I have got an array of 30 buttons []. I have a variable buttonClicked. When I press the button how can I get the index and store the index number in the buttonClicked?
谢谢:)
JButton [] buttons = new JButton[30];
for(int i = 1; i <= 30; i++)
{
int btnNumber = (i > 10 && i <= 20) ? (31 - i) : i;
System.out.printf("i = %d, btnNumber = %d%n", i, btnNumber);
buttons[btnNumber - 1] = new JButton("label " + btnNumber);
//buttons[btnNumber - 1].setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
buttons[btnNumber - 1].setBorder(BorderFactory.createEtchedBorder());
buttons[btnNumber - 1].setOpaque(true);
buttons[btnNumber - 1].setBackground(Color.white);
//Puts the player 1 piece on button 1,3,5,7,9 and player 2 piece on button 2,4,6,8,10
if ((btnNumber - 1) < 10)
{
if (((btnNumber - 1) % 2) == 0)
{
buttons[btnNumber - 1].setIcon(piece1);
}
else
{
buttons[btnNumber - 1].setIcon(piece2);
}
}
centerPanel.add(buttons[btnNumber - 1]);
}
//下面是我试图做的,我知道是不正确的.
//Below is what I am attempting to do, I know is not correct.
public void move()
{
Move = dice.getDiceResult();
int buttonClicked = 0;
if(playerOneTurn =true)
{
buttonclicked + diceResult();
}
//修改了
public class MyActionListener implements ActionListener {
Dice dice;
private boolean playerOneTurn = true;
private boolean playerTwoTurn = false;
@Override
public void actionPerformed(ActionEvent e)
{
String num = e.getActionCommand();
int index = Integer.parseInt(num);
int move = dice.getDiceResult();
int positionLanding = 0;
if(playerOneTurn = true)
{
positionLanding = index + move;
positionLanding.setIcon("piece1");//how can I set the image Icon to this position?
}
}
}
推荐答案
buttons[i][j].putClientProperty("column", i);
buttons[i][j].putClientProperty("row", j);
buttons[i][j].addActionListener(new MyActionListener());
public class MyActionListener implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
JButton btn = (JButton) e.getSource();
System.out.println("clicked column " + btn.getClientProperty("column")
+ ", row " + btn.getClientProperty("row"));
}
