LwKeyEvent

public LwKeyEvent(LwComponent target,
                  int id,
                  int code,
                  char ch,
                  int mask)

Constructs the event object with the specified source object, the event id, the key code associated with the key, the character that has been typed with the key and the mask that describes state of a keyboard.

Parameters:

target - the object where the event originated.

id - the specified event id.

code - the specified key code associated with the key.

ch - the specified key character.

mask - the specified key mask. Using the mask you can define for example status of "Ctrl", "Alt", "Shift" and so on keys.

public void reset(LwComponent target,
                  int id,
                  int code,
                  char ch,
                  int mask)

getKeyCode

public int getKeyCode()

Gets the key code associated with the key in the event.

Returns:

a key code.

getKeyChar

public char getKeyChar()

Gets the key character that has been typed.

Returns:

a key character.

getMask

public int getMask()

Gets the keyboard mask. The mask can be used to test if the "Ctrl", "Alt" and so on keys are pressed or not. Use java.awt.event.InputEvent key modifiers constants for the purpose.
