Class CCHFEventMappingService

class CCHFEventMappingService : public CBase;

Description

Provides functionality to map key or pointer events to abstract events.

This class provides the functionality to map raw key or pointer events to CHF abstract events. The raw event mapping array that is provided is required to pass events to content handlers.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CCHFEventMappingService - Provides functionality to map key or pointer events to abstract events.

Members

Defined in CCHFEventMappingService:

• MapKeyEventL(RAbstractEventArray &,const TKeyEvent &,const TEventCode &)Maps a single raw key event to CHF abstract event(s).
• MapPointerEventL(RAbstractEventArray &,const TPointerEvent &)Maps a single raw pointer event to CHF abstract event(s).

Inherited from CBase:

• Delete(CBase *)Deletes the specified object.
• Extension_(TUint,TAny *&,TAny *)Extension function
• operator new(TUint)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TAny *)Initialises the object to binary zeroes.
• operator new(TUint,TLeave)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TLeave,TUint)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TUint)Allocates the object from the heap and then initialises its contents to binary z...
