Detailed Description

Playable instances of music elements.

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

    CAPlayable class represents a base class for all the music elements which are
    playable (timeLength property is greater than 0). It also adds other properties
    like the music length (whole, half, quarter etc.), number of dots and instead
    of contexts, playable elements voices for their parent objects.

    Notes and rests inherit this class.

Constructor & Destructor Documentation

CAPlayable::CAPlayable	(	CAPlayableLength	length,
		CAVoice *	voice,
		int	timeStart,
		int	timeLength = `-1`
	)

Creates a new playable element with playable length length, voice, timeStart and number of dots dotted.

References calculateTimeLength(), setPlayableLength(), setTuplet(), and setVoice().

Here is the call graph for this function:

CAPlayable::~CAPlayable ( ) [virtual]

Destroys the playable element.

The element is removed from any voice, if part of.

Note:: Non-playable signs are not shifted back when removing the element from the voice.
