[flexcoders] mx:Text - how to get number of lines of text?

[Paul Booth]

Hi,

I have an mx:Text control and I want to know the length of the last line. I
can do this with the following:

  var metrics:TextLineMetrics = myTextControl.getLineMetrics
(indexOfLastLine);

Trouble is, I don't the right value for 'indexOfLastLine' because I don't
know how many lines there are in the text control. I'm assuming I'm missing
something obvious, can someone tell me how to get the number of lines?

Thanks,

Paul.
