It would probably help a lot if you can post a small test app the shows what you're talking about. Keep it as simple as possible to illustrate your problem.
But my first instinct is that it's kind of an age-old problem in programming with scrollbars. Say you have an element that is 500 pixels wide, just wide enough to show everything it contains. Then it gets a lot of info in it, which causes it to need a vertical scrollbar. Well, that scrollbar then steals some width from that 500, so that now the element can only be, say, 484 pixels wide because there's a scrollbar taking up the next 16 pixels. Well, now if you have scrollbars set to automatically pop up when the element isn't wide enough to display the text width, the horizontal scrollbar shows up, too. The fix for this in flex is to set the horizontal widths as a % of the parent's width. That way when the vertical scrollbar pops up, the element and hence its children will resize to be smaller to accomodate the scrollbar. If this isn't clear, post your example and I can show you the changes to fix it. On Wed, Sep 10, 2008 at 6:19 AM, itdanny2002 <[EMAIL PROTECTED]> wrote: > I create Vbox with fixed width.
