Quasimodo Class Reference

This object is in charge of actually ringing the local bells (using QAudioOutput and a mixer algorithm) This is done within a separate thread, so that the timing of the bell-ringing won't be affected GUI operations. More...

Member Function Documentation

void DestroyTheBells ( )

slot

Should be called once at shutdown, since destroying the bells in the destructor causes more thread-warnings.

void RangLocalBells ( quint64  notesChord )

signal

Emitted when we've played some bell sounds.

This signal is connected to a slot in the main/GUI thread that will cause the little bell icon to vibrate, so that the user can visually see which bells are "ringing"

virtual qint64 readData ( char *  data, qint64  maxSize  )

protectedvirtual

Overridden to fill (data) with audio samples from our internal sound-mixing-engine.

Parameters

data	a buffer to fill with audio samples
maxSize	the number of bytes pointed to by (data)

Returns

the number of bytes actually written, or -1 on error.

void RingSomeBells ( quint64  notesChord, bool  localNotesOnly  )

slot

Causes a given bell-sound to be played.

Parameters

notesChord	a bit-chord of CHOIR_NOTE_* values indicating which bell(s) to ring
localNotesOnly	If true, we'll only ring those bells in (notesChord) that are currently assigned to us.

void SetLocalNoteAssignments ( quint64  notesChord )

inlineslot

Tells Quasimodo which bells he should actually play.

Definition at line 39 of file Quasimodo.h.

void SetupTheBells ( )

slot

Should be called once at startup, since setting them up in the constructor causes thread-warnings.

virtual qint64 writeData ( const char *  , qint64  maxSize  )

inlineprotectedvirtual

This method is a no-op and should never be called.

It's only here because QIODevice requires it be implemented.
