Up until now, notehead scheme has only been a StaffType property. If a Note is going to have its own notehead scheme, it seems fitting to do a bit of reorganization. Here is a summary of the changes made:
- Moved enum class NoteHeadScheme to NoteHead::Scheme, alongside NoteHead::Group and NoteHead::Type.
- Added HEAD_AUTO as a possible value for NoteHead::Scheme.
- Moved scheme2userName(), scheme2name(), and name2scheme() from class StaffType to class NoteHead.
- Renamed Pid::STAFF_NOTEHEAD_SCHEME to Pid::HEAD_SCHEME. This change is reflected in the Plugin API, with Element property staffNoteheadScheme being renamed to headScheme. This should not break too many existing plugins, because the NoteHeadScheme enum values have never been exposed until now. Speaking of which,
- Exposed the NoteHead::Scheme enum values to the Plugin API as NoteHeadScheme.HEAD_AUTO, etc. And finally, (and the main point of all of this):
- Added a property of type NoteHead::Scheme to class Note, and exposed it via the Inspector. If set to HEAD_AUTO (the default), the StaffType’s noteHeadScheme will be used. Otherwise, this will override the StaffType’s noteHeadScheme.
Improved the functionality of the playhead (a.k.a. the playback cursor) so that whenever the user selects an element, the playhead is automatically repositioned to the element's time position. Previously, this worked only for noteheads and rests, but it now works for note stems, beams, augmentation dots, accidentals, ties, slurs, articulations, time signatures, key signatures, clefs, tempo changes, dynamics, lines, barlines, breaks, spacers, measure numbers, text, and so on.
Special cases handled:
* Barlines. The playhead is moved to the start of the measure to the right of the barline, unless it's the last barline in either the entire score or the system, in which case the playhead is moved to the start of the measure to the left of the barline.
* Brackets always have a time position of zero, so the playhead is moved to the start of the first measure in the system that the bracket belongs to.
* Instrument names always have a time position of zero, so the playhead is moved to the start of the first measure in the system that the instrument name belongs to.
