Well, if some one want create ComboBox by Constructor. Please use:

var combo:ComboBox = new ComboBox();
combo.x = 3;
combo.y = 40;
combo.width = 138;
combo.itemRenderer = new ClassFactory(mx.controls.Label);
……..

best,

Peter,
I wonder how mx.controls.TextInput control would be used as an item renderer for mx.controls.ComboBox control.

Chandra Kumar, Try something like the following instead:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="top"
        backgroundColor="white">

    <mx:Array id="arr">
        <mx:Object label="Lorem ipsum dolor sit amet, consectetuer adipiscing elit." />
        <mx:Object label="Donec sit amet dui nec pede aliquam auctor." />
        <mx:Object label="Integer vestibulum sodales dui." />
        <mx:Object label="Sed nonummy ligula et tortor." />
        <mx:Object label="Aenean varius neque vel felis." />
        <mx:Object label="Phasellus venenatis ipsum sit amet nisi." />
        <mx:Object label="Nullam vitae turpis et ipsum cursus venenatis." />
        <mx:Object label="Pellentesque tincidunt pede non arcu." />
        <mx:Object label="Aliquam ut massa quis ante dignissim egestas." />
        <mx:Object label="Curabitur facilisis velit sit amet metus." />
        <mx:Object label="Vivamus ornare massa ac massa." />
        <mx:Object label="Nam accumsan rutrum purus." />
    </mx:Array>

    <mx:ComboBox id="cb"
            dataProvider="{arr}"
            width="250"
            open="cb.dropdown.variableRowHeight = true;">
        <mx:itemRenderer>
            <mx:Component>
                <mx:Text selectable="false" toolTip="{data.label}" />
            </mx:Component>
        </mx:itemRenderer>
    </mx:ComboBox>

</mx:Application>

I tried the first example on this page using “mx.controls.Text” for the “itemRenderer” property of ComboBox. I neither got a tooltip nor found the contents to be wrapped around. I am learning Flex. Your comments would be helpful to me.
