Method Details
- run
  
  void run(PositionType pos)
  
  Emitted whenever user-initiated scrolling makes the scrolled window exactly reach the lower or upper limits defined by the adjustment in that orientation.
  A similar behavior with edge resistance is provided by the Gtk.ScrolledWindow::edge-overshot 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(org.gnome.gtk.PositionType) is executed.
- toCallback
  
  default MemorySegment toCallback(Arena arena)
  
  Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int) method.
  
  Specified by:
  
  toCallback in interface FunctionPointer
  
  Parameters:
  
  arena - the function pointer will be allocated in this arena
  
  Returns:
  
  the native function pointer
