Methods

  • Adds a child Element to the Element, which lets it inherit the same style as the parent when setGroupStyle() is called.

    Examples of children are noteheads and stems. Modifiers such as Accidentals are generally not set as children.

    Note that StaveNote calls setGroupStyle() when setStyle() is called.

    Parameters

    • className: string

    Returns Tickable

  • Optional, if tickable has modifiers, associate a Modifier.

    Parameters

    Returns Tickable

  • Add self to the provided ModifierContext mc. If this tickable has modifiers, set modifierContext.
