This function is supposed to be used in a #GtkWidget::query-tooltip signal handler for #GtkTreeView. The @x, @y and @keyboard_tip values which are received in the signal handler, should be passed to this function without modification.
The return value indicates whether there is a tree view row at the given coordinates (%TRUE) or not (%FALSE) for mouse tooltips. For keyboard tooltips the row returned will be the cursor row. When %TRUE, then any of @model, @path and @iter which have been provided will be set to point to that row and the corresponding model. @x and @y will always be converted to be relative to @tree_view’s bin_window if @keyboard_tooltip is %FALSE.
