keyListener isn't working for me
in an applet i made with a KeyListener and a MouseListener,
my keyListener will not respond to keys pressed.
the mouseListener works fine.
the keyTyped, keyPressed, and keyReleased methods just won't get called.
can someone please find my mistake?
publicclass Cursorextends JAppletimplements MouseListener, KeyListener{
BooleanJLabel[][] grid =new BooleanJLabel[5][5];
Icon backgroundIcon =new ImageIcon(Cursor.class.getResource("images/background.gif"));
Icon cursorIcon =new ImageIcon(Cursor.class.getResource("images/cursor.gif"));
Icon exclamationIcon =new ImageIcon(Cursor.class.getResource("images/exclamation.gif"));
Icon bothIcon =new ImageIcon(Cursor.class.getResource("images/both.gif"));
int cursorX = 0;
int cursorY = 0;
publicvoid init(){
setSize(250, 250);
setLayout(new GridLayout(5,5));
for(int countY = 0; countY <5; countY++){
for(int countX = 0; countX <5; countX++){
BooleanJLabel background =new BooleanJLabel(backgroundIcon);
background.addMouseListener(this);
grid[countY][countX] = background;
add(background);
}
}
addKeyListener(this);
}
publicvoid mouseClicked(MouseEvent m){
}
publicvoid mouseEntered(MouseEvent m){
int x = ((JLabel)m.getSource()).getX()/50;
int y = ((JLabel)m.getSource()).getY()/50;
cursorX = x;
cursorY = y;
if(grid[cursorY][cursorX].isActivated()){
grid[cursorY][cursorX].setIcon(bothIcon);
}else{
grid[cursorY][cursorX].setIcon(cursorIcon);
}
}
publicvoid mouseExited(MouseEvent m){
int x = ((JLabel)m.getSource()).getX()/50;
int y = ((JLabel)m.getSource()).getY()/50;
if(grid[cursorY][cursorX].isActivated()){
grid[y][x].setIcon(exclamationIcon);
}else{
grid[y][x].setIcon(backgroundIcon);
}
}
publicvoid mousePressed(MouseEvent m){
}
publicvoid mouseReleased(MouseEvent m){
if(m.getButton()==MouseEvent.BUTTON1){
grid[cursorY][cursorX].switchActivated();
if(grid[cursorY][cursorX].isActivated()){
grid[cursorY][cursorX].setIcon(bothIcon);
}else{
grid[cursorY][cursorX].setIcon(cursorIcon);
}
}
}
publicvoid keyPressed(KeyEvent k){
}
publicvoid keyReleased(KeyEvent k){
}
publicvoid keyTyped(KeyEvent k){
grid[4][4].setIcon(exclamationIcon);
}
}
