HandleControlStateChange(CCoeControl *, TCoeState)

TInt	HandleControlStateChange	(	CCoeControl *	aControl,
			TCoeState	aState
		)

This is implemented for getting notificatons when given control's state (i.e. visiblity or dimming status) has been changed. This way Tactile FW knows to disable or enable the feedback for that control again.

Parameters

CCoeControl * aControl	- Pointer to the control, which visiblity or dimming status has changed.
TCoeState aState	- Can be used for knowing if it was dimming or visibility status that changed.

LayoutChanged()

IMPORT_C void

LayoutChanged

(

)

This should be called by the application framework for informing that current layout has been changed. This way Tactile FW can disable all feedback areas in those layouts, where pen usage is not enabled (direct feedback is on UI controls' responsibility).

MopSupplyObject(TTypeUid)

TTypeUid::Ptr

MopSupplyObject

(

TTypeUid

aId

)

We have to implement this because it is pure virtual in MObjectProvider , but we always return TTypeUid::Null .

Parameters

TTypeUid aId

- Encapsulates the Uid that identifies the type of object required. Ignored in this class.

NewL()

IMPORT_C CTouchFeedbackAdaptation *

NewL

(

)

[static]

Instantiation method.

One should not attempt to build more than one instance in each application process.
