How can I detect when the last container in my flow is full?

I have a bunch of linked containers which I am flowing text through. How can I detect when the text has filled a container? there's an overflowPolicy so I assume this can be detected.

Text layout framework

Hi,

I used this :

private function IsOverset(textFlow:TextFlow):Boolean

{

var zeComposer:IFlowComposer=textFlow.flowComposer;

var iTextLen:int=textFlow.textLength;

var iNoController:int=zeComposer.findControllerIndexAtPosition(iTextLen - 1);

return (iNoController == -1);

}

HTH,

short lived I'm afraid. I only ever get -1 with this ...

var containerIndex:int = textFlow.flowComposer.findControllerIndexAtPosition(textFlow.textLength);
if(containerIndex==-1) textFlowCompleteHandler();

I'm detecting this as the flow is created. The textFlow.length is being set correctly.

Any ideas?
