And you cannot press the cancel button in the dialog?
That is a Mac-only problem?

Yes, the widgets are styled with style sheets, which are interpreted by the 
style. Apparently, this does not work on Mac - I assume Qt uses some native 
library there which is not as flexible as the styles for Linux.

The stylesheet is set in utilities/facedetection/assignnamewidget.cpp, line 
470. For debugging, uncomment line 106 of digikam/items/assignnameoverlay.cpp, 
then you can play with the stylesheet and immediately apply it when you press 
ok. It's the only way to develop style sheets, the documentation is not 
suitable to know if something works or not.
