如何使带有匿名内部类actionlistener的JButton在单击时自行删除？ [英] How do I make a JButton with an anonymous innerclass actionlistener remove itself on click?

问题描述

您好，感谢您提前阅读本文，这是我的问题：

Hello and thanks for reading this in advance, here is my problem:

final JButton button = new JButton();

        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent actionevent)
            {
                button.setVisible(false);
                button.validate();
                button.invalidate();
                button.revalidate();
                button.repaint();
            }
        });

我尝试了所有这些操作，只是使该按钮消失了，我也禁用了它，但是我需要它只是消失，而不是消失或什么。背景是variabel，所以我无法制作它，因此它与它的颜色相同，并假装它不存在。有没有人知道如何使它消失？

I have tried all those to just make that button go away, I have disabled it aswell, but I need it to just go away, not fade out or something. the background is variabel so I can't make it so it has the same color as it and pretend it's not there. Does anyone have any clue at all how to make it go away?

编辑：我已经尝试了所有答案，真的很想谢谢你，但是按钮仍然存在：（

EDIT: I've tried all answers uptill now and would really like to thank you, but the button's still there :(

EDIT2 ：我认为由于不断添加按钮，我犯了一个很大的错误我的计时器，感谢所有帮助，这仍然非常有用！

EDIT2: I think I've made quite a big mistake constantly adding buttons because of my timer, thanks for all the help, this still was very usefull!

EDIT3 ：非常感谢，我已经解决了问题在你们的帮助下：）

EDIT3: Thank you all very much, I have fixed the problem with your guys' help :)

推荐答案

如果要删除按钮：

Container parent = button.getParent();
parent.remove(button);
((JComponent) parent).revalidate();
parent.repaint();

如果要从按钮中删除动作监听器，则：

if you want to remove action listener from the button:

public void actionPerformed(ActionEvent actionevent)
{
  button.removeActionListener(this);
}
