set minHeight/minWidth = 0 on the HBox that you want to have scrollbars. ________________________________

I wont bother with scaling yet.. but want to have the image in a smaller hbox with scroll bars enabled but cant seem to get it to work. It will display the entire image if I do not set width/height on the HBox but I cannot set a limit to the size of the Hbox. Anything I may be missing?

Pretty new with flex, so let me know if this is a bad approach. >
