Constructor Detail

### KeyCodeEvent

    public KeyCodeEvent()

Method Detail

### isArrow

    public static boolean isArrow(int keyCode)

  Does the key code represent an arrow key?

  Parameters:
    `keyCode` - the key code
  Returns:
    if it is an arrow key code

### getNativeKeyCode

    public int getNativeKeyCode()

  Gets the native key code. These key codes are enumerated in the `KeyCodes` class.

  Returns:
    the key code

### isDownArrow

    public boolean isDownArrow()

  Is this a key down arrow?

  Returns:
    whether this is a down arrow key event

### isLeftArrow

    public boolean isLeftArrow()

  Is this a left arrow?

  Returns:
    whether this is a left arrow key event

### isRightArrow

    public boolean isRightArrow()

  Is this a right arrow?

  Returns:
    whether this is a right arrow key event

### isUpArrow

    public boolean isUpArrow()

  Is this a up arrow?

  Returns:
    whether this is a right arrow key event

### toDebugString

    public java.lang.String toDebugString()

  Description copied from class: `GwtEvent`
  This is a method used primarily for debugging. It gives a string representation of the event details. This does not override the toString method because the compiler cannot always optimize toString out correctly. Event types should override as desired.

  Overrides:
    `toDebugString` in class `GwtEvent<H extends EventHandler>`
  Returns:
    a string representing the event's specifics.
