Member Function Documentation

audioParameters()

AudioParameters audioParameters

(

)

const

Returns output audio parameters.

audioParametersChanged

void audioParametersChanged ( const AudioParameters &  p )

signal

Emitted when audio parameters have changed.

Parameters

p	New audio parameters for output.

bitrate()

int bitrate

(

)

const

Returns current bitrate (in kbps)

bitrateChanged

void bitrateChanged ( int  bitrate )

signal

Emitted when bitrate has changed.

Parameters

bitrate

New bitrate (in kbps)

bufferingProgress

)

Sends information about audio parameters.

Parameters

p	Output audio patameters.

dispatch() [2/6]

void dispatch

(

const QHash< QString, QString > &

info

)

Sends stream information info

dispatch() [3/6]

bool dispatch

(

const TrackInfo &

info

)

Sends track information.

Parameters

info	track information.

dispatch() [4/6]

void dispatch

(

qint64

duration

)

Sends information about song length

Parameters

dispatch() [6/6]

void dispatch

(

Qmmp::State

state

)

Sends playback state.

dispatchBuffer()

void dispatchBuffer

(

int

percent

)

elapsedChanged

void elapsedChanged ( qint64  time )

signal

Tracks elapesed time.

Parameters

time	New track position in milliseconds.

instance()

static StateHandler* instance ( )

static

Returns a pointer to the first created StateHandler instance.

sendFinished()
