    • run

      void run()

      Emitted at the end of a single user-visible operation on the contents.

      E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

    • upcall

      default void upcall(MemorySegment sourceEditable)
      The upcall method is called from native code. The parameters are marshaled and run() is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
