当我从addMouseListener关闭我的fram时，它说这是不兼容的类型，那么我可以改变它吗？

Question

我的代码dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING))不起作用：

jTable1.addMouseListener(new MouseAdapter() {

        @Override
        public void mouseClicked(MouseEvent e) {

            if (e.getClickCount() == 2) {
                int select = jTable1.getSelectedRow();
                int choi = JOptionPane.showConfirmDialog(null, "Voulez Vous vraiment choisir ce client ?");
                if(choi == 0){
                    Utile.idClient=jTable1.getModel().getValueAt(select, 0).toString();
                    dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));

                }

            }
        }
    });

Answer 1

由于您使用的是内部类， this指向内部实例。 要获取外部实例，请使用：

MyFrame.this 

Answer 2

dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));

“ this”是指MouseListener，而不是框架。

要找到活动窗口，您可以执行以下操作：

Window window = SwingUtilities.windowForCompoent( e.getComponent() );
dispatchEvent(new WindowEvent(window, WindowEvent.WINDOW_CLOSING));
