Actually, you tripped over one of the subleties of the Flex Framework. Scrollbars are not always calculated into the width/height of a component and the content does not always resize. The scrollPolicy affects the computation, and the component determines whether to resize the content. This is done because of the top-down layout rules in Flex where if a scrollbar appeared at the top and forced content resize, the content might be forced to put up scrollbars and you end up with a cascade of scrollbars on the screen. The rules are: scrollPolicy="off". Scrollbars are not factored into the measured size (because they'll never be shown) scrollPolicy="on" Scrollbars are factored into the measured size (because they are always shown) scrollPolicy="auto" Scrollbars are not factored into the measured size and if forced to appear will clip content, except for the list classes which will try to resize the width of the content.

Sorry about that, I went to create a simple example and realized it isn't Flex that's not very smart, but rather me. :) Next time I'll try to create the simple example BEFORE coming in here and making bold and outrageous claims. ;) Thanks for the help. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Are you sure the GridItems resize and don't just get clipped by the > scrollbar?
