RxSPViewServices Class Reference

class RxSPViewServices : public RSessionBase

The xSP View API, which is used to bring a certain view in front and get tab-view information.

There is an issue with KErrServerTerminated error code sometimes returned by this API functions. This situation may arise when server object is terminated with the Phonebook process but clients outside the Phonebook are not informed and their handles remain open. A way to deal with this KErrServerTerminated error is to close the handle first by calling Close() and then reopen it by calling Open() or Activate() methods which do not require explicit Open() calls.

The following panic codes are possible in case the API is abused:

Panic category xSPViewActivator. These panics represent programming errors which are detected by the view activator service that activates a tab view. Possible panic codes for this category are: EBadDescriptorLength = 0 (descriptor length was illegal), EBadDescriptor = 1 (descriptor type was not correct; could not write to client side descriptor buffer).

Activate(TUint32, TInt)

IMPORT_C TInt	Activate	(	TUint32	aEComID,
			TInt	aOriginalViewID
		)

Triggers xSP extension view activation. Starts the Phonebook if it was not running already. Designed to be used by the xSP extension view activator. If the session was not open, this method will open one and close it afterwards. If the session was open, this method will not close it afterwards.

Parameters

TUint32 aEComID	xSP extension ECom implementation ID
TInt aOriginalViewID	view original / old ID

Activate(TUint32, TInt, TPtr8 &)

IMPORT_C TInt	Activate	(	TUint32	aEComID,
			TInt	aOriginalViewID,
			TPtr8 &	aParamBuf
		)

Parameters

TUint32 aEComID	xSP extension ECom implementation ID
TInt aOriginalViewID	view original / old ID
TPtr8 & aParamBuf	specifies which contact to show (see CPbk2ViewState.h or CPbkViewState.h for details)

Activate(TUint32, TInt, TPtr8 &, TRequestStatus &)

IMPORT_C void	Activate	(	TUint32	aEComID,
			TInt	aOriginalViewID,
			TPtr8 &	aParamBuf,
			TRequestStatus &	aStatus
		)

Triggers view activation asynchronously.

Parameters

TUint32 aEComID	xSP extension ECom implementation ID
TInt aOriginalViewID	view original / old ID
TPtr8 & aParamBuf	specifies which contact to show (see CPbk2ViewState.h or CPbkViewState.h for details)
TRequestStatus & aStatus	contains the status of the request on completion

ActivateL(TUint32, TInt, MVPbkContactLink *, TInt)

			TInt	aFocusedField
		)

Parameters
