Updating GUI by modifying a variable from another class not working java
0
I am trying to disable a JButton in the GUI class, by incrementing the turn variable from another class - the test class. This is a simplified and modified excerpt from a bigger school project. Trying to modify the view or GUI from the controller class based on data given back from the model.
This is the GUI class
import java.awt.event.*;
import javax.swing.*;
public class test implements ActionListener {
private int turn;
private JFrame d;
private JButton a;
private int clicked;
public test() {
clicked=0;
turn=0;
d = new JFrame();
a = new JButton();
d.add(a);
a.addActionListener(this);
d.setSize(75,150);
d.setVisible(true);
}
public int getTurn() {
return turn;
}
public void setTurn(int turn) {
this.turn = turn;
}
public int getClicked() {
return clicked;
}
public void setClicked(int clicked) {
this.clicked = clicked;
}
public static void main(String args) {
// TODO Auto-generated method stub
new test();
}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
clicked=1;
if(turn==3) {
((JButton)e.getSource()).setEnabled(false);
}
}
}
While this is the class that attempts to make the GUI changes
public class test2 {
private int turn;
private test gui;
public test2() {
gui = new test();
while(gui.getTurn()<3){
play();
}
}
public void play() {
if(gui.getTurn()<=3 && gui.getClicked()==1) {
gui.setTurn(gui.getTurn()+1); //update the turn variable in the gui
gui.setClicked(0);
}
}
public static void main(String args) {
new test2();
}
}
Any help is highly appreciated

TBH I am not sure what you are trying to achieve.while(gui.getTurn()<3){ play(); }is going to be looping very fast and any multi^threaded updates are not going to be noticed.
