If you set verticalScrollPolicy="on" then the scrollbars will be factored in

This is a decision made by the Flex team to avoid having to double measure() stuff when adding scrollbars to a container. -Josh On Wed, Jul 23, 2008 at 3:02 PM, Richard Rodseth <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: Below is code for a scrolling container of one child - a highly simplified version of the tiling container I've been wrestling with off and on for way too long now. The component below sizes the first/only child to fit within it, with some padding, but respects the minimums of the child, adding scroll bars if necessary. I discovered this evening that setting measuredMinWidth/Height in the measure() method was what was messing things up. With that removed, this component (and the more complex tiler) behaves properly, except that the scollbars are drawn over the right/bottom padding. What is the appropriate way to compensate for that? Adding a fudge factor to the measured values, or removing it from the value passed to setActualSize in UDL had no effect at all.
