Sets the tip area of @tooltip to the area @path, @column and @cell have
in common. For example if @path is %NULL and @column is set, the tip
area will be set to the full area covered by @column. See also
gtk_tooltip_set_tip_area().
Note that if @path is not specified and @cell is set and part of a column
containing the expander, the tooltip might not show and hide at the correct
position. In such cases @path must be set to the current node under the
mouse cursor for this function to operate correctly.
See also gtk_tree_view_set_tooltip_column() for a simpler alternative.
