CMnMapViewServiceBase Class Reference

class CMnMapViewServiceBase : public CMnServiceBase

Provider Application must derive its MapView service class from this one. This base implementation hides IPC communication details and provides native methods for accessing various map parameters, specified by client.

Provider Application must return pointer to instance of its class, derived from this class, in response to CAknAppService::CreateServiceL() call, if given parameter is KMnAppMapViewService.

This class defines handlers of particular requests from client as pure virtual methods, which derived class must implement. The parameters, which client application may specify in CMnMapView are accessible via other methods of this class. Provider Application must obey these parameters and use them as specified in CMnMapView .

See parent CMnServiceBase class documentation for other details.

AreaRadius()

IMPORT_C TReal

AreaRadius

(

)

Implementation has to obey this setting as long as this is within allowed range. If it is too low and cannot be used, the implementation must select lowest possible radius. If this value is KAutomaticRadius, it is considered not set.

BaseConstructL()

IMPORT_C void

BaseConstructL

(

)

[protected]

This method must be called from derived class' ConstructL to allow internal initialization of this class.

CleanSelectionResult()

CompleteSelectionRequest(TInt)

IMPORT_C void

CompleteSelectionRequest

(

TInt

aLandmarkIndex

)

Implementation must call this method to signal completion of Select From Map request. This override is used if one of not linked landmarks has been selected by user.

panic: "MnPanicServer"-KMnPanicArrayIndexOutOfBounds aLandmarkIndex is negative or greater than LandmarksToShow() .Count().

Parameters

TInt aLandmarkIndex

Index of not linked landmark containing information about user-selected location. As much information as possible shall be set.

CompleteSelectionRequest(TPosLmItemId, TInt)

IMPORT_C void	CompleteSelectionRequest	(	TPosLmItemId	aLandmarkId,
			TInt	aDbIndex
		)

Implementation must call this method to signal completion of Select From Map request. This override is used if one of linked landmarks, passed by client has been selected by user.

panic: "MnPanicServer"-KMnPanicArrayIndexOutOfBounds aDbIndex is negative or greater than LandmarksToShowDatabases() .Count().

Parameters

TPosLmItemId aLandmarkId	ID of landmark selected by user.
TInt aDbIndex	Index of database where landmark specified by aLandmarkId belongs to.

CompleteSelectionRequestL(const CPosLandmark &)

IMPORT_C void

CompleteSelectionRequestL

(

const CPosLandmark &
