Member Function Documentation

AudioParameters StateHandler::audioParameters

(

)

const

Returns output audio parameters.

void StateHandler::audioParametersChanged ( const AudioParameters &  p )

signal

Emitted when audio parameters have changed.

Parameters

p	New audio parameters for output.

int StateHandler::bitrate

(

)

const

Returns current bitrate (in kbps)

void StateHandler::bitrateChanged ( int  bitrate )

signal

Emitted when bitrate has changed.

Parameters

bitrate

New bitrate (in kbps)

void StateHandler::bufferingProgress ( int  progress )

signal

This signal is emitted when the stream reader fills it's buffer. The argument progress indicates the current percentage of buffering completed.

void StateHandler::dispatch	(	qint64	elapsed,

	)

Sends information about playback progress.

Parameters

elapsed	Current time (in milliseconds).
bitrate	Current bitrate (in kbps).

void StateHandler::dispatch

(

const AudioParameters &

p

)

Sends information about audio parameters.

Parameters

p	Output audio patameters.

void StateHandler::dispatch

(

qint64

duration

)

Sends information about song length

Parameters

duration

track length in milliseconds

bool StateHandler::dispatch

(

const TrackInfo &

info

)

Sends track information.

(

Qmmp::State

state

)

Sends playback state.

void StateHandler::dispatchBuffer

(

int

percent

)

Sends buffering progress.

Parameters

percent

Indicates the current percentage of buffering completed.

qint64 StateHandler::duration

(

)

const

Returns duration in milliseconds

qint64 StateHandler::elapsed

(

)

const

Returns the current time (in milliseconds).

signal

Tracks elapesed time.

Parameters

time	New track position in milliseconds.

static StateHandler* StateHandler::instance ( )

static

Returns a pointer to the first created StateHandler instance.

void StateHandler::sendFinished

(

)
