QAppearance not found...

[katche70]

i update to latest version. but it always said:
Property 'appearance' not found on object of type 'QLabelElement *'

What is wrong? in demo Version all is fine.
It is necessary to include Appearance?

All QAppearance files are included in Project.

Had the same problem. You have to add
#import "QElement+Appearance.h"
