Java 2 ME GameCanvas -- How to receive all keyPressed events?
Hello
I'm writing simple j2me calculator. using GameCanvas class as a basis of my interface. I need to handle both numpad key events and game-relaited events (such as UP, DOWN, FIRE, etc) for moving my cursor. The problem is that neither emulator, nor my Sony Ericsson doesn't receives some numpad and game-relaited events. For example, I get SOFT1, SEND, 2, 4, ASTERISK key pressed events, but don't receive 1, 3, LEFT, RIGH, UP, DOWN, FIRE events.class CalculatorCanvas extends GameCanvas
{
public CalculatorCanvas() throws java.io.IOException
{
super(true);
setFullScreenMode(true);
cursor = new Sprite(Image.createImage("/cursor.png"));
}
public void paint(Graphics g)
{
g.setColor(0);
g.fillRect(0, 0, getWidth(), getHeight());
cursor.paint(g);
}
protected void keyPressed(int keyCode)
{
System.out.println("keyPressed: " + get开发者_JAVA技巧KeyName(key));
if (keyCode == getKeyCode(RIGHT))
cursor.move(STEP, 0);
if (key == getKeyCode(LEFT))
cursor.move(-STEP, 0);
/*...*/
repaint();
}
private final int STEP = 3;
private Sprite cursor;
}
How can I receive all this events?
Thanks in advancePS I've found that Canvas (base class for GameCanvas) reseives all this events, but I have to use GameCanvas
check javadoc for GameCanvas constructor. You should call it with "false" !
