This function is supposed to be used in a #GtkWidget::query-tooltip signal handler for #GtkIconView. 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 an icon view item at the given coordinates (%TRUE) or not (%FALSE) for mouse tooltips. For keyboard tooltips the item returned will be the cursor item. 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.
