问题描述
我正在用Java创建一个简单的扫雷游戏。大小为9x9。
I'm creating a simple Minesweeper game in Java. Size 9x9.
我创建了一个 JPanels
数组和一个按钮数组;我将每个按钮添加到各自的 JPanel
中。然后我将 JPanels
添加到 JFrame
。
I create an array of JPanels
and an array of buttons; I add each button to its respective JPanel
. then i add the JPanels
to the JFrame
.
我如何区分动作事件的每个按钮?
How do i distinguish between each button on the action event?
以下是我的一些代码:
int gridx = 9;
int gridy = 9;
JButton[] buttons = new JButton[gridx*gridy];
JPanel[] jpanels = new JPanel[gridx*gridy];
public Minesweeper(){
super("Minesweeper");
setLayout(new GridLayout(9,9));
JPanel panel = new JPanel();
int i = 0;
for(i = 0; i<gridx*gridy; i++){
jpanels[i] = new JPanel();
buttons[i] = new JButton();
buttons[i].addActionListener(buttonEvent);
jpanels[i].setLayout(new GridLayout(1,1));
jpanels[i].add(buttons[i]);
add(jpanels[i]);
}
//buttons[67].setEnabled(false);
setSize(300,300);
setVisible(true);
}
我能想到的唯一方法是在按钮上添加文本因此:
The only way i can think about doing this is adding text to the button like so:
buttons[i] = new JButton(i);
然后调用 getActionCommand()
但我没有希望文本显示在按钮上。还有其他想法吗?
Then calling getActionCommand()
but i dont want text to show up on the button. Any other ideas?
推荐答案
您可以使用。
在您的循环中:
buttons[i].setActionCommand(i+"");
然后,当您返回 i
时,您使用 getActionCommand
Then you'll get i
back when you use getActionCommand
请注意,我确实在另一个答案的注释中提到要创建一个新类我的
我的扩展了JButton
,我认为这是一个更好,更完整的解决方案。但是,这可以很快完成工作。
Note I did mention in a comment on another answer that I would create a new class Mine
which extends JButton
which I believe to be a better and more complete solution. This however gets the job done rather quickly.
