Detailed Description

Class for alerting user in case of incoming call.

Class that plays selected ringtone or remains silent, depending on users selections.

Member Function Documentation

virtual qint64 RingtonePlayer::bytesAvailable ( ) const

inlinevirtual

virtual void RingtonePlayer::callStatusChanged ( quint32  aCallId, VoiceCallEngine::CallState  aState  )

virtual

Method that communicates changes in call state. From interface MCallStatusObserver.

Implements MVoiceCallEngine::MCallStatusObserver.

void RingtonePlayer::error ( int  aError, const QString &  aExplanation  )

signal

this is not method but signal ; if in error, get emit()ted

virtual void RingtonePlayer::finishedPlaying ( QAudio::State  aState )

virtualslot

Notify slot from actual player device

void RingtonePlayer::initInput ( )

private

initializes input and codec

virtual bool RingtonePlayer::isSequential ( ) const

inlineprotectedvirtual

virtual void RingtonePlayer::notify ( )

virtualslot

notify from audio output device

virtual bool RingtonePlayer::open ( OpenMode  mode )

protectedvirtual

method for opening QIODevice: sets the open mode that's about it.

virtual qint64 RingtonePlayer::readData ( char *  data, qint64  maxSize  )

protectedvirtual

From QIODevice: method that QAudioOutput class instance will use to read the actual audio data. Data comes from internal buffer and is inserted into buffer using insertAudioFrame.

Parameters

data	pointer to buffer where data will be written
maxSize	max data size available in buffer

Returns

number of bytes actually written into buffer

void RingtonePlayer::stop ( )

slot

method for stopping playback

void RingtonePlayer::timerEvent

(

QTimerEvent *

event

)

From QObject. Used for feeding ringtone data to audio device

virtual qint64 RingtonePlayer::writeData ( const char *  data, qint64  maxSize  )

protectedvirtual

Write-method of QIODevice - QIODevice here is used for feeding the player and data is actually written using insertAudioFrame method so implementation of this method is actually empty.

Parameters

data	that will not be written anywhere.
maxSize	max data size to be not written

Returns

always 0
