If the active QWidget gets destroyed, then QWidgetWindow::focusObject will return nullptr. If then no other object takes focus, then we'd never emit change signals, and QGuiApplication's _q_updateFocusObject (which then informs the input context and emits signals) didn't get called. This left the input context with a dangling focus object pointer, which resulted in crashes. If the QWidget clears its focus, but the corresponding window doesn't know that it had focus, then fall back to the widget's focus widget to see if we have a change in focus, so that signals get emitted. Add a test case that shows that we didn't call _q_updateFocusObject by counting emissions of the QGuiApplication::focusObjectChanged signal, which we emit in this function. The signal is emitted more than once both when showing a widget, and now also when destroying a widget that has a focus child. The former is a previous issue, the latter is an improvement to not emitting the signal at all.

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.
