Sticky interface button or how to add a Swing function call to an event?

Question

Java

There is a code:

//Обработчик при нажатии на кнопки в окошке интерфейса
    class ListenerAction_start implements ActionListener {
      public void actionPerformed(ActionEvent e) {
            System.out.println("\n" + "Вы выбрали -> ["+ 
                                e.getActionCommand() + "]" + "\n");
            Start_main();
        }
    }
    
    class ListenerAction_stop implements ActionListener {
      public void actionPerformed(ActionEvent e) {
            System.out.println("\n" + "Вы выбрали -> ["+ 
                                e.getActionCommand() + "]" + "\n");
        }
    }
    
    // подключение монитора событий нажатия на кнопки интерфейса
    button.addActionListener(new ListenerAction_start());
    button2.addActionListener(new ListenerAction_stop());

Why, after a single click on the first button, it sticks by calling the Start_main () function. How to make it so that when the button is pressed, the Start_main function is called, and when button2 is pressed, another function is called without blocking the interface window (without sticking)

Answer 1

Your main processing cycle is blocked. Use SwingYtilities. invokeLater() and wrap it in Runnable.
