Field Documentation

void(* PPB_TouchInputEvent::AddTouchPoint)(PP_Resource touch_event, PP_TouchListType list, const struct PP_TouchPoint *point)

Adds a touch point to the touch event in the specified touch-list.

Parameters:

[in]	touch_event	A `PP_Resource` corresponding to a touch event.
[in]	list	The list to add the touch point to.
[in]	point	The point to add to the list.

PP_Resource(* PPB_TouchInputEvent::Create)(PP_Instance instance, PP_InputEvent_Type type, PP_TimeTicks time_stamp, uint32_t modifiers)

Creates a touch input event with the given parameters.

Normally you will get a touch event passed through the HandleInputEvent and will not need to create them, but some applications may want to create their own for internal use. The type must be one of the touch event types. This newly created touch input event does not have any touch point in any of the touch-point lists. AddTouchPoint should be called to add the touch-points.

Parameters:

[in]	instance	The instance for which this event occurred.
[in]	type	A `PP_InputEvent_Type` identifying the type of input event.
[in]	time_stamp	A `PP_TimeTicks` indicating the time when the event occurred.
[in]	modifiers	A bit field combination of the `PP_InputEvent_Modifier` flags.

Returns:: A PP_Resource containing the new touch input event.

struct PP_TouchPoint(* PPB_TouchInputEvent::GetTouchById)(PP_Resource resource, PP_TouchListType list, uint32_t touch_id) [read]

Returns the touch-point with the specified touch-id in the specified list.

Parameters:

[in]	resource	A `PP_Resource` corresponding to a touch event.
[in]	list	The list.
[in]	touch_id	The id of the touch-point.

Returns:: A PP_TouchPoint representing the touch-point.

struct PP_TouchPoint(* PPB_TouchInputEvent::GetTouchByIndex)(PP_Resource resource, PP_TouchListType list, uint32_t index) [read]

Returns the touch-point at the specified index from the specified list.

Parameters:

[in]	resource	A `PP_Resource` corresponding to a touch event.
[in]	list	The list.
[in]	index	The index.

Returns:: A PP_TouchPoint representing the touch-point.

uint32_t(* PPB_TouchInputEvent::GetTouchCount)(PP_Resource resource, PP_TouchListType list)

Returns the number of touch-points in the specified list.

Parameters:

[in]	resource	A `PP_Resource` corresponding to a touch event.
[in]	list	The list.

Returns:: The number of touch-points in the specified list.

struct PP_FloatPoint(* PPB_TouchInputEvent::GetTouchTiltById)(PP_Resource resource, PP_TouchListType list, uint32_t touch_id) [read]

Returns the touch-tilt with the specified touch-id in the specified list.

Parameters:

[in]	resource	A `PP_Resource` corresponding to a touch event.
[in]	list	The list.
[in]	touch_id	The id of the touch-point.

Returns:: A PP_FloatPoint representing the tilt of the touch-point.

struct PP_FloatPoint(* PPB_TouchInputEvent::GetTouchTiltByIndex)(PP_Resource resource, PP_TouchListType list, uint32_t index) [read]

Returns the touch-tilt with the specified index in the specified list.

Parameters:

[in]	resource	A `PP_Resource` corresponding to a touch event.
[in]	list	The list.
[in]	index	The index.

Returns:: A PP_FloatPoint representing the tilt of the touch-point.

PP_Bool(* PPB_TouchInputEvent::IsTouchInputEvent)(PP_Resource resource)

IsTouchInputEvent() determines if a resource is a touch event.

Parameters:

[in] resource A PP_Resource corresponding to an event.

Returns:: PP_TRUE if the given resource is a valid touch input event, otherwise PP_FALSE.
