Member Enumeration Documentation

anonymous enum

Enumerator:

EAknEnableSkin	Flag indicating that default skin parameters should be provided by UI controls created within the scope of this AppUi instance. This value (or binary combination with some other values) should be given as a parameter to `BaseConstructL` in case the application wants to enable default skin parameters for all the Avkon controls supporting them. Note: The value can be queried by using `AknsUtils::AvkonSkinEnabled()` from AknSkins.lib.
EAppOrientationPortrait
EAppOrientationLandscape
EAppOrientationAutomatic
EAknDisableHighlightAnimation
EAknEnableMSK
EAknExplicitStartupEffectCompletion

enum CAknAppUiBase::TAppUiOrientation

Enumerator:

EAppUiOrientationUnspecified	Use the default device screen rotation of the product for this application. This is the default rotation setting for an application, and it should be used by nearly all applications.
EAppUiOrientationPortrait	Use a portrait screen rotation for this application. This should only be used when an application specifically wants portrait rotation. The device will select an appropriate portrait rotation, if one is available.
EAppUiOrientationLandscape	Use a landscape screen rotation for this application. This should only be used when an application specifically wants landscape rotation. The device will select an appropriate landscape rotation, if one is available.
EAppUiOrientationAutomatic	Use the normal device screen rotation for this application. Both portrait and landscape screen rotations are possible. The application rotation follows device screen rotation.

Reimplemented in CAknAppUi, and CAknViewAppUi.

IMPORT_C void CAknAppUiBase::ConstructL

(

Reimplemented in CAknAppUi.

TInt CAknAppUiBase::EventForForegroundState	(	TBool	aPartialFg,
		TBool	aForeground
	)

Simply return KEikPartialForeground if aPartialFg == ETrue, otherwise if aForeground == ETrue then return EEventFocusGained else return EEventFocusLost.

Returns:: if aPartialFg then return KEikPartialForeground.

IMPORT_C CAknWsEventMonitor* CAknAppUiBase::EventMonitor

(

)

const

Returns the object which allows events to be spyed upon in addition to normal event handling.

Returns:: Pointer to window server event monitor object.

IMPORT_C void CAknAppUiBase::Exit

(

)

From CEikAppUi.

Closes the app UI.

TInt CAknAppUiBase::FindAppWgIdBelowMeL

Returns:: the window group ID of the application below this application.

virtual IMPORT_C void CAknAppUiBase::HandleApplicationSpecificEventL	(	TInt	aType,
		const TWsEvent &	aEvent
	)	`[protected, virtual]`

From CCoeAppUi.

Handles an application specific event.

Parameters:

	aType	The type of the event that occurred. This should be a unique identifier constant.
	aEvent	The window server event that occurred.

IMPORT_C void CAknAppUiBase::HandleForegroundEventL

(

TBool

aForeground

)

Handles changes in keyboard focus when an application switches to, or from, the foreground.

This function calls CEikAppUi::HandleForegroundEventL.

IMPORT_C void CAknAppUiBase::SetOrientationL

(

TAppUiOrientation

aOrientation

)

Sets the application screen orientation.
