" labelField="@label"

                showRoot="false" dataProvider="{treeData}" change="treeChanged(event)"/>

 

    <mx:Button label="Expand all" click="expand()"/>

</mx:Application>

Subject: [flexcoders] Expand all items of a tree

 

Hi, in flex2b3, I could open all nodes of my tree by doing this:

 

treeTest.selectedIndex = 0;

treeTest.expandChildrenOf(treeTest.selectedItem, true);   

 

Unfortunately, this isn’t working anymore.

 

I tried treeTest.expandItem(treeData.node[0],true, false); , teeTest.expandChildrenOf(treeTest.firstVisibleItem), but no luck.

 

Who helps?

 

Jonas
