- An icon on the left defined by the
iconField
oriconFunction
property. - A single-line text label next to the icon defined by the
labelField
orlabelFunction
property. - A multi-line message below the text label defined by the
messageField
ormessageFunction
property. - A decorator icon on the right defined by the
decorator
property.
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%" labelField="firstName"> <s:itemRenderer> <fx:Component> <s:IconItemRenderer messageStyleName="myFontStyle" fontSize="25" labelField="firstName" messageField="lastName" decorator="@Embed(source='assets/logo_small.jpg')"/> </fx:Component> </s:itemRenderer> <s:ArrayCollection> <fx:Object firstName="Dave" lastName="Duncam" company="Adobe" phone="413-555-1212"/> <fx:Object firstName="Sally" lastName="Smith" company="Acme" phone="617-555-1491"/> <fx:Object firstName="Jim" lastName="Jackson" company="Beta" phone="413-555-2345"/> <fx:Object firstName="Mary" lastName="Moore" company="Gamma" phone="617-555-1899"/> </s:ArrayCollection> </s:List>MXML SyntaxHide MXML Syntax
