Selective point-and-click

For some interactive applications, it may be desirable to only include certain point-and-click items. For example, if somebody wanted to create an application which played audio or video starting from a particular note, it would be awkward if clicking on the note produced the point-and-click location for an accidental or slur which occurred over that note.

This may be controlled by indicating which events to include:

• Hard-coded in the .ly file:

  \pointAndClickTypes #'note-event
  \relative {
    c'2\f( f)
  }
  

  or

  #(ly:set-option 'point-and-click 'note-event)
  \relative {
    c'2\f( f)
  }
  

• Command line:

  lilypond -dpoint-and-click=note-event example.ly
  

Multiple events can be included:

• Hard-coded in the .ly file:

  \pointAndClickTypes #'(note-event dynamic-event)
  \relative {
    c'2\f( f)
  }
  

  or

  #(ly:set-option 'point-and-click '(note-event dynamic-event))
  \relative {
    c'2\f( f)
  }
  

• Command line:

  lilypond \
    -dpoint-and-click="(note-event dynamic-event)" \
    example.ly
