I see. Any particular reason for using Canvas? If you're laying them out vertically as in this example, then I think you could use VBox and your problem would be solved (along with visible/includeInLayout). The problem here is that Canvas will start counting from the absolute position of the top-most visible item (y="1000"), so it'll still leave 1000 px. blank space. You don't have that with VBox. > I'm trying to make scrollRect crop the canvas. I'm able to restrict > the view, but I can't make it scroll. Take this example: scrollRect or mask is just not going to work nicely with a Flex container. I wouldn't go there at all. -- manishjethani.com
