Cocoa Tk warning message

[Steve Landers]

When I run Tk Cocoa 8.5.7 on MacOS X 10.6.1 I get the following  
message on stderr ..

         setCanCycle: is deprecated.  Please use setCollectionBehavior instead

Is it a known issue? I can't find anything about in the SF tk bug  
tracker.

I've gotten reports of this warning, but I'm not sure it's a problem.
Perhaps Daniel can advise when he's back from leave as maintainer.

Hi Steve,

the warning is harmless, but see -setCanCycle: usage below (from
tkMacOSXWm.c ApplyWindowAttributeFlagChanges()):
i.e. setCanCycle use on 10.6 occurs only if you build your binary on
10.5 but deploy on 10.6

As mentioned in the README IIRC, the recommendation is to build on the
highest OS release you want to be able to run on (i.e. 10.6) with the
lowest MACOSX_DEPLOYMENT_TARGET setting you need to support (e.g.
10.5). This ensures that you get the benefit of any 10.6-specific
features in the codebase, like the use of
NSWindowCollectionBehaviorParticipatesInCycle below.

Cheers,

Daniel


#if MAC_OS_X_VERSION_MAX_ALLOWED >= 1060
            if (newAttributes & kWindowDoesNotCycleAttribute) {
                b |= NSWindowCollectionBehaviorIgnoresCycle;
            } else {
                b |= NSWindowCollectionBehaviorParticipatesInCycle;
            }
#endif
            [macWindow setCollectionBehavior:b];
#if MAC_OS_X_VERSION_MIN_REQUIRED < 1060
            if (((changedAttributes & kWindowDoesNotCycleAttribute) || initial)
#if MAC_OS_X_VERSION_MAX_ALLOWED >= 1060
                    && tkMacOSXMacOSXVersion < 1060
#endif
            ) {
                [macWindow setCanCycle:
                        !(newAttributes & kWindowDoesNotCycleAttribute)];
            }
#endif
