- Item 8494888 28-Sept-90 13:45PDT
-
- From: LOCKWOOD Savitar, Mike Lockwood,PRT
-
- To: MACAPP.TECH$ MacApp Technical
-
- Sub: MacApp/System 7 patch
-
- The following describes an INIT that I posted to the "General System 7.0
- Discussion" folder on AppleLink:
-
- MacAppPatch fixes an incompatability between applications written in MacApp 2.0
- final and early betas of System 6.0.6 and System 7.0. As mentioned on
- MacApp.Tech$ recently, MacApp assumes that Draw1Control does not move the
- ControlHandle passed to it. This assumtion worked fine until System 6.0.6 and
- System 7 came out. (This was fixed in the latest beta of 6.0.6, but remains a
- problem in System 7)
-
- MacAppPatch patches Draw1Control so that it calls HLock and HUnlock before and
- after executing the Draw1Control trap. This prevents MacApp 2.0 final from
- crashing.
-
- I wrote this so I could use Mouser and ViewEdit with System 7.0a12. It is not
- intended to be shipped with MacApp applications to make them compatible with
- System 7. You are free to do what you want with it, but I only recommend using
- it for development purposes only, and make no guarantees or warranties as to
- its performance or behavior on your (or anyone elses) Macintosh.
-
- I wish you all happy Mousing and ViewEditing in System 7!
