QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in the form of the cacheKeys QHash, but QPixmapCache::clear() didn't touch it, leading to the string data (as well as the Keys) being retained after any possible use. This can lead to memory slowly being eaten up, as reported in QTBUG-112200, and prevents a periodic calling of QPixmapCache::clear() from being a work-around for the issue in the bug report. Fix by clearing cacheKeys in QPixmapCache::clear(). This is designed as a low-risk enabler of a work-around, not a fix for the issue. The work-around enabled by this is periodic calling of QPixmapCache::clear(). [ChangeLog][QtGui][QPixmapCache] Fixed QString key data not being freed on clear().

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.
