I know I've done this before, but I can't remember where and trawling through the documentation isn't helping me.
Basically I want to add something to a Canvas that is a 100% of it's internal size - so as the Canvas grows to add children (as scrolling is enabled) I want my child to still be 100% the size of the Canvas' internal area. If I set it's percentWidth & percentHeight to 100 then it just sizes up to the displayed portion of the canvas, same goes for the unscaledWidth & unscaledHeight values passed to updateDisplayList() they appear to be the visible dimensions of the Canvas. What I need is the width + it's scroll, so that's why I'm calling it the internal size of the Canvas. I've looked at CanvasLayout but I don't think that really helps me as the layout object is private to the Canvas. Any ideas are greatly appreciated.
