What your working code looks like and how it is initiated?
I also use it in CAL, altough I access the RibbonBar directly not through an adapter. Nevertheless it doesn't work.
Maybe it is really a CAL related issue.
I have also noticted one thing.
In my application every module has a possibility to register its own tab in the RibbonBar. At first none of them apeared after the window came up. When I increased the initial size of the window, suddenly one tab became visible. Unfortunately the rest of
the them I add later during the program execution don't show up at all.
Any thoughts on that?
As I see it, it is some kind of a measuring and repainting issue.
