Hello
You cannot change the size of the buttons for the list box, what you would need is to use a command button that would alter the attributes for the list box everytime the user clicks on it. Use the SetCtrlAttribute with ATTR_FIRST_VISIBLE_LINE option set, that will allow you to move the list up or down programmatically.
I hope this helps
