I had looked around, but didn't find a test, which I could use as 
template for my test.

And those familiar with Draw/Impress have a lot of more important things 
to do.

I have made a little bit progress. I have initialized the size of the 
ContainerWindow of the Frame with meaningful values (size defaults to 
zero) and set it to Show(true). Now I get a LayerTabBar with correct 
outer rectangle.

But the rectangles of the single tabs are empty and therefor the hit 
test for the mouse event fails. Other properties of the tabs like id, 
label text and associated layer are correct.

So I still need to investigate what is missing.

Kind regards
