Static methods:

• public static unowned Event get ()
  Checks all open displays for a Event to process,to be processed on, fetching events from the windowing system if necessary. See get_event.
• public static void handler_set (owned EventFunc func)
  Sets the function to call to handle all events from GDK.
• public static unowned Event peek ()
  If there is an event waiting in the event queue of some open display, returns a copy of it. See peek_event.
• public static void request_motions (EventMotion event)
  Request more motion notifies if event is a motion notify hint event. This function should be used instead of get_pointer to request further motion notifies, because it also works for extension events where motion notifies are provided for devices other than the core pointer. Coordinate extraction, processing and requesting more motion events from a MOTION_NOTIFY event usually works like this:
• public static bool send_client_message_for_display (Display display, Event event, NativeWindow winid)

Creation methods:

• public Event (EventType type)
  Creates a new event of the given type. All fields are set to 0.

Methods:

• public Event copy ()
  Copies a Event, copying or incrementing the reference count of the resources associated with it (e.g. Window's and strings).
• public bool get_axis (AxisUse axis_use, out double value)
  Extract the axis value for a particular axis use from an event structure.
• public bool get_coords (out double x_win, out double y_win)
  Extract the event window relative x/y coordinates from an event.
• public bool get_root_coords (out double x_root, out double y_root)
  Extract the root window relative x/y coordinates from an event.
• public weak Screen get_screen ()
  Returns the screen for the event. The screen is typically the screen for event->any.window, but for events such as mouse events, it is the screen where the pointer was when the event occurs - that is, the screen which has the root window to which event->motion.x_root and event->motion.y_root are relative.
• public bool get_state (out ModifierType state)
  If the event contains a "state" field, puts that field in state. Otherwise stores an empty state (0). Returns true if there was a state field in the event. event may be null, in which case it's treated as if the event had no state field.
• public uint32 get_time ()
  Returns the time stamp from event, if there is one; otherwise returns CURRENT_TIME. If event is null, returns CURRENT_TIME.
• public void put ()
  Appends a copy of the given event onto the front of the event queue for event->any.window's display, or the default event queue if event->any.window is null. See put_event.
• public bool send_client_message (NativeWindow winid)
  Sends an X ClientMessage event to a given window (which must be on the default Display.) This could be used for communicating between different applications, though the amount of data is limited to 20 bytes.
• public void send_clientmessage_toall ()
  Sends an X ClientMessage event to all toplevel windows on the default Screen.
• public void set_screen (Screen screen)
  Sets the screen for event to screen. The event must have been allocated by GTK+, for instance, by copy.
