Great prototype, works fast! Thanks.

On mouse over the fields, the selection (on mac, the coloring of the line indicating current position in the list) does not change. Following is an example of how this works for selection of linkage:

a

and how the line for Zzz3 is not marked with blue for selection of annotation:

Filter looks like an text entry box. When I first open the menu, I wanted to click somewhere inside the box to activate it and have the caret show, but action closes the pull down menu. I understand that the problem is with deciding which Qt widget is in focus. @markotoplak, @astaric, can you look at this and comment.

Works great for me as well. We have to start using this component in other widgets to discover and fix any hidden bugs.

I would prefer to have home/end key jump around on the search line when editing the query.

It is indeed great.
I suggest we merge this right after the current release and start adding it to widgets so that the next release has a batch of new combo boxes.
Both of @thocevar's comments make sense, I would also like to see home/end move the cursor where I am typing. But tweaks can also be made later, this has been open for too long already, so I don't mind merging even as it is now.

Can you please test Home/End keys again to ensure they correspond to standard platform behavior.
