public final class EventType
extends org.freedesktop.bindings.Constant
```
The type of a low-level Event received. Although an Event is delivered as a parameter of many signals (the "event" signals, in fact), in general you will rarely need to make use of their information.
WARNING Many of these constants are clearly internal. There's a strong argument to be made that some or all of these should not be publicly visible.
TODO Most of these descriptions are terribly sparse and copied from the underlying documentation. Ordinarily we wouldn't do that, but with any luck you'll not need to be using these classes directly. If anyone has further information on the detailed significance of these constants, please contribute improvements to this class.
This is principally used to discriminate what kind of concrete Event subclass to create. Note that we are in GDK here; These events refer to the low level constructs delivered to the GdkWindows that underlie Widgets.

- Field Detail
  - BUTTON_PRESS
```
public static final EventType BUTTON_PRESS
```
    A mouse button has been pressed. As you would expect, an Event having this EventType will be a EventButton.
  - BUTTON_PRESS_DOUBLE
```
public static final EventType BUTTON_PRESS_DOUBLE
```
    A mouse button has been double clicked. Each click should also have generated a BUTTON_PRESS event; regardless this will be handled in higher level semantics.
    Note that this is the constant GDK_2BUTTON_PRESS in the underlying library; we had to rename it slightly for translation into a legal Java identifier.
  - BUTTON_PRESS_TRIPLE
```
public static final EventType BUTTON_PRESS_TRIPLE
```
    A mouse button has been clicked three times in a brief period. You would probably see this generated from the sequence:
    - click (BUTTON_PRESS emitted),
    - click (BUTTON_PRESS then BUTTON_PRESS_DOUBLE emitted),
    - click (BUTTON_PRESS then BUTTON_PRESS_TRIPLE emitted).
    Your results may vary, however, depending on what else might be intercepting events along the way.
    Note that this is the constant GDK_3BUTTON_PRESS in the underlying library; we had to rename it slightly for translation into a legal Java identifier.
  - BUTTON_RELEASE
```
public static final EventType BUTTON_RELEASE
```
    A previously pressed mouse button has been released. This EventType will be found in a EventButton Event.
  - CLIENT_EVENT
```
public static final EventType CLIENT_EVENT
```
    A message has been received from another application (TODO meaning what?).
  - CONFIGURE
```
public static final EventType CONFIGURE
```
    The size, position, or stacking order of a Window has been changed. Apparently GTK discards these events for child Windows, but then you won't notice this because you're not using these constants directly anyway, right?
  - DELETE
```
public static final EventType DELETE
```
    The top level Window should be hidden or destroyed, presumably due to the user having clicked the close window button presented in the window manager's decorations.
  - DESTROY
```
public static final EventType DESTROY
```
    The Window has been destroyed.
  - DRAG_ENTER
```
public static final EventType DRAG_ENTER
```
    The pointer has entered the Window during a drag operation.
  - DRAG_LEAVE
```
public static final EventType DRAG_LEAVE
```
    The pointer has left the Window during a drag operation.
  - DRAG_MOTION
```
public static final EventType DRAG_MOTION
```
    The pointer has moved within the Window during a drag operation (why would you ever care?).
  - DRAG_STATUS
```
public static final EventType DRAG_STATUS
```
    The status of a drag operation initiated by this Window has changed (TODO to?).
  - DROP_FINISHED
```
public static final EventType DROP_FINISHED
```
    The drop operation initiated by the Window has been completed.
  - DROP_START
```
public static final EventType DROP_START
```
    A drop operation onto this Window has started.
  - ENTER_NOTIFY
```
public static final EventType ENTER_NOTIFY
```
    The pointer has entered a Window. This corresponds to EventCrossing.
  - EXPOSE
```
public static final EventType EXPOSE
```
    Part or all of the Window needs to be redrawn due to its having become visible.
  - FOCUS_CHANGE
```
public static final EventType FOCUS_CHANGE
```
    The keyboard focus has entered or left the Window.
  - KEY_PRESS
```
public static final EventType KEY_PRESS
```
    A key has been pressed.
  - KEY_RELEASE
```
public static final EventType KEY_RELEASE
```
    A key has been released
  - LEAVE_NOTIFY
```
public static final EventType LEAVE_NOTIFY
```
    The pointer has left a Window. This corresponds to EventCrossing.
  - MAP
```
public static final EventType MAP
```
    The Window has been mapped to the screen.
  - MOTION_NOTIFY
```
public static final EventType MOTION_NOTIFY
```
    The pointer has moved.
  - NO_EXPOSE
```
public static final EventType NO_EXPOSE
```
    The source region was completely available when parts of a drawable were copied. "This is not very useful" says the underlying API documentation. Really!
  - PROPERTY_NOTIFY
```
public static final EventType PROPERTY_NOTIFY
```
    A low level [ie X-windows] property of the Window has been changed or removed.
  - PROXIMITY_IN
```
public static final EventType PROXIMITY_IN
```
    An input device has moved into contact with a sensing surface (e.g. a touchscreen or graphics tablet).
  - PROXIMITY_OUT
```
public static final EventType PROXIMITY_OUT
```
    An input device has moved out of contact with a sensing surface, whatever that actually means.
  - SCROLL
```
public static final EventType SCROLL
```
    The scroll wheel was turned.
  - SELECTION_CLEAR
```
public static final EventType SELECTION_CLEAR
```
    The application has been told that it no longer owns a selection.

  - WINDOW_STATE
```
public static final EventType WINDOW_STATE
```
    The state of a Window has changed.
