Christian Ehrlicher ccf61c3480 QWidget: don't re-polish when style did not change
Don't call style->unpolish()/polish() when the old and new style did not
change which might happen when setting a style sheet as this might
create an infinite loop and the style (re)sets some window attribute.
Bailing out early is not an option here as newStyle might be a nullptr so q->style() will fall back to the application default style.

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.
