public function previousThumbGroup():void
ThumbGrid Version: ThumbGrid 1 and 2
Language Version: ActionScript 3.0
Player Version: Flash Player 9.0.0.0
Loads the thumbnail group before the current one in view. The method will loop back and load the last thumbnail group if thumbLoop is set to "On", or stop (and ignore the request) if set to "Off," if the currently active thumbnail group is the first one.
In this example, a button on the stage with an instance name of "my_btn" requests the previous thumbnail group:
my_btn.addEventListener("click",afterClick);
function afterClick(e:MouseEvent):void {
my_tg.previousThumbGroup();
}
