VFR defines only the content and not the placement of items and by default
items are listed vertically.We use the down arrow key to navigate each
item.How do i design a setup screen where items are listed horizontally and
i use the next arrow to move on to the next item on the list.I want to
design something like a bios setup screen where we use next arrow to
traverse various menu items like main,advanced, security etc.
Thanks..
