- An icon on the left defined by the
iconFieldoriconFunctionproperty. - A single-line text label next to the icon defined by the
labelFieldorlabelFunctionproperty. - A multi-line message below the text label defined by the
messageFieldormessageFunctionproperty. - A decorator icon on the right defined by the
decoratorproperty.
To apply CSS styles to the single-line text label, such as font size and color,
set the styles on the IconItemRenderer class.
To set styles on the multi-line message, use the messageStyleNameM style property.
The following example sets the text styles for both the text label and message:
<fx:Style>
.myFontStyle {
fontSize: 15;
color: #9933FF;
}
</fx:Style>
<s:List id="myList"
width="100%" height="100%"

A user-supplied function to run on each item to determine its icon.
The iconFunction property overrides
the iconField property.
You can supply an iconFunction that finds the
appropriate fields and returns a valid URL or object to be used as
the icon.
The icon function takes a single argument which is the item in
the data provider and returns an Object that gets passed to a
spark.primitives.BitmapImage object as the source
property. Icon function can return a valid URL pointing to an image
or a Class file that represents an image. To see what other types

the image is stretched to fit.
When set to BitmapScaleMode.LETTERBOX ("letterbox"),
the image is scaled with respect to the original unscaled image's
aspect ratio.
When set to BitmapScaleMode.ZOOM ("zoom"),
the image is scaled to fit with respect to the original unscaled image's

If labelFunction = labelField = null,
then use the label property that gets
pushed in from the list control.
However if labelField is explicitly set to
"" (the empty string), then no label appears.
The host component of the item renderer can use the
itemToLabel() method to convert the data item
to a String for display by the item renderer.
For controls like List and ButtonBar, you can use the
labelField or labelFunction properties
to specify the field of the data item that contains the String.
Otherwise the host component uses the toString() method
to convert the data item to a String.
