I am working on a tic tac toe program. In it I have 2 buttons. Whenever I hit new game, the newGameBoard function is supposed to run and make a new board. However, the screen just goes blank! I can't figure it out and would appreciate help. Sorry if I am not posting in the correct format, I am new here.
Thanks so much!

Move mainWindow.setVisible(true) to the end of init(). You don't want to set the frame to visible until you've added everything to it. That way it will validate and layout its subcomponents.
Another solution is to manually call mainWindow.validate() at the end of init(). That's what you have to do if you add components to the frame after making it visible.

use paintAll() or validate() on mainWindow:
mainWindow.validate();
instead of :
mainWindow.repaint(100);
validate and paintAll() as described in API doc.
Your changed code looks like:

Use of JButton array Java

I am not sure what I am doing wrong. I am trying to create 4 buttons using the arrays and passing the method to the Set Panel class. When I run it I only get one button. Any help would be great. Essentially what I want is a Panel with four buttons, through the use of Methods.
public class SetButtons extends JButton implements ActionListener {
JButton [] buttonArray = new JButton[4];
JButton exitBtn, newGameBtn, checkBtn, clearBtn;
Font myFont = new Font("ink free", Font.BOLD,22);
public SetButtons(){
this.exitBtn = new JButton("Exit");
this.newGameBtn = new JButton("New Game");
this.checkBtn = new JButton("Check Answer");
this.clearBtn = new JButton("Clear");
this.buttonArray[0] = exitBtn;
this.buttonArray[1] = newGameBtn;
this.buttonArray[2] = checkBtn;
this.buttonArray[3] = clearBtn;
for (int i = 0; i < 4; i++){
this.buttonArray[i].addActionListener(this);
this.buttonArray[i].setFont(myFont);
this.buttonArray[i].setFocusable(false);
this.buttonArray[i].setLayout(new FlowLayout());

Button not displaying frame connected to it

I am trying to write code for an application I'm making, I have my main frame with 6 buttons on them. When I push one of my buttons, it is meant to bring up a frame that has a tabbed layout set up.
I have the tabbed frame coded correctly and when I set each frame as visible they will appear to screen but they don't appear when the button is pushed.
I have action listeners connected to the buttons and the frames I want to connect with them as well as constructors but for some reason I can't get my code to work correctly.
I have added my driver and my first two forms I'm trying to connect to each other.

jPopupMenu not hiding, after clicking background jFrame

I'm using a JPopupMenu which contains multiple jCheckBoxMenuItem. User can check/uncheck several CheckBox. But when I click on JFrame the PopupMenu is not hiding.
This the entire code.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class PopupTest extends JFrame {
JButton button1;
public PopupTest() {
setTitle("Popup Test !");
setSize(400, 400);

}
}
Please help. Thanks.

First of all, your code is not really the best way to do such thing. You shouldn't create a new menu each time the button is clicked but rather create it once and keep a reference to it as field.
The reason PopupMenu does not hide is that you explicitly call setVisible(true); and you try to setVisible(false); in the very same ActionListener which is assigned to the button, not the frame.
You could:
1. Add another listener to the frame to set menu visiblity to false when clicked
2. Use show method instead of setVisible:
menu.show(button1, 0, button1.getHeight());
instead of
menu.setLocation((int) p.getX(), (int) p.getY() + button1.getHeight());
menu.setVisible(true);
However in our case, this causes other issues with menu disappearing. IMO the best way is to redesign your code.

Adding and removing JButtons in the code

So I am relatively new to Java and trying to create a checkers game using JButtons for the board and for the pieces. However I cannot seem to be able to remove a JButton via the ActionListener. Any advice would be appreciated.
public static void main(String[] args) {
checkersBeBitchin begin = new checkersBeBitchin();
}
public checkersBeBitchin(){
box.setLayout(new BorderLayout());
makeBoard();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setSize(600,600);
setTitle("Checkers");
}
private void makeBoard() {
JPanel board = new JPanel();
board.setLayout(new GridLayout(8,8));
for (int i=0; i<8; i++){
for (int j=0; j<8; j++) {
squares[i][j] = new JButton();
ActionListener actionListener = new Board();
squares[i][j].addActionListener(actionListener);
if((i%2 != 0 && j%2 !=0) ||(i%2==0 && j%2 == 0) ){
squares[i][j].setBackground(Color.black);
pieceTracker[i][j]=0;
//System.out.println("Black"+i+","+j); debugging
if(i<3){
int blue = 1;
Icon piece = new ImageIcon(getClass().getResource("/resources/piece.png"));
JButton button = new JButton(piece);
//squares[i][j].setRolloverIcon("image dir") to make it prettier down the road.
squares[i][j].add(button);
pieceTracker[i][j]=blue;
ActionListener Listener = new Blue();
button.addActionListener(Listener);
}
else if (i>4){
int red=-1;
Icon piece = new ImageIcon(getClass().getResource("/resources/piece2.png"));
JButton button = new JButton(piece);
squares[i][j].add(button);
pieceTracker[i][j]=red;
ActionListener Listener = new Red();
button.addActionListener(Listener);
//squares[i][j].setRolloverSelectedIcon("/resources/piece2alt.png");
}
}
else{
squares[i][j].setBackground(Color.white);
pieceTracker[i][j]=0;
//System.out.println("White"+i+","+j); //debugging
}
board.add(squares[i][j]);
}
}
box.add(board, BorderLayout.CENTER);
}
private class Blue implements ActionListener{
public void actionPerformed (ActionEvent e){
System.out.println("You sexy Blue beast.");
Object x = e.getSource();
System.err.println(x);
squares.remove(x);

