Detailed Description

This class is used to represent a constraint. A constaint is used by a Container to compute the possition of the various symbol. It is a sort of memory for our pen, because drawing music is a little harder than drawing simple text.

void Constraint::applyKerning (  int  first, int  last, double  kerning )

Apply the kerning from measure first to last (including it) Warning this method is quite difficult in algorithm you should be aware that litte modification could lead you to big trouble. see spec for explainations

void Constraint::beginNewLine (  int  msindex, double  linebegin )

Call this method if you start a new line Parameters: ms  index the measure section index linebegin  the line beginnning

int Constraint::countMeasureSection (   )

Returns: the number of measure section Constraints

int Constraint::countWhiteSpace (  int  first, int  last )

This method count the number of white space from measure first to measure last this is usefulle for computing the kerning Parameters: first  : the first measure section index last  : the last measure section index (including this measure)

double Constraint::getBaseLine (   )

Deprecated: Returns: the base line of the current staff (wont work)

MeasureSectionConstraint * Constraint::getMeasureSectionConstraint (  int  index  )

Returns: the measure section constraint corresponding to the measure section of index i

YLinesConstraint * Constraint::getYLinesConstraints (  int  pageNumber  )

Returns: the current Y Lines Constraint Parameters: pageNumber  : The page Supporting the YLine Constraint

void Constraint::removeLastMeasureSectionConstraint (   )

remove the last mesureSectionConstraint this is used by the line when it oversize the page margin destroy not only the reference but also the object.

void Constraint::setBaseLine (  double  b  )

Deprecated:
