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 String toDebugString()

Description copied from class: Event

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 Event<H extends EventHandler>

Returns:

a string representing the event's specifics.
