Toggle Widget On / Off

Just getting back to Flex API after two years in the JS API. Please forgive if this seems terribly rudimentary....I would like toggle the LayerList widget on when the user selects a search result. For example, within the SearchWidget.mxml: (my stuff in Bold Italic)

private function clickSearchResult(event:Event):void
{
if (resultFeatureLayer.visible)
{
var searchResult:ResultItem = ItemRenderer(event.target).data as ResultItem;
if (searchResult.geometry)
{
if (searchResult.geometry.type == Geometry.MAPPOINT)
{
if (map.scale > zoomScale)
{
map.scale = zoomScale;
}
}

map.zoomTo(searchResult.geometry);
TOGGLE On LayerList Widget Here!!!!!
}
clearTimeout(hitimer);
hitimer = setTimeout(showHighlight, 300, [ searchResult ]);
}
}
