Creates an ApplyFormatOperation object.

This code snippet shows a use of the ApplyFormatOperation class. After an operation of this type is executed, the font size of the new TextLayoutFormat is gathered, which can be used to update a display label or menu.

package flashx.textLayout.operations.examples
{
    import flashx.textLayout.elements.TextFlow;
    import flashx.textLayout.events.FlowOperationEvent;
    import flashx.textLayout.operations.ApplyFormatOperation;
    
    public class ApplyFormatOperation_example
    {
        public function attach(textFlow:TextFlow):void
        {
            textFlow.addEventListener(FlowOperationEvent.FLOW_OPERATION_BEGIN, opEndHandler);
        }
        
        public function opEndHandler(evt:FlowOperationEvent):void { 
            var flowOp:ApplyFormatOperation = evt.operation as ApplyFormatOperation; 
            if (flowOp is ApplyFormatOperation && flowOp.leafFormat != null && evt.cancelable) {
                //determine the font size - can be used to update a menu or label
                var fSize:int = flowOp.leafFormat.fontSize;
                if (fSize > 18)
                    evt.preventDefault();
            }
        }
    }
