public class Event
extends java.lang.Object
```
Instances of this class provide a description of a particular event which occurred within SWT. The SWT untyped listener API uses these instances for all event dispatching.
Note: For a given event, only the fields which are appropriate will be filled in. The contents of the fields which are not used by the event are unspecified.

```
    the widget that issued the event
  - type
```
public int type
```
    the type of event, as defined by the event type constants in class SWT

```
    the index of the item where the event occurred
  - gc

  - x
```
public int x
```
    depending on the event type, the x offset of the bounding rectangle of the region that requires painting or the widget-relative, x coordinate of the pointer at the time the mouse button was pressed or released
  - y
```
public int y
```
    depending on the event type, the y offset of the bounding rectangle of the region that requires painting or the widget-relative, y coordinate of the pointer at the time the mouse button was pressed or released
  - width
```
public int width
```
    the width of the bounding rectangle of the region that requires painting
  - height
```
public int height
```
    the height of the bounding rectangle of the region that requires painting
  - count
```
public int count
```
    depending on the event type, the number of following paint events which are pending which may always be zero on some platforms or the number of lines or pages to scroll using the mouse wheel
  - time
```
public int time
```
    the time that the event occurred. NOTE: This field is an unsigned integer and should be AND'ed with 0xFFFFFFFFL so that it can be treated as a signed long.
  - button
```
public int button
```
    the button that was pressed or released; 1 for the first button, 2 for the second button, and 3 for the third button, etc.
  - character
```
public char character
```
    depending on the event, the character represented by the key that was typed. This is the final character that results after all modifiers have been applied. For example, when the user types Ctrl+A, the character value is 0x01 (ASCII SOH). It is important that applications do not attempt to modify the character value based on a stateMask (such as SWT.CTRL) or the resulting character will not be correct.
  - keyCode
```
public int keyCode
```
    depending on the event, the key code of the key that was typed, as defined by the key code constants in class SWT. When the character field of the event is ambiguous, this field contains the unaffected value of the original character. For example, typing Ctrl+M or Enter both result in the character '\r' but the keyCode field will also contain '\r' when Enter was typed and 'm' when Ctrl+M was typed.

  - doit
```
public boolean doit
```
    depending on the event, a flag indicating whether the operation should be allowed. Setting this field to false will cancel the operation.
  - data
