32 Wireless Toolkit Basic Customization Guide • December 2003
Note – Virtual key codes are defined by the Abstract Window Toolkit in Java 2
Standard Edition. The definitions are found in the class
java.awt.event.KeyEvent at
http://java.sun.com/j2se/1.4/docs/api/java/awt/event/
KeyEvent.html
For example,
key.LEFT = VK_LEFT
More than one PC key may be assigned to a single button, using the form:
key.<button_name> = <list of virtual key codes>
where the virtual key codes are separated by spaces.
For example,
key.0 = VK_0 VK_NUMPAD0
Assigning a Game Action to a Button
The QwertyKeyboardHandler also allows the MIDP game actions to be mapped to
device buttons. You use a line of the form:
game.<function> = <button_name>
where function can be one of LEFT, RIGHT, UP, DOWN and SELECT and
button_name is the name of a button as shown in TABLE 2 on page 29.
The default settings are:
game.UP = UP
game.DOWN = DOWN
game.LEFT = LEFT
game.RIGHT = RIGHT
game.SELECT = SELECT
Specifying the Characters Generated by a Button Press
When using the QwertyKeyboardHandler, you can also specify the character
generated by a button press either alone or in combination with the Shift or Alt
buttons.
You use a line of the form:
keyboard.handler.qwerty.<button_name> = '<base character>' '<shift
character>' '<alternate character>'
where base character is the character the button normally generates, shift
character is the character used when the button is pressed at the same time as
Shift, and alternate character is the character generated when the button is
pressed at the same time as Alt.
