JWANKERL@UTCVM.BITNET ("Josef W. Wankerl") (04/13/89)
I've been writing a program (in assembler) that needs a window with the data height greater than $FFFF. Is there any way to stuff everything into the window?? Also, I've been wondering about some tricks to do with the Menu Manager. How would you code: Hierarchical menus, Tear off menus, and Menus inside a window?? -Gonzo

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. >Also, I've been wondering about some tricks to do with the Menu Manager. >How would you code: > Hierarchical menus, > Tear off menus, >and Menus inside a window?? > 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. ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc. --- Developer Technical Support INTERNET: keith@apple.com UUCP: {decwrl, hoptoad, nsc, sun, amdahl}!apple!keith "Argue for your Apple, and sure enough, it's yours" - Keith Rollin, Contusions

If you're using a data area larger thatn 65535, you have to translate this into your REAL origin INTERNALLY (since QuickDraw space isn't that big!) before drawing. Needless to say, this can get really hairy. I would suggest that you NOT use TM's scrollbars. It's a little more work to keep track of the controls yourself, but you end up with MUCH more control over their behavior. (This is the approach we used in AWGS; none of the modules use TM scrollbars or grow boxes.) -- Jeff Erickson \ Internet: krazy@claris.com AppleLink: Erickson4 Claris Corporation \ UUCP: {ames,apple,portal,sun,voder}!claris!krazy 415/960-2693 \________________________________________________________ Soon: 408/987-7309 / "I'm so heppy I'm mizzabil!" -- Krazy Kat
