In C++17, unqualified lookup doesn't find function templates that require ADL from a call with explicit template arguments, unless another function template of that name is in scope (otherwise, the < is parsed as operator less-than instead). P0846, merged for C++20, fixes this to repeat the name lookup, parsing the < as indicating a template. We have API in Qt (Tuple Protocol for some types, e.g. QPoint) that work for the purpose of Structured Bindings, but don't work for manual unqualified calls when P0846 semantics are missing, and we're adding more, to QVariant, so add a macro to handle the issue. The macro simply declares a function template overload of the given name for a throw-away struct, thereby bringing, for that one name, P0846 semantics into C++17. When we require C++20, we can drop this again. Amends: - |

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.
