I don't think that updating menus from other threads is allowed by design.
Surly not, I just thought, there might be an easy way to make this thread safe.
My suggestion is to take a look on how the dynamic updating recordings menu works in vdr-1.3.33 and newer. Basically, a background thread collects the data, and the foreground thread updates the menu on the next ProcessKey(kNone) call.
Ok, I see - I already thought about this. It just didn't felt right, because I see ProcessKey() as some kind of message loop, which I don't want to give too much responsibilities. In my current design, the menu has a presenter (MVP), which is an observer that get's notified by the thread. I will probably let the presenter collect the items to be updated and when the menu comes across a kNone in ProcessKey, it lets the presenter update any items it may have in it's "update queue". Surely not the best solution, but maybe I will find a better one later on.
