如何设置"JOptionPane.showMessageDialog"的位置； [英] How to set the location of "JOptionPane.showMessageDialog"

问题描述

我要显示JOptionPane.showMessageDialog消息

• 屏幕上的任何地方.
• 相对于JFrame. (不在JFrame的中心)

例如，这将在作为参数thisFrame

For example this will display the message at the centre of the JFrame provided as argument thisFrame

 JOptionPane.showMessageDialog(thisFrame, "Your message.");

这将在屏幕中央显示该消息，而与任何JFrame无关.

And this will display the message at the centre of the screen irrelative to any JFrame.

JOptionPane.showMessageDialog(null, "Your message.");

• 我想要的是在我想要的任何位置设置邮件的位置

  • what I want is to set the location of the message any place I want

    我想要的是设置消息相对于JFrame的位置(而不是JFrame的中心)

    what I want is to set the location of the message relative to the JFrame (not at the centre of the JFrame)

    如何?

    import javax.swing.JButton;
    
    public class CustomDialog extends JDialog {
        private JPanel myPanel = null;
        private JButton yesButton = null;
        private JButton noButton = null;
    
        public CustomDialog(JFrame frame, boolean modal, String myMessage) {
        super(frame, modal);
        myPanel = new JPanel();
        getContentPane().add(myPanel);
        myPanel.add(new JLabel(myMessage));
        yesButton = new JButton("Yes");
        myPanel.add(yesButton);
        noButton = new JButton("No");
        myPanel.add(noButton);
        pack();
        //setLocationRelativeTo(frame);
        setLocation(200, 200); // <--
        setVisible(true);
        }
    }
