Member Functions Documentation

BaseConstructL(TInt, TInt)

IMPORT_C void	BaseConstructL	(	TInt	aViewRscId,
			TInt	aTitleRscId
		)

Symbian OS default constructor. Call this from sub classes.

Parameters

TInt aViewRscId
TInt aTitleRscId

CheckMiddleSoftkeyLabelL()

void

CheckMiddleSoftkeyLabelL

(

)

Checks if the MSK label needs to be adjusted.

ConstructContainerL()

void

ConstructContainerL

(

)

[private]

Constructs container for this view.

DoActivateL(const TVwsViewId &, TUid, const TDesC8 &)

IMPORT_C void	DoActivateL	(	const TVwsViewId &	aPrevViewId,
			TUid	aCustomMessageId,
			const TDesC8 &	aCustomMessage
		)	[protected, virtual]

See base class.

Parameters

const TVwsViewId & aPrevViewId
TUid aCustomMessageId
const TDesC8 & aCustomMessage

DoDeactivate()

IMPORT_C void

DoDeactivate

(

)

[protected, virtual]

See base class.

DynInitMenuPaneL(TInt, CEikMenuPane *)

IMPORT_C void	DynInitMenuPaneL	(	TInt	aResourceId,
			CEikMenuPane *	aMenuPane
		)	[protected]

See base class.

Parameters

TInt aResourceId
CEikMenuPane * aMenuPane

GetHelpContext(TCoeHelpContext &)

IMPORT_C void

GetHelpContext

(

TCoeHelpContext &

aContext

)

[virtual]

Provides help context. This should be implemented by CGSParentPlugin sub class in case help is needed. Normally this is defined in CCoeControl derived class but since all parent plugin implementations have only CGSParentContainer class as the only CCoeControl derived class, and need still their own unique help contexts, this function is needed in view level class.

Parameters

TCoeHelpContext & aContext

HandleCommandL(TInt)

IMPORT_C void

HandleCommandL

(

TInt

aCommand

)

[protected, virtual]

See base class.

Parameters

TInt aCommand

HandlePluginLoaded(KGSPluginLoaderStatus)

IMPORT_C void

HandlePluginLoaded

(

KGSPluginLoaderStatus

aStatus

)

See base class.

Parameters

KGSPluginLoaderStatus aStatus

ListBoxType()

IMPORT_C TGSListboxTypes

ListBoxType

(

)

[virtual]

Defines the type of the used listbox visualising the child plugins. Classes deriving from CGSParentContainer can override this function to define the used type of the listbox. Otherwise default value EGSListBoxTypeSingleLarge is used.

OpenLocalizedResourceFileL(const TDesC &, RConeResourceLoader &)

IMPORT_C void	OpenLocalizedResourceFileL	(	const TDesC &	aResourceFileName,
			RConeResourceLoader &	aResourceLoader
		)

Opens the nearest localized resourcefile using aResourceLoader. aResourceLoader should be opened only once before closing it. Otherwise it will raise a panic. Therefore it is better to have multiple resource loaders. Uses KDC_RESOURCE_FILES_DIR.

Parameters

const TDesC & aResourceFileName	Drive and name of resource file in format <path>:<rsc_file_name>
RConeResourceLoader & aResourceLoader	Resource loader for the resource. The loader must not be opened allready or it will raise a panic. It is caller's responsibility to close the resource loader after using the resource.

OptionFlags()

IMPORT_C const TBitFlags &

OptionFlags

(

)

const [virtual]

Gets currently used option flags.

RemoveCommandFromMSK(TInt)

void

RemoveCommandFromMSK

(

TInt

aMskCommandId

)

[private]

Remove command from MSK.

Parameters

TInt aMskCommandId

ID of the command to be removed.

RequestPriority(CActive::TPriority)

void

RequestPriority

(

CActive::TPriority

aPriority

)

Attempts to change child plugin load priority on next RunL cycle. Use this if parent needs to change plugin loader priority. Normally when parent plugin view is opened, it is advisable to increase loader priority to get child plugins loaded faster.

Parameters

CActive::TPriority aPriority

Desired priority.

ResetSelectedItemIndex()

IMPORT_C void

ResetSelectedItemIndex

(

)

[virtual]

See base class.

SelectedPlugin()

IMPORT_C CGSPluginInterface *

SelectedPlugin

(

)

SetMiddleSoftKeyLabelL(const TInt, const TInt)

void	SetMiddleSoftKeyLabelL	(	const TInt	aResourceId,
			const TInt	aCommandId
		)

Adds given resource text as MSK to CBA. Use either this or SetMiddleSoftKeyLabelTextL in in case text is used deirectly instead of resource.

Since: S60 v3.1

Parameters

const TInt aResourceId	middle softkey label.
const TInt aCommandId	command that should be performed when MSK is pressed.

SetMiddleSoftKeyLabelTextL(const TPtr, const TInt)

void	SetMiddleSoftKeyLabelTextL	(	const TPtr	aMskLabel,
			const TInt	aCommandId
		)

Adds given text as MSK to CBA.

Since: S60 v3.1

Parameters

const TPtr aMskLabel	middle softkey label.
const TInt aCommandId	command that should be performed when MSK is pressed.

SetOptionFlags(TBitFlags &)

IMPORT_C void

SetOptionFlags

(

TBitFlags &

aOptionFlags

)

[virtual]

Defines custom options for parent plugin. Use TGSOptionFlagIndexes to enable a combination of bit flags.

Parameters

TBitFlags & aOptionFlags

Option combination created by combining binary option flags.

StartAsyncPluginLoadL()

void

StartAsyncPluginLoadL

(

)

[private]

Used in lazy loading. Starts loading the plugins.

(

CGSPluginInterface *

aPlugin

)

Parameters

CGSPluginInterface * aPlugin

UpdateView()

IMPORT_C void

(

)

[virtual]

Updates plugin's view. This can be used when child plugin's values are changed.
