window below, so that it stays in bottom. Note that
you shouldn't assume the window is definitely below afterward,
because other entities (e.g. the user or window manager) could not keep it below,
and not all window managers support putting windows below. But
normally the window will be kept below. Just don't write code
that crashes if not.gtkWindowSetKeepBelow(object, setting)objectsettingwindow below other windowsGtkWidget.
Note that, according to the Extended Window
Manager Hints (http://www.freedesktop.org/Standards/wm-spec) specification, the above state is mainly meant
for user preferences and should not be used by applications e.g. for
drawing attention to their dialogs.
