    Detailed Description

    The base of all Uikon applications.

    CEikApplication builds on CApaApplication, providing a basis for applications working within the framework provided by Uikon. It also contains an interface to the resource file and the document object belonging to the application.

    Each Uikon application class is derived from CEikApplication. Application writers must provide at least an implementation of the pure virtual function CreateDocumentL().

    The application's resource file can be changed from the default by overriding ResourceFileName().

    Constructor & Destructor Documentation

    CEikApplication ( )


    Default constructor.

    The default constructor is empty, and there are no NewL() or NewLC() functions as Uikon applications are created automatically by the application DLL framework when applications are started.

    ~CEikApplication ( )



    Deletes any resources acquired by this CEikApplication during its construction phases.

    Member Function Documentation

    AppCaption ( )

    const TApaAppCaption &AppCaption()const [inline]

    Gets the caption for this application.

    Captions are displayed in the task list.

    Returns: Application caption.

    BitmapStoreName ( )

    IMPORT_C TFileNameBitmapStoreName()const [virtual]

    Gets the localized name of the bitmap file used by this application.

    By default, this file has an extension of .mbm and uses the same name as the application file in the same directory. Language variants are supported using BaflUtils::NearestLanguageFile().

    Returns: The name of the bitmap store for this application.

    Capability ( TDes8 & )

    IMPORT_C voidCapability(TDes8 &aInfo)const [virtual]

    Gets the application's capabilities.

    Application developers should not need to override this function.

    CreateDocumentL ( CApaProcess * )

    IMPORT_C CApaDocument *CreateDocumentL(CApaProcess *aProcess)[protected, virtual]

    Creates a new document.

    This function is called by the application DLL framework during application startup to create a new instance of the document associated with this application. This implementation of the function makes a record of the CApaProcess argument, and returns a document created by the un-parameterised, private, overload.

    EnsureCaptionIsLocalisedL ( const TDesC & )

    IMPORT_C voidEnsureCaptionIsLocalisedL(const TDesC &aLocalisableResourceFile)[protected]

    Calling this method will ensure that the application Caption has been localized. This is called at the start of applications override of CEikApplication's CreateDocumentL, when application needs to started in Critical phase of Start-Up.

    aLocalisableResourceFileLocation of the localized resource file

    GetDefaultDocumentFileName ( TFileName & )

    IMPORT_C voidGetDefaultDocumentFileName(TFileName &aDocumentName)const [virtual]

    Gets the default document name for this application.

    aDocumentNameOn return, contains the default document file name.

    NewAppServerL ( CApaAppServer *& )

    IMPORT_C voidNewAppServerL(CApaAppServer *&aAppServer)[protected, virtual]

    Virtual function called by the framework when the application has been launched as a server application. Applications that wish to be used as server applications must override this function to return their implementation of the server.

    Base class implementation of this function leaves with KErrNotSupported, to prevent non-server applications from being launched as server applications.

    aAppServerThe server pointer to be set.

    OpenIniFileLC ( RFs & )

    IMPORT_C CDictionaryStore *OpenIniFileLC(RFs &aFs)const [virtual]

    Opens the application's .ini file, if one exists.

    If a .ini file does not exist for this application, or if it is corrupt, this function creates one and opens that. .ini files are located on system drive, in the same directory as the application EXE.

    aFsFile server session to use.

    Returns: Pointer to the dictionary store for the .ini file.

    PreDocConstructL ( )

    IMPORT_C voidPreDocConstructL()[protected, virtual]

    Prepares for document creation.

    This function is called by the application DLL framework to complete construction and initialise the new application object. After this function has been called, the CEikApplication can create document objects. If there is a default resource file for this app, then it is added to the control environment.

    If this function leaves, this should be treated as if construction had failed, and the object should be destroyed by the caller.

    Process ( )

    CApaProcess *Process()const [inline]

    Gets the managing process.

    Returns: A pointer to the process object managing this application's documents.

    ResourceFileName ( )

    IMPORT_C TFileNameResourceFileName()const [virtual]

    Gets the localized name of the resource file used by this application.

    By default, this file has an extension of .rsc and uses the same name as the application file located in the same directory. Language variants are supported through BaflUtils::NearestLanguageFile().

    Returns: The name of the resource file. Used by PreDocConstructL().

    ResourceFileOffset ( )

    TInt ResourceFileOffset()const [inline]

    Gets the offset value defined for this application's default resource file.

    As the resource file offset can also be accessed through iResourceFileOffset, this function should not be needed by any apps.

    Returns: Offset of a resource file.

    SetToIniFileNameL ( TParse & )

    IMPORT_C voidSetToIniFileNameL(TParse &aParser)const

    Sets a supplied file name parser to contain the path of this application's .ini file.

    aParserA file name parser. On return, this contains the path of the application's ini file.
