When a QWindow is parented into another window, either via its constructor, or via setParent(), we also update the QObject parent of the window. This in turn sends ChildAdded and ChildRemoved events to the new and old parent of the window, as well as ParentAboutToChange and ParentChange to the window itself. But at the point when these events are sent, the QWindow parent relationship has not been fully established. We have not updated d->parentWindow, nor have we propagated the parent relationship to the platform window. This is problematic because clients can not use these events to react to window parent changes synchronously. For example. trying to raise a child window when added to a parent is not going to work, because at that point the child window isn't a native child of the parent. Instead of re-using the QObject events for QWindow, like QWidget does, by delaying the events or sending them manually at a point when the window parent relationship has been fully formed, we opt to add new dedicated events.

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.
