As it is, when a QWindowContainer's embedded window gains focus, the container doesn't report having focus and QApplication::focusWidget() will be nullptr. This is because when the embedded window gets focus, the container will clearFocus() on the old focus widget. To be able to set focus to the next focus widget (eg: as a result of a key tab event sent to the container's parent window), the container checks if its embedded window is already focused, and if so, forwards focus to its nextInFocusChain(). That is why it keeps track of the (old) focusWindow. The problem with the current behavior is that if we want to make focus navigation via key tabbing work and return focus *from within the window* back to the normal widget focus chain, the encapsulating widget needs to remember its focusWidget(), in this case the window container, in order to be able to set focus to the next/PrevInFocusChain(). That is why we now set the focus to the window container whenever its contained window gains focus. This means that QApplication::focusWidget() will be the window container if the contained window has focus. In this way, we don't have to call clearFocus() on the old focus widget, or keep track of focus windows, because calling setFocus() on the container will handle that. It is worth noting and probably documenting the following caveats: - even though the window container will be the qApp's focusWidget(), it won't directly handle keyboard events, but the contained window will - we won't be able to respect the window container's focusPolicy in this case, since the contained window will be activated from interactions inside it, no matter the container's focusPolicy [ChangeLog][QtWidgets][QWindowContainer] The window container will become focused if the contained window becomes focused. This implies that the QApplication::focusWidget() will be the window container if the contained window is the focus window.

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
