Re: Struggling with LayerTabBar in unit test

[Regina Henschel <rb.henschel@xxxxxxxxxxx>]

Hi Stephan, hi Michael,

thank you. I have wondered about DLLPUBLIC, but never ask about it. 
Another piece learned.

I will try the SD_DLLPUBLIC approach. First I need to know, whether my 
idea for a test will work at all. Second step can be to find a better 
integration of the test.

Kind regards
Regina
