Final fix for bug #373
------- Comment #13 From Christian Walther 2007-07-15 10:04:56 [reply] -------
Created an attachment (id=229) [details]
patch to reinstate the SDL cursor after an NSApplicationActivatedEvent
Oops, you're right. My testcursor.c has diverged so far from the original that
I missed that. In fact, now that I think about it, that issue isn't even
addressed by the cursor rectangle patch - it is only concerned with windowed
mode (and fixes the problem there as a side effect). The problem in fullscreen
is still the same as before. How about the attachment for a fix? (I can confirm
that [NSCursor set] doesn't seem to have any effect when called from
QZ_DoActivate().)
