Detailed Description

Ritardando and Accellerando marks.

Licensed under the GNU GENERAL PUBLIC LICENSE. See LICENSE.GPL for details.

Relative tempo marks.

Ritardando starts with the current tempo and linearily decreases the tempo to the final tempo. The original tempo is restored after the ritardando is finished.

Accellerando does the opposite.

Member Function Documentation

CARitardando * CARitardando::clone ( CAMusElement * elt = 0 )

virtual

Reimplemented from CAMark.

References CARitardando(), finalTempo(), CAMusElement::isPlayable(), ritardandoType(), and CAMusElement::timeLength().

Here is the call graph for this function:

int CARitardando::compare ( CAMusElement * elt )

virtual

Compares the music element with the given elt and returns number of differences in their properties. Returns 0, if the music elements are exact; -1 if the music element type differs; otherwise number greater than 0.

This method is usually used when opening a score document where music elements are written in various voices (eg. barlines), but are eventually merged and written only once per staff.

Reimplemented from CAMark.
