Time format -- Flex 2.01

You use the Time format for component properties that move or have built-in effects, such as the ComboBox component when it drops down and pops up. The Time format is of type Number and is represented in milliseconds. Do not specify the units when entering a value in the Time format.

The following example sets the selectionDuration style property of the myTree control to 100 milliseconds:

<?xml version="1.0"?>
<!-- styles/SetStyleExample.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="initApp()">
  
  <mx:Script><![CDATA[
     public function initApp():void {
        myTree.setStyle("selectionDuration", 100);
     }
  ]]></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="Spam"/>
        <node label="Sent"/>
     </node>    
  </mx:XMLList>

  <mx:Panel title="Tree Control Example" width="100%">
        <mx:Tree id="myTree" width="100%" labelField="@label" dataProvider="{treeData}"/>
