Fixup for 99c7b0d746
triggerLayout() and triggerLayoutAll() implementations in Element
have an optimization that allows to avoid triggering layout for
elements not yet added to a score by checking the element's parent.
This optimization is not suitable for spanners since they don't have
a parent even when added to a score. This commit adds a missing
implementation of Spanner::triggerLayoutAll() that takes this into
account.
- Remove disabled and largely outdated continuous view layout code
- Remove declarations of functions which have no definition
- Remove unused global libmscore variables
- Remove some excessive forward declarations
- tick names a position on the time axis
- tick is always a Fraction()
- only Measure() and Segment() (and Tuplet?) have a tick value
- tick() for an generic element return only a sensible value if isMeasure() or isSegment() or isSegment(parent())
- "ticks" names a duration stored in a Fraction()
- the tick value for an Segment is relative to its measure
- rename "duration" to "ticks"
- rename afrac() to tick()
- rename rfrac() to rtick()
- rename some variables, changing "fraction" into "tick"
(example: actualFraction() into actualTicks())
- Lyrics ticks are written as Fraction, on read if xmlreader sees a "/" it reads a fraction
else midi ticks for backwards compatibility
This commit adds:
- ScoreElement::propertyId for obtaining property ID by its XML name
within the context of the respective element
- ScoreElement::propertyUserValue to obtain values of the properties
in a human-readable representation
Element::pos() and Element::ipos() unclear and error prone semantic led to 382b7d79d8.
SpannerSegment::pos2() and SpannerSegment::ipos2() are not good as well.
I didn't apply renaming because active work is in progress.
Those changes include:
- Add a possibility to write comments to MSCX files
- Add Element::findMeasureBase and constant version of Element::findMeasure
- Store index of the currently read measure in XmlReader. Correct behaviour of MeasureBase::index.
- Minor spanners-related additions to elements creation and conversion
