I posted the question on making a Text control do this on the flexcomponets list. I got " Yes, you can override truncateToFit in a subclass of UITextField to make it work with multiline text. I did it once a while back, and it wasn't very difficult. If I can find the code, I'll post it on my blog and link to it here.
Josh Tynjala www.zeuslabs.us" as a response, hope he posts something, eh? on exploring the framework....as nice as those posters are on the wall, so far my experience has been just delving in and hacking it up, yeehaw! I use the docs heavily then open the source to try and see. At which point I notice that I'm sapping up the time, a few minutes later have to jump ship or drop anchor as they say. Maybe a good topic for upcoming meeting? DK On 4/24/07, Clarke Bishop <[EMAIL PROTECTED]> wrote:
Thanks Doug! The other part of my question is about exploring the Flex Framework. What's the best way to get started? Suppose I want to see what's contained inside the Text Class. I know how to use the docs to see the Text Class properties, methods, events, etc. But, what about other objects in the class?

Yeah, the API is quite daunting to say the least. But hey, its smaller than Java! ;) DK On 4/23/07, Clarke Bishop <[EMAIL PROTECTED]> wrote: > > In Flex 2, if the text is too long for a Label control, Flex truncates > the text and adds a "..." to the end.
