Instead iterating through all rows to get the number of hidden items, iterate over the hidden items which are fewer items. Also don't create a temporary vector with visible flow positions by remembering the count of hidden items before the working index and adjusting them appropriately which gives a significant performance boost when working with a large data set.

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.
