Description

Gets the scancode.

Return value

TInt The scancode.

IMPORT_C TInt Modifiers() const;

Description

Gets the modifiers.

TInt The modifiers.

Panic codes

EUSER 34 If the event does not represent a modifier key being pressed, i.e. if the event type is not TRawEvent::EUpdateModifiers

IMPORT_C TPoint3D Pos3D() const;

Description

Gets the Cartesian coordinates of the 3D pointer end that is closer to the screen.

Return value

TPoint3D The Cartesian coordinates of the point defined by the end of the 3D pointing device that is closer to the screen.

IMPORT_C TAngle3D Tilt() const;

Description

Gets the angular spherical polar coordinates of the 3D pointer end that is closer to the screen.

Return value

TAngle3D The angular spherical polar coordinates of the point defined by the end of the 3D pointing device that is closer to the screen.

IMPORT_C TInt Rotation() const;

Description

Gets the rotation angle of 3D pointing device.

Some 3D pointing devices support information regarding the angle formed between the physical and magnetical poles, as obtaining when rotating the pen along its main axis.

Return value

TInt The rotation angle of the 3D pointing device.

inline TUint Ticks() const;

Description

Gets the tick count value associated with the event.

Note that the interval between tick counts is hardware dependent.

Return value

TUint The tick count value

Return value

TBool A Boolean indicating which end of the pointing device is closer to the screen.

inline void SetTip(TBool aTip);

Description

Sets the information on which end of the pointing device is closer to the screen

Parameters

TBool aTip A Boolean indicating which end of the pointing device is closer to the screen.

Parameters

TType aType The event type. TInt aAlpha The rotation angle.

TType

Description

Defines the event type.

ENone Represents an uninitialised event object. EPointerMove A pointer device (e.g. a pen) has moved. Only changes in Cartesian coordinates are tracked. EPointerSwitchOn A switch on event caused by a screen tap using a pointer device. EKeyDown Represents a keyboard key down event. EKeyUp Represents a keyboard key up event. ERedraw Represents a redraw event. Typically generated in an emulator environment in response to a host OS redraw event. ESwitchOn Represents a device switch on event. EActive EInactive EUpdateModifiers Represents a modifier key being pressed. EButton1Down Represents a button down event. This is typically used to represent a pointing device coming into contact with a touch sensitive screen. EButton1Up Represents a button up event. This is typically used to represent a pointing device being lifted away from a touch sensitive screen. EButton2Down Represents a button down event. This is typically used to represent a pointing device coming into contact with a touch sensitive screen. EButton2Up Represents a button up event. This is typically used to represent a pointing device being lifted away from a touch sensitive screen. EButton3Down Represents a button down event. This is typically used to represent a pointing device coming into contact with a touch sensitive screen. EButton3Up Represents a button up event. This is typically used to represent a pointing device being lifted away from a touch sensitive screen. ESwitchOff Represents a device switch off event. EKeyRepeat Represents a key being continually pressed event. ECaseOpen Represents a case open event. The meaning of a case is hardware specific. ECaseClose Represents a case close event. The meaning of a case is hardware specific.
