Member Functions Documentation

MrpoBalanceChange(TInt, TInt)

void	MrpoBalanceChange	(	TInt	aLeftPercentage,
			TInt	aRightPercentage
		)	[pure virtual]

Called when balance setting changes. This may be caused by other applications.

Since: S60 3.2 Left speaker volume percentage. This can be any value from zero to 100. Zero value means left speaker is muted.

Parameters

TInt aLeftPercentage
TInt aRightPercentage	Right speaker volume percentage. This can be any value from zero to 100. Zero value means right speaker is muted.

MrpoMuteChange(TBool)

void

MrpoMuteChange

(

TBool

aMute

)

[pure virtual]

Called when mute setting changes. This may be caused by other applications.

Since: S60 3.2

Parameters

TBool aMute

ETrue indicates audio is muted.

MrpoStateChange(TPlayerState, TInt)

void	MrpoStateChange	(	TPlayerState	aState,
			TInt	aError
		)	[pure virtual]

Radio state changed. This event is asynchronous and is received after a call to CRadioPlayerUtility::Play and CRadioPlayerUtility::Stop . This event is also generated when the radio is disrupted due to an error.

If the radio is disrupted due to an error, appropriate error code will be sent. The following are the most common error codes: KErrDied when radio is pre-empted by another application with higher priority, KErrHardwareNotAvailable when tuner is forced off (e.g. when FM transmitter is turned on).

Since: S60 3.2

Parameters

TPlayerState aState	Radio player state
TInt aError	A standard system error code, only used when aState is ERadioPlayerIdle

MrpoVolumeChange(TInt)

void

MrpoVolumeChange

(

TInt

aVolume

)

[pure virtual]

Called when volume changes. This may be caused by other applications.

Since: S60 3.2

Parameters

TInt aVolume

Current volume.
