```
public class Event
extends 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.

  - widget
```
public Widget widget
```
    the widget that issued the event
  - type
```
public int type
```
    the type of event, as defined by the event type constants in class SWT
    
    See Also:
    
    SWT
  - detail
```
public int detail
```
    the event specific detail field, as defined by the detail constants in class SWT

  - item
```
public Widget item
```
    the item that the event occurred in (can be null)
  - index
```
public int index
```
    the index of the item where the event occurred
    
    Since:
    
    3.2
  - gc
```
public GC gc
```
    the graphics context to use when painting that is configured to use the colors, font and damaged region of the control. It is valid only during the paint and must not be disposed
  - 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 that are pending which may always be zero on some platforms, or the number of lines or pages to scroll using the mouse wheel, or the number of times the mouse has been clicked
  - 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.

    SWT
  - keyLocation
```
public int keyLocation
```
    depending on the event, the location of key specified by the keyCode or character. The possible values for this field are SWT.LEFT, SWT.RIGHT, SWT.KEYPAD, or SWT.NONE representing the main keyboard area.
    The location field can be used to differentiate key events that have the same key code and character but are generated by different keys in the keyboard. For example, a key down event with the key code equals to SWT.SHIFT can be generated by the left and the right shift keys in the keyboard. The location field can only be used to determine the location of the key code or character in the current event. It does not include information about the location of modifiers in state mask.
    
    Since:
    
    3.6
