There is this code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

class Hello extends JDialog {
  public Hello(JFrame jfr) {
    super(jfr, true);
    JButton ok = new JButton("ok");
    ok.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        setVisible(false);
      }	
    });
    setSize(100,100);
    pack();
    setVisible(true);
  }
}


public class test extends JApplet {

  public void init() {
    try {
      SwingUtilities.invokeAndWait(new Runnable () {
        public void run () {
          makeGui();
        }
      });
    }
    catch (Exception e) {
      System.out.println(e);
    }
  }

  public void makeGui () {
    setLayout(new FlowLayout());

    JButton tb = new JButton("test");
    add(tb);
    Hello hello = new Hello(null);
    setVisible(true);
  }
}

This applet is called from the html page of the view:

<!DOCTYPE html>
<html>
<body>
<applet code="test.class" width = 1000 height = 750>ehwlhewle </applet>
</body>
</html>

When I try to launch in the Firefox browser, I get just a white page, the Hello dialog box is not displayed. At the same time, dialog boxes called through JOptionPane.showMessageDialog work fine.

OS - Archlinux, Java - 1.8

What am I doing wrong?

1. You have not added anything to this dialog. Or rather, in its content pane . And don't forget the LayoutManager.
2. The call to setSize() is ignored because you called pack() after it.
Well, you don't need to call setVisible() in the constructor.
