Hi, I want to inherit from TextArea and just tweak it's visual appearance when the control is disabled and the user has clicked on it (essentially I want to draw a red square around the outside).
How is the best way to do this? I tried overriding updateDisplayList, but I couldn't draw anything in there. Do I need to make a programmatic skin, or do I need to make a new control, one which is based on UIComponent, but has a TextArea contained on it? Also - If I create a new component from scratch, say from inheriting from Sprite, what functions do I need to override in order to get it to paint / resize / update correctly? i.e. In windows, I know I need to override WM_PAINT / OnPaint, and then to cause a repaint I can do InvalidateRect() or Update() to cause immediate repaint. What is the equivalent in Flex? Thanks, Mark
