Static methods:

• public static bool get_angle (Event event1, Event event2, out double angle)
  If both events contain X/Y information, this function will return true and return in angle the relative angle from event1 to event2.
• public static bool get_center (Event event1, Event event2, out double x, out double y)
  If both events contain X/Y information, the center of both coordinates will be returned in x and y.
• public static bool get_distance (Event event1, Event event2, out double distance)
  If both events have X/Y information, the distance between both coordinates ( as in a straight line going from event1 to event2) will be returned.

Creation methods:

• protected Event ()

Methods:

• public unowned Event @ref ()
  Increase the ref count of this.
• public bool get_axes (out unowned double[] axes)
  Extracts all axis values from an event.
• public bool get_axis (AxisUse axis_use, out double value)
  Extract the axis value for a particular axis use from an event structure.
• public unowned Device? get_device ()
  Returns the device of an event.
• public unowned DeviceTool? get_device_tool ()
  If the event was generated by a device that supports different tools (eg.
• public unowned Display? get_display ()
  Retrieves the Display associated to the this.
• public unowned EventSequence get_event_sequence ()
  If this is a touch event, returns the EventSequence to which the event belongs.
• public EventType get_event_type ()
  Retrieves the type of the event.
• public TimeCoord[]? get_history ()
  Retrieves the history of the this, as a list of time and coordinates.
• public ModifierType get_modifier_state ()
  Returns the modifier state field of an event.
• public bool get_pointer_emulated ()
  Returns whether this event is an 'emulated' pointer event (typically from a touch event), as opposed to a real one.
• public bool get_position (out double x, out double y)
  Extract the event surface relative x/y coordinates from an event.
• public unowned Seat? get_seat ()
  Returns the seat that originated the event.
• public unowned Surface get_surface ()
  Extracts the Surface associated with an event.
• public uint32 get_time ()
  Returns the time stamp from this, if there is one; otherwise returns CURRENT_TIME.
• public bool triggers_context_menu ()
  This function returns whether a Event should trigger a context menu, according to platform conventions.
• public void unref ()
  Decrease the ref count of this, and free it if the last reference is dropped.
