<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/08/21/setting-the-font-thickness-for-a-label-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        @font-face {
            src: local("Base 02");
            fontFamily: Base02Embedded;
        }
    </mx:Style>    

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="fontThickness:" direction="horizontal">
                <mx:HSlider id="slider"
                        minimum="-200"
                        maximum="200"
                        value="0"
                        snapInterval="10"
                        tickInterval="20"
                        liveDragging="true" />
                <mx:Label text="{slider.value}" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:Label id="lbl"
            text="The quick brown fox jumped over the lazy dog."
            fontFamily="Base02Embedded"
            fontSize="16"
            fontAntiAliasType="advanced"
            fontThickness="{slider.value}" />

</mx:Application>

View source is enabled in the following example.

You can also set the fontThickness style using an external .CSS file or <mx:Style /> block, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/08/21/setting-the-font-thickness-for-a-label-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        @font-face {
            src: local("Base 02");
            fontFamily: Base02Embedded;
        }

        Label {
            fontAntiAliasType: advanced;
            fontFamily: Base02Embedded;
            fontSize: 16;
            fontThickness: -200;
        }
    </mx:Style>    

    <mx:Label id="lbl"
            text="The quick brown fox jumped over the lazy dog." />

</mx:Application>

Or, you can set the fontThickness style using ActionScript, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/08/21/setting-the-font-thickness-for-a-label-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        @font-face {
            src: local("Base 02");
            fontFamily: Base02Embedded;
        }
    </mx:Style>    

    <mx:Script>
        <![CDATA[
            import mx.events.SliderEvent;

            private function slider_change(evt:SliderEvent):void {
                lbl.setStyle("fontThickness", evt.value);
            }
        ]]>
    </mx:Script>

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="fontThickness:" direction="horizontal">
                <mx:HSlider id="slider"
                        minimum="-200"
                        maximum="200"
                        value="0"
                        snapInterval="10"
                        tickInterval="20"
                        liveDragging="true"
                        change="slider_change(event);" />
                <mx:Label text="{slider.value}" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:Label id="lbl"
            text="The quick brown fox jumped over the lazy dog."
            fontFamily="Base02Embedded"
            fontSize="16"
            fontAntiAliasType="advanced" />

</mx:Application>
