Overlapped broken on the v2_develop branch using the BackgroundWorkerCollection scenario.

[BDisp]

Here is some of the issues after opening the scenario:

• After pressing F9 to open the MenuBar the keys navigations doesn't. Only work with mouse.
• After opening MenuBar->View->WorkerApp pressing F9 to opening the MenuBar the menu isn't position correctly. See image:

• Press enter do Run Worker, again for Start and wait until the result Work list: is open. Press again F9 to open the MenuBar and again the menu isn't position correctly. Seems that the application assumes that the MenuBar is on the focused view (OverlappedChildren) and not on the Application.OverlappedTop.
• Close the opened Work list: by clicking the Close button and an exception is throwed. See image:

• Another situation is when pressing F9 to open the MenuBar and we click outside the menu on another toplevel, the menu stays opened and it must be closed to allows selecting the other toplevel.

@tig maybe ou can fix this in the #3634?

BackgroundWorkerCollection will need to be rewritten with #3634. I do not understand the logic of that Scenario after hours of studying it. Maybe it's because threading confuses me in general.

What I would prefer is for you to rewrite it. I will let you know when progress on #3634 is far enough long for you to do this.

It it's to rewrite as a Toplevel with Window as subviews I prefer to delete it at all, because it uses a different methodology. You need to distinguish overlapped subviews from overlapped toplevels. The threading has nothing to do with the issues. MenuBar has bugs. It seems sometimes that an open menu is hidden but not effectively closed which will cause navigation behaviors issues.

Do you agree we need a good multi-threading example for v2.

Oh, and I meant #2491 when I wrote #3634 above.

The Threading scenario was created more for the threading examples. The BackgroundWorkerCollection was created to demonstrate more the MDI concept now called Overlapped. But I understand that the overlapped feature can work well with both concepts, although with different code:

• With overlapped top and overlapped childs.
• With overlapped top and subviews.

Closing.

I've added ensuring we have a good "Multiple overlapped, MDI-like views" example in #2491.
