Detailed Description

This class handles mouse events.

Constructor & Destructor Documentation

pp::MouseInputEvent::MouseInputEvent ( const InputEvent &  event )

explicit

This constructor constructs a mouse input event object from the provided generic input event. If the given event is itself is_null() or is not a mouse input event, the mouse object will be is_null().

Parameters

event

An InputEvent.

pp::MouseInputEvent::MouseInputEvent	(	const InstanceHandle &	instance,
		PP_InputEvent_Type	type,
		PP_TimeTicks	time_stamp,
		uint32_t	modifiers,
		PP_InputEvent_MouseButton	mouse_button,
		const Point &	mouse_position,
		int32_t	click_count,
		const Point &	mouse_movement
	)

This constructor manually constructs a mouse event from the provided parameters.

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.
[in]	mouse_button	The button that changed for mouse down or up events. This value will be PP_EVENT_MOUSEBUTTON_NONE for mouse move, enter, and leave events.
[in]	mouse_position	A Point containing the x and y position of the mouse when the event occurred.
[in]	click_count@param[in]	mouse_movement The change in position of the mouse.

Member Function Documentation

PP_InputEvent_MouseButton pp::MouseInputEvent::GetButton

(

)

const

GetButton() returns the mouse position for a mouse input event.

Returns

The mouse button associated with mouse down and up events. This value will be PP_EVENT_MOUSEBUTTON_NONE for mouse move, enter, and leave events, and for all non-mouse events.

Point pp::MouseInputEvent::GetMovement

(

)

const

Returns the change in position of the mouse. When the mouse is locked, although the mouse position doesn't actually change, this function still provides movement information, which indicates what the change in position would be had the mouse not been locked.

Returns

The change in position of the mouse, relative to the previous position.

Point pp::MouseInputEvent::GetPosition

(

)

const

GetPosition() returns the pixel location of a mouse input event. When the mouse is locked, it returns the last known mouse position just as mouse lock was entered.

Returns

The point associated with the mouse event, relative to the upper- left of the instance receiving the event. These values can be negative for mouse drags. The return value will be (0, 0) for non-mouse events.
