If a widget received a DragEnter event that it didn't accept, then the UnderMouse widget attribute gets set. But the drag manager never got a drag target, so the DragLeave event was never delivered, leaving the UnderMouse attribute set incorrectly. We always need to send DragLeave events to the receiver, even if the DragEnter or DragMove was not accepted. Otherwise we are not in balance, and the UnderMouse attribute will remain set. This is a change of behavior and a very old bug, so only fixing this in unreleased branches. Test case added to verify that explicitly generated drag events result in the correct enter/leave events. [ChangeLog][QtWidgets][QWidget] DragLeave events are now always sent to the widget the mouse is leaving, even if it didn't accept the DragEnter event.

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.
