    Comments:

    1.
    In this demo we use AddNamedCheckpointEx method.
    It has second parameter - RaiseEvent: Boolean.
    If set to True, RichView will generate event when this checkpoint
    becomes visible

    2.
    Checkpoints with RaiseEvent=True can be displayed with different color
    than other checkpoints.
    Color of "normal" checkpoints: RVStyle->CheckpointColor;
    Color of "RaiseEvent" checkpoints: RVStyle->CheckpointEvColor
