There *ARE* ways, but I can't think of any easy ones. The only one that I
would try doing is the same way that MacApp does it on the Macintosh; store
your position within your data as a longint in your own data structures. Then
translate it into some 16-bit value by taking the top 16 significant bits and
using it for your coordinates and scrollbar values.

Of these three, I've only seen the last one implemented on a GS. It is covered
in Apple IIGS Technote #3. Actually, that technote discusses the more specific
instance where one might want to install a menubar in a window's infobar, but
the technique is easily adapted to other cases.

Hierarchical and TearOff menus cannot be implemented without some serious
re-programming. There are no tricks that I am aware to implement these.
