= 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.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
    
    * 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
    
    * Returns: self
--- screen
    
    * Returns: self
--- set_screen
    
    * Returns: self
--- set_window
