Custom Scrollpane type thing

Hello, Im not the best with flash and Im in need of some help making a scroll pane that shows a externally loaded html or swf file (I would prefer html easier to make quick small changes) and it has to have custom up and down arrows. If I were to change the external file to make it have a greater height I want the scroll pane to continue working with out me editing the pane. I made a little gif to try and explain what I need more clearly because I can barely understand what Im talking about :stuck_out_tongue:


dont worry it wont look like this. Thanks.

Do you realize that there already is a scrollpane component in flash?
If you like to build one yourself you can extend from that class to make your custom scollpane.
