whether or not the given tooltip context points to a item
This function is supposed to be used in a "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. x and y will always be converted to be relative to icon_view's bin_window if keyboard_tooltip is FALSE.
