示例1: layout
void LyricsLine::layout()
{
if (lyrics()->ticks() > 0) { // melisma
setLineWidth(Spatium(MELISMA_DEFAULT_LINE_THICKNESS));
// Lyrics::_ticks points to the beginning of the last spanned segment,
// but the line shall include it:
// include the duration of this last segment in the melisma duration
bool ticksSet = false;
Segment* lastSeg = score()->tick2segment(lyrics()->endTick(), false, Segment::Type::ChordRest, false);
if (lastSeg) {
// if last segment found, locate the first non-empty ChordRest
// in the same staff of this LyricsLine and use its duration
int firstTrack = (track() >> 2) << 2;
int lastTrack = firstTrack + VOICES;
for (int i = firstTrack; i < lastTrack; i++) {
ChordRest* cr = static_cast<ChordRest*>(lastSeg->elementAt(i));
if (cr) {
setTicks(lyrics()->ticks() + cr->durationTicks());
ticksSet = true;
break;
}
}
}
// no suitable ChordRest found? go to the end of the last known segment
if (!ticksSet)
setTicks(lyrics()->ticks());

Note* nextChordNote(Note* note)
{
int track = note->track();
