I would suggest extending the class by adding a property numLines to the textarea - that property would take its value from the textField.numLines, which is a protected property inside TextArea that represents the actual textField used to render text. Then you can call TextArea.getLineMetrics() and multiply it by the number of lines you got from numLines;
This is just from the top of my head but this looks like a good solution to me. 2008/12/11 blc187 <[email protected]> > does anyone know of an existing component that can truncate multiline > text? > > I'm looking to either use an already made one, or create my own > multiline TextArea and be able to truncate when the textHeight reaches > more than the set height of the component. > > So far I haven't been able to get a correct height for it, I keep > getting a much larger height than it actually is because the > textHeight reflects the size of the htmlText, even though I'm only > setting text, not htmlText on it. > > Is there a way to get a more accurate textHeight? > > >
