= class Gdk::Event
Handling events from the window system
== Object Hierarchy
* Object
* GLib::Boxed
* Gdk::Event
== Class Methods
--- Gdk::Event.events_pending?
Checks if any events are ready to be processed for any display.
* Returns: true if any events are pending.
--- Gdk::Event.peek
If there is an event waiting in the event queue of some open display, returns a copy of it.
* Returns: a copy of the first Gdk::Event on some event queue, or nil if no events are in any queues.
--- Gdk::Event.get
Checks all open displays for a Gdk::Event to process,to be processed on, fetching events from the windowing system if necessary.
* Returns: the next Gdk::Event to be processed, or nil if no events are pending.
+ --- Gdk::Event.new(type)
+ Creates a new event of the given type. All fields are set to 0. ((*Since 2.2*))
+ * type: a ((<GdkEventType|Gdk::Event#GdkEventType>))
+ * Returns: a new Gdk::Event.
+
--- Gdk::Event.handler_set{|event| ... }
Sets the block to call to handle all events from GDK.
Note that GTK+ uses this to install its own event handler, so it is usually not useful for GTK+ applications. (Although an application can call this method then call Gtk.main_do_event to pass events to GTK+.)
* {|event| ... }: the block to call to handle events from GDK
* event: the event
* Returns: self
--- Gdk::Event.set_show_events
not yet
* Returns: self
--- Gdk::Event.setting_get

* Returns: self
--- Gdk::Event.show_events?

* Returns: self
== Instance Methods
--- put
Appends a copy of the self onto the front of the event queue for Gdk::EventAny#window 's display, or the default event queue if Gdk::Event#window is nil. See Gdk::Display#put_event.
* Returns: self
--- get_axis(axis_use)
Extract the axis value for a particular axis use from an event structure.
* axis_use : the axis use to look for (((<GdkAxisUse|Gdk::Device#GdkAxisUse>)))
* Returns: the value if the specified axis was found, otherwise nil
--- coords
Extract the event window relative x/y coordinates from an event.
* Returns: [x_win, y_win] if the event delivered event window coordinates, otherwise nil
* x_win: event window x coordinate
* y_win: event window y coordinate
--- root_coords
Extract the root window relative x/y coordinates from an event.
* Returns: [x_root, y_root] if the event delivered root window coordinates, otherwise nil
* x_root: root window x coordinate
* y_root: root window y coordinate
--- event_type
