Examples ( How to use this example )
ApplyLinkOperation_example.as
This code snippet shows a use of the ApplyLinkOperation
class.
Before an operation of this type is executed, the link being applied to this TextFlow
is verified. If the link is invalid,
the event is cancelled and the link is not applied.
package flashx.textLayout.operations.examples { import flashx.textLayout.elements.TextFlow; import flashx.textLayout.events.FlowOperationEvent; import flashx.textLayout.operations.FlowOperation; import flashx.textLayout.operations.ApplyLinkOperation; public class ApplyLinkOperation_example { public function attach(textFlow:TextFlow):void { textFlow.addEventListener(FlowOperationEvent.FLOW_OPERATION_BEGIN, opBeginHandler); } public function opBeginHandler(evt:FlowOperationEvent):void { var flowOp:FlowOperation = evt.operation; if(flowOp is ApplyLinkOperation && evt.cancelable) { //if link is invalid, cancel link operation if(!linkValid(flowOp.textFlow)) { evt.preventDefault(); } } } private function linkValid(tf:TextFlow):Boolean { //code to check inserted link text in this TextFlow for validity return false; } } }
