Virtual Method
GtkSortercompare
Declaration [src]
GtkOrdering
compare (
GtkSorter* self,
GObject* item1,
GObject* item2
)
Description [src]
Compares two given items according to the sort order implemented by the sorter.
Sorters implement a partial order:
- It is reflexive, ie a = a
- It is antisymmetric, ie if a < b and b < a, then a = b
- It is transitive, ie given any 3 items with a ≤ b and b ≤ c, then a ≤ c
The sorter may signal it conforms to additional constraints
via the return value of gtk_sorter_get_order()
.
Return value
Returns: | GtkOrdering |
