Issue introduced by a68e4f3b96a82a93898f381e8ddc7f50f9c89d40 ("Use the new QMetaType API in QVariant") in 6.0, which removed the d.is_null reset at the same time as it replaced the std::destroy_at / std::construct_at pair with an assignment operation. [ChangeLog][QtCore][QVariant] Fixed a bug that would allow the class to keep returning isNull() = true even after calling setValue().

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.
