    Default I need help with gui.

    Ok I got this atm.

    PHP Code:

    package rpsgui
    ;

    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.*;
    import javax.swing.Icon;
    import javax.swing.JDialog;
    import javax.swing.JFrame;
    public class 
    RPSgui {

        public static 
    void main(String[] args) {

    // Creates JFrame.
    JFrame jf = new JFrame("RPS - @Xyn") ;
    jf.setSize(500500);
    jf.setVisible(true);    
    jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    // Create Panel
    JPanel jp = new JPanel();
    jp.setVisible(true);        
            
    // Creates Play JButton.
    JButton pla = new JButton("Play RPS");
    pla.setLocation(12050);
    pla.setVisible(true);


    jf.add(jp);
    jf.add(pla);

    me tyl = new me();
    pla.addActionListener(tyl);



        }


    static public class 
    me extends RPSgui implements ActionListener{
        public 
    void actionPerformed(ActionEvent e){
            
    System.out.print("CLICKEDDD");
            
        }
        
    }} 
    The thing I have a question with. Inside the ActionListener is where you put the action of clicking the button right? It works and everything the thing is when someone clicks the bottom I want to remove the button from the frame so i can build a game inside instead.

    But I run into a problem since the buttons located outside the action listener I cannot refer to the button inside the main class...

    Just started doing ActionListener so sorry if they awsner is obvious.

    What error are you getting (can you paste it/them here)? Also, is this PHP, or Java (the code said PHP above it...)?

    Another thing: why is your ActionListener class (me) extending your GUI's class (RPSgui)? I do not think that that extension is necessary for the ActionListener to function correctly.

    I know that I probably didn't need to extend that, I was just testing something. It's java lol, I just enclosed it in PHP.


    I'm not getting an error, I was referring to removing the button in the ActionionListener class but I cannot close the button cause I cannot refer to the button at all in the action listener class.


    Like I want to do

    static public class me extends RPSgui implements ActionListener{
    public void actionPerformed(ActionEvent e){
    pla.remove(JButton1);

    but pla. or my JButton does not get recognized.

    Oh! I see what you mean. Okay. Well, think about this: if you define a variable or Component in the main method, that is the only place from which it can be accessed. So what's the simplest way to allow the Component to be accessed from outside the main method?

    Ohhhh

    So define a JButton like I would a string, and the Jbutton can be accsessed anywhere in the file? Like a regular global variable?

    Yeah. If you define the JButton outside the main method, you can still access it in the main method, and your ActionListener can get to it as well.
