What to do about this long error: This application is trying to draw a very large combo box

I cannot find any reference to this on SO.. The full message is:

"This application is trying to draw a very large combo box, 32 points tall. Vertically resizable combo boxes are not supported, but it happens that 10.4 and previous drew something that looked kind of sort of okay. The art in 10.5 does not break up in a way that supports that drawing. To avoid breaking existing apps, NSComboBox in 10.5 will use the 10.4 art for large combo boxes, but it won't exactly match the rest of the system. This application should be revised to stop using large combo boxes. This warning will appear once per app launch."

Any ideas what to do about it?

I made the box in IB, and don't think I did anything special to create it.

Solution

  • I had the same error. When I dragged comboboxes out of a Stack View, Xcode messed up their heights. To correct the problem, I added height constraints of 22 to each of them. That caused the warning. When I deleted all the height constraints, the warning went away. The comboboxes didn't revert to the crazy heights they had when I dragged them out.
