  • Method Details

    • run

      void run(SorterChange change)

      Emitted whenever the sorter changed.

      Users of the sorter should then update the sort order again via gtk_sorter_compare().

      SortListModel handles this signal automatically.

      Depending on the change parameter, it may be possible to update the sort order without a full resorting. Refer to the Gtk.SorterChange documentation for details.

    • upcall

      default void upcall(MemorySegment sourceSorter, int change)
      The upcall method is called from native code. The parameters are marshaled and run(SorterChange) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment, int) method.

      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
