    • run

      void run(PositionType pos)

      Emitted whenever user initiated scrolling makes the scrolled window firmly surpass the limits defined by the adjustment in that orientation.

      A similar behavior without edge resistance is provided by the Gtk.ScrolledWindow::edge-reached signal.

      Note: The pos argument is LTR/RTL aware, so callers should be aware too if intending to provide behavior on horizontal edges.

    • upcall

      default void upcall(MemorySegment sourceScrolledWindow, int pos)
      The upcall method is called from native code. The parameters are marshaled and run(PositionType) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment, int) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
      the native function pointer
