Button toggle in flex

Does flex have a button toggle class or something???
So once it has been clicked the function is disabled until another state is choosen

<mx:LinkButton label=“Value ('000s €)” click=“changeState(‘01_wm_2’);” icon="@Embed(source=‘assets/box_white.png’)" styleName=“dashButton” width=“100%” height=“22”/>

Me thinks I am going to need to write it into changeState.
anyone got a quick example from a previous experiment or something??
