It's a little more complicated than that, it needs to best-guess the correct size, and will re-order the components somewhat in order to attempt to make the best use of available space. I've got the initial functionality working, it just needs tweaks, edge case testing, and for me to figure out why it goes into an infinite updateDisplayList loop when it's asked to layout in less space than it needs ;-)
Also, I'm on some other tasks this morning, but hopefully back on this one this afternoon, so I should have some code to look at in a day or two. There's very little code actually in the overriden UIComponent methods too, so it should be reasonably easy to port to a Layout if Adobe decide to make Layout part of the official API. -Josh On Thu, Jun 19, 2008 at 4:07 AM, sleekdigital <[EMAIL PROTECTED]> wrote: > Couldn't you just make a VBox subclass and have it add HBoxes for the > rows?
