The Q_GADGET macro cannot be used in templates. It can however be useful to derive a template class from a Q_GADGET enabled base class to benefit from type safety features in C++ (e.g. the class could represent an id or handle for some C++ type). For proper wrapping of a QVariant with a gadget value in a QJSValue, the QMetaType::IsGadget flag must be set for the registered template instance type - which does not happen prior to the fix because IsGadgetHelper requires qt_check_for_QGADGET_macro to be defined in the registered class but not in an ancestor class - in other words: The class must declare Q_GADGET. To overcome this, IsGadgetHelper/IsPointerToGadgetHelper can now differentiate between a Q_GADGET flagged class (allowing automatic registration) and a derived class, e.g. a template class (forcing Q_DECLARE_METATYPE to be used explicitly).

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.
