Access GUI components from another class

Question

I\'m new to Java and I\'ve hit a brick wall. I want to access GUI components (that have been created in one class) from another class. I am creating a new GUI class from one

Answer 1

There is actually no need to use a class that implements ActionListener.

It works without, what might be easier to implement:

public class SomeActionListener {

private Gui gui;
private JButton button1;

    public SomeActionListener(Gui gui){

        this.gui  = gui;
        this.button1 = gui.getButton();
        this.button1.addActionListener(l -> System.out.println("one"));
    }

}

and then, like others have elaborated before me in this topic:

public class GUI {
    private JButton button = new JButton();

    public GUI() {
        // pass this instance of GUI to other class
        SomeActionListener listener = new SomeActionListener(GUI.this);
    }

    public JButton getButton() {
        return button;
    }
}
