Good afternoon,
I realize that the list has been dominated by Leopard issues of
late, so I
thought I could mix it up with a problem on Mac OS X 10.3.9
(Panther). <g>
In testing, somebody with an older system is reporting that our
application
does not start. Our Panther test system, running the same version
(10.3.9)
on a G4 Mac Mini, works just fine. (The failing system is a much
slower
PowerBook G4 with half the memory, if that matters.)
With an instrumented build, we determined that a critical modal
dialog box
is not displaying correctly. The RunAppModalLoopForWindow()
function is
returning error code -5615 (windowWrongStateErr). Even though this
is not
a documented return code for that function, everything I can find (not
much) says that this could happen if the target window is hidden,
and I was
able to verify this by deliberately hiding the dialog box.
The OS X 1.4 release notes suggest that this is a known bug with this:
"RunApplicationModalLoopForWindow[sic] no longer returns
windowWrongStateErr if the process is hidden (3703740)."
(http://developer.apple.com/releasenotes/Carbon/RN-HIToolbox/index.html
)
My code, literally, says:
ShowWindow ( Dialog );
SelectWindow ( Dialog );
_Error = RunAppModalLoopForWindow ( Dialog );
I do not know how the dialog box could be hidden at this point
('Dialog' is
a WindowRef from a correctly loaded Nib), and I cannot figure out
why it
would work on one system but fail on another. I even tried using
TransitionWindow() as an attempt to assure that the window was
visible.
Does anybody know any method to work around this issue (or see a
problem
with my implementation)?
This game is supposed to ship next week, and it would be a shame to
not
(officially) support OS X 10.3 due only to this bug.
Thanks for any help you can provide.
