譬如
定义：
JButton []btn=new JButton[20];
block[n].addMouseListener(new MouseListener(){
@Override
public void mouseClicked(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mousePressed(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseReleased(MouseEvent e) {
// TODO Auto-generated method stub
}
});
请问怎么通过点击鼠标获得n
鼠标按下但还没有释放，就会执行pressed。按下并且释放后才会执行click。。所以按下又释放后。会执行这两个。但pressed先执行。
mouseClicked：点击鼠标响应事件
mousePressed：鼠标按下时响应事件
class Test {
public static int SearchButtonIndex(Object[] buttons, Object button) {
if (buttons.length == 0 || buttons == null) {
return -1;
}
for (int i = 0; i < buttons.length; i++) {
if (buttons[i].equals(button)) {
return i;
}
}
return -1;
}
public static void main(String[] args) {
JFrame frame = new JFrame();
final JButton[] buttons = new JButton[20];
frame.setLayout(new GridLayout(4, 5));
for (int i = 0; i < 20; i++) {
buttons[i] = new JButton(i + "");
buttons[i].addMouseListener(new MouseListener() {
public void mouseClicked(MouseEvent e) {
