+    \title Restoring a Window's Geometry
+
+    \ingroup best-practices
+
+    This document describes how to save and restore a \l{Window
+    Geometry}{window's geometry} using the geometry properties. On
+    Windows, this is basically storing the result of
+    QWidget::geometry() and calling QWidget::setGeometry() in the next
+    session before calling \l{QWidget::show()}{show()}.
+
+    On X11, this might not work because an invisible window does not
+    have a frame yet. The window manager will decorate the window
+    later.  When this happens, the window shifts towards the
+    bottom/right corner of the screen depending on the size of the
+    decoration frame.  Although X provides a way to avoid this shift,
+    some window managers fail to implement this feature.
+
+    Since version 4.2, Qt provides functions that saves and restores a
+    window's geometry and state for you. QWidget::saveGeometry()
+    saves the window geometry and maximized/fullscreen state, while
+    QWidget::restoreGeometry() restores it. The restore function also
+    checks if the restored geometry is outside the available screen
+    geometry, and modifies it as appropriate if it is:
+
+    \snippet doc/src/snippets/code/src_gui_widgets_qmainwindow.cpp 0
+    \snippet doc/src/snippets/code/src_gui_widgets_qmainwindow.cpp 1
+
+    If those functions are not available or cannot be used, then a
+    workaround is to call \l{QWidget::setGeometry()}{setGeometry()}
+    after \l{QWidget::show()}{show()}. This has the two disadvantages
+    that the widget appears at a wrong place for a millisecond
+    (results in flashing) and that currently only every second window
+    manager gets it right. A safer solution is to store both
+    \l{QWidget::pos()}{pos()} and \l{QWidget::size()}{size()} and to
+    restore the geometry using \l{QWidget::resize()} and
+    \l{QWidget::move()}{move()} before calling
+    \l{QWidget::show()}{show()}, as demonstrated in the
+    \l{mainwindows/application}{Application} example.
