RE: Question Again, Focusing Mechanism

[S.J.Chun]

The flickering problem in Windows is caused by the part in NSMenu.m: -canBecomKeyWindow

in NSMenuPanel. It always returns YES even when application main window is.

If I cammented out the "condition and return YES" part so that it always return NO(I know this is

wrong way of fix, but my intension is not fix, just a testing :-), the flickering problem does not

occur.

 

Why [[NSApp mainMenu] window] condition is used? Does it always return NSMenuPanel ?

 

Thanks in advance.
