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? Thanks, Clarke

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. The Text and TextArea controls just truncate the text. I would like to add the Label-style "..." behavior to multi-line Text and TextArea controls. I talked to Doug at the last CFLunch, and he said: " You over-ride the data setter/getter for custom renderers, not what you were trying to do. Have a look at truncateToFit() inside UITextField.as. You might be able to model your component after Text.as or Label.as which extends Label which extends UITextField. truncateToFit() is where the truncation routine is, its public so over-rideable. " This makes sense and it looks like truncateToFit() may do what I want. Now, here are my questions: 1. truncateToFit() is a method of the UITextField object. Now, I know that TextArea.as has a UITextField. But, in general, what's the best way to see what other objects are inside of a control? 2. I know it's in there somewhere, but how do I access the UITextField. How do I get a handle to the internal object. 3. Both of the above questions may be the two ways to ask the same question -- I'm not sure. The other thing I want to know is what's the best practice way to reference an internal, contained object? 4. From looking at the Text Class, I think one thing Doug said was wrong. Text does not extend UITextField, it extends UIComponent. I think Text uses composition to "have a" UITextField. This is what I'm trying to understand. I think I have a good understanding of what I'm trying to do. It's just that the complexity of Flex can be overwhelming as I try to wade through all the ActionScript. I'm looking for ideas on how to best structure my search. Thanks for any advice!
