indicating whether the row should be shown or not, or
based on the return value of a visibility function, which is passed
the <code><a href="Graphics-UI-Gtk-ModelView-TreeModel.html#t:TreeIter">TreeIter</a></code> of the row and returns a Boolean indicating whether the row should
be shown or not.
</li><li> Set a different root node, also known as a "virtual root". You can
pass in a <code><a href="Graphics-UI-Gtk-ModelView-TreeModel.html#t:TreePath">TreePath</a></code> indicating the root node for the filter at construction
time.
