This bug is -[NSMenu menuBarHeight] always returns 0.0f. It was filed on 2006-03-17 at 23:55.
UPDATE 2006-03-25: Uploaded test app to GeoCities.
Summary:
NSMenu‘s -menuBarHeight method always returns 0.0f. Even the main menu’s.
Steps to Reproduce:
- Call
[[NSApp mainMenu] menuBarHeight].
Expected Results:
The method returns 22.0f.
Actual Results:
The method returns 0.0f.
Regression:
None known.
Notes:
Appearance Manager (in the form of the GetThemeMenuBarHeight function) and NSMenuView (in its +menuBarHeight method) both return 22.0f, the correct height of the menu bar under Tiger.
The documentation for +[NSMenuView menuBarHeight] recommends using -[NSMenu menuBarHeight] instead.
This method is superseded in Mac OS X v10.4 by the NSMenu menuBarHeight instance method.
Following this advice would break one’s app on 10.4.3 through 10.4.5 (the bug exists on 10.4.5 as well).
The bug works with any menu — the main menu isn’t the only one. It’s just the most obvious menu to call that method on.
Workarounds:
Use GetThemeMenuBarHeight or +[NSMenuView menuBarHeight].

this bug still exists as of 2007.07.06 under 10.4.9
i haven’t yet checked to see if you can still use the NSMenuView class method workaround …
