Member Functions Documentation

AddObserverL(const MCCEDtmfObserver &)

void

AddObserverL

(

const MCCEDtmfObserver &

aObserver

)

[pure virtual]

Adds a new observer for MCCEDtmfInterface object.

leave: system error if observer adding fails

Parameters

const MCCEDtmfObserver & aObserver

Observer

CancelDtmfStringSending()

void

CancelDtmfStringSending

(

)

[pure virtual]

Cancels the ongoing DTMF tones string sending

Since: S60 3.2

ContinueStringSending(const TBool)

TInt

ContinueStringSending

(

const TBool

aContinue

)

[pure virtual]

Continue or cancels the sending of a DTMF string when it was stopped by the use of 'w' char in the string.

Since: S60 3.2

Parameters

const TBool aContinue

ETrue if sending of the DTMF string should continue, EFalse if the rest of the DTMF string is to be discarded

RemoveObserver(const MCCEDtmfObserver &)

TInt

RemoveObserver

(

const MCCEDtmfObserver &

aObserver

)

[pure virtual]

Remove an observer.

Since: S60 v3.2

Parameters

const MCCEDtmfObserver & aObserver

Observer

SendDtmfToneString(const TDesC &)

TInt

SendDtmfToneString

(

const TDesC &

aTones

)

[pure virtual]

Starts sending of DTMF tones string.

Since: S60 3.2

Parameters

const TDesC & aTones

The DTMF tones string to be send

SetObserver(const MCCEDtmfObserver &)

void

SetObserver

(

const MCCEDtmfObserver &

aObserver

)

[pure virtual]

Sets the observer for DTMF events. Given when dtmf interface is first requested. Client is not required to call this. TODO: remove this method and used Addobserver instead!

Since: S60 3.2

Parameters

const MCCEDtmfObserver & aObserver

Reference to observer interface

StartDtmfTone(const TChar)

TInt

StartDtmfTone

(

const TChar

aTone

)

[pure virtual]

Starts the transmission of a single DTMF tone across a connected and active voice call.

Since: S60 3.2

Parameters

const TChar aTone

The DTMF tone to be send

StopDtmfTone()

TInt

StopDtmfTone

(

)

[pure virtual]

Stops the transmission of a single DTMF tone, which had previously been started by use of the StartDTMFTone function member, across a connected and active voice call.

Since: S60 3.2
