The current implementation of qIsNull only returns true if the value is positive zero. This behaviour is not useful for use cases like QPointF::isNull, where QPointF(-0, -0).isNull() will return false. There doesn't seem to be a reason why the function exhibits this behaviour (-0.0 is not accounted for in the unit tests), and for the case of QSizeF::scale it causes a bug: qIsNull is used to check for division by 0.0 before it proceeds, which fails in the case of -0.0.

This directory contains autotests and benchmarks based on QTestlib. 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.
