/** 
 *  @var EventType NOTHING
 * A special code to indicate a null event.
 * 
 *  @var EventType DELETE
 * The window manager has requested that the toplevel window be
 * hidden or destroyed, usually when the user clicks on a special icon in the

 *  @var EventType BUTTON_PRESS
 * A mouse button has been pressed.
 * 
 *  @var EventType DOUBLE_BUTTON_PRESS
 * A mouse button has been double-clicked (clicked twice
 * within a short period of time). Note that each click also generates a
 * Gdk::BUTTON_PRESS event.
 * 
 *  @var EventType TRIPLE_BUTTON_PRESS
 * A mouse button has been clicked 3 times in a short period
 * of time. Note that each click also generates a Gdk::BUTTON_PRESS event.

 * 
 *  @var EventType FOCUS_CHANGE
 * The keyboard focus has entered or left the window.
 * 
 *  @var EventType CONFIGURE
 * The size, position or stacking order of the window has changed.
 * Note that GTK+ discards these events for Gdk::WINDOW_CHILD windows.

 * surface.
 * 
 *  @var EventType DRAG_ENTER
 * The mouse has entered the window while a drag is in progress.
 * 
 *  @var EventType DRAG_LEAVE
 * The mouse has left the window while a drag is in progress.
 * 
 *  @var EventType DRAG_MOTION
 * The mouse has moved in the window while a drag is in
 * progress.
 * 
 *  @var EventType DRAG_STATUS
 * The status of the drag operation initiated by the window
 * has changed.
 *

 * The window visibility status has changed.
 * 
 *  @var EventType SCROLL

 * for the possible window states.
 * 
 *  @var EventType SETTING
 * A setting has been modified.
 * 
 *  @var EventType OWNER_CHANGE
 * The owner of a selection has changed. This event type
 * was added in 2.6.
 * 
 *  @var EventType GRAB_BROKEN
 * A pointer or keyboard grab was broken. This event type
 * was added in 2.8.
 * 
 *  @var EventType DAMAGE
 * The content of the window has been changed. This event type
 * was added in 2.14.
 * 
 *  @var EventType TOUCH_BEGIN
 * A new touch event sequence has just started. This event
 * type was added in 3.4.
 * 
 *  @var EventType TOUCH_UPDATE
 * A touch event sequence has been updated. This event type
 * was added in 3.4.
 * 
 *  @var EventType TOUCH_END
 * A touch event sequence has finished. This event type

 * A touchpad swipe gesture event, the current state
 * is determined by its phase field. This event type was added in 3.18.
 * 
 *  @var EventType TOUCHPAD_PINCH
 * A touchpad pinch gesture event, the current state
 * is determined by its phase field. This event type was added in 3.18.
 * 
 *  @var EventType PAD_BUTTON_PRESS
 * A tablet pad button press event. This event type
 * was added in 3.22.
 * 
 *  @var EventType PAD_BUTTON_RELEASE
 * A tablet pad button release event. This event type
 * was added in 3.22.
 * 
 *  @var EventType PAD_RING
 * A tablet pad axis event from a "ring". This event type was
 * added in 3.22.
 * 
 *  @var EventType PAD_STRIP
 * A tablet pad axis event from a "strip". This event type was
 * added in 3.22.
 * 
 *  @var EventType PAD_GROUP_MODE
 * A tablet pad group mode change. This event type was
 * added in 3.22.
 * 
 *  @var EventType EVENT_LAST
 * Marks the end of the GdkEventType enumeration. Added in 2.18.
 * 
 *  @enum EventType
 * 
 * Specifies the type of the event.
 * 
 * Do not confuse these events with the signals that GTK+ widgets emit.
 * Although many of these events result in corresponding signals being emitted,
 * the events are often transformed or filtered along the way.
 * 
 * In some language bindings, the values Gdk::2BUTTON_PRESS and
 * Gdk::3BUTTON_PRESS would translate into something syntactically
 * invalid (eg `Gdk.EventType.2ButtonPress`, where a
 * symbol is not allowed to start with a number). In that case, the
 * aliases Gdk::DOUBLE_BUTTON_PRESS and Gdk::TRIPLE_BUTTON_PRESS can
 * be used instead.
