问题描述
我有一个按钮执行很长的功能,我想在用户点击它之后禁用此按钮,以防止他再次点击它
I have a button doing a long function, I want to disable this button after the user once click on it to in order to prevent him from clicking it again many times
按钮被禁用,但问题是在功能完成后按钮再次启用
i尝试放置 button.setEnabled(false);
在一个新的线程但它不起作用
The button gets disabled but the problem is after the function finished the button gets enabled again
i tried to put button.setEnabled(false);
in a new thread but it didn't work either
用于测试此代码示例
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent ae) {
button.setEnabled(false);
for (int i = 0; i < Integer.MAX_VALUE; i++) {
for (int j = 0; j < Integer.MAX_VALUE; j++) {
for (int ii = 0; ii < Integer.MAX_VALUE; ii++) {
}
}
}
}
});
推荐答案
使用用于长时间运行的后台任务。在此中, startButton
操作会执行 setEnabled(false)
,而worker的 done()
实现 setEnabled(true)
。
Use SwingWorker
for long running background tasks. In this example, the startButton
action does setEnabled(false)
, and the worker's done()
implementation does setEnabled(true)
.