squares.remove? Should it read squares.remove(x)? Can we see the definition of squares? Is it an array? You must remove the button from the BOARD not the square, e.g. board.remove(x)

java JFame will not work when started by actionPerformed

I have been googling an sherthing for an solution to this problem a lot but can't find any answer how to fix this. My problem is that when i start a new jframe from an actionevent from pressing a button the class white the JFrame opens but then the programs starts to freeze and the pop up windows stays blank.
Her is the cod i apologize if there is some bad programing or some words in swedish:
The start upp class:
import java.util.ArrayList;
public class maineClassen {
ArrayList<infoClass> Infon = new ArrayList<>();
public static void main (String [] args)
{
referenser referens = new referenser();
Startskärmen ss = new Startskärmen(referens);
}
}
The "startskärm" the first screen to com to:
public class Startskärmen extends JFrame implements ActionListener {
referenser referens;
ArrayList<infoClass> Infon;
JButton öppna = new JButton("open");
JButton ny = new JButton("create new");
JButton radera = new JButton("erase");
JScrollPane pane = new JScrollPane();
DefaultListModel mod = new DefaultListModel();
JList list = new JList(mod);
JScrollPane sp = new JScrollPane(list);
JLabel texten = new JLabel("pre-alpha 0.1");
public Startskärmen(referenser re)
{
//references should be sent by itself or received
referens = re;
Infon = referens.getInfoReferens();
//build up the window
JPanel labelPanel = new JPanel();
labelPanel.setLayout(new BoxLayout(labelPanel, BoxLayout.LINE_AXIS));
labelPanel.setBorder(BorderFactory.createEmptyBorder(10,10,0,10));
labelPanel.add(texten);
JPanel scrollPanel = new JPanel();
scrollPanel.setLayout(new BoxLayout(scrollPanel, BoxLayout.LINE_AXIS));
scrollPanel.setBorder(BorderFactory.createEmptyBorder(10,10,10,10));
scrollPanel.add(sp);// man kan ocksä sätta in --> pane <--
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new BoxLayout(buttonPanel, BoxLayout.LINE_AXIS));
buttonPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 10, 10));
buttonPanel.add(Box.createHorizontalGlue());
buttonPanel.add(öppna);
buttonPanel.add(Box.createRigidArea(new Dimension(10, 0)));
buttonPanel.add(ny);
buttonPanel.add(Box.createRigidArea(new Dimension(10, 0)));
buttonPanel.add(radera);
Container contentPane = getContentPane();
contentPane.add(labelPanel,BorderLayout.NORTH);
contentPane.add(scrollPanel, BorderLayout.CENTER);
contentPane.add(buttonPanel, BorderLayout.PAGE_END);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setSize(500, 500);
//adda action listener

}

public void skapaNyIC()
{

Infon.get(Infon.size() -1).referenser(Infon); //Infon.get(Infon.size() -1)
mod.addElement(Infon.get(Infon.size() -1).getName());
}
public void actionPerformed(ActionEvent e) {
if(e.getSource() == ny)
{
skapaNyIC();
}
else if(e.getSource() == öppna)
{
JOptionPane.showMessageDialog(texten,"This function doesn't exist yet");
}
else if(e.getSource() == radera)
{
JOptionPane.showMessageDialog(texten, "This function doesn't exist yet");
}
}
}
The class where the information will be stored and that creates the window (class) that will show the info:
public class infoClass {
ArrayList<infoClass> Infon;
private infoClass ic;
private String namn = "inget namn existerar";
private String infoOmInfo = null;
private int X_Rutor = 3;
private int Y_Rutor = 3;
private String[] information = new String[X_Rutor + Y_Rutor];
//info om dessa värden
public infoClass()
{
}
public void referenser(infoClass Tic)
{
ic = Tic;
infonGrafiskt ig = new infonGrafiskt(ic);
}
public void referenser(ArrayList<infoClass> Tic)
{
ic = Tic.get((Tic.size() - 1 ));
System.out.println("inna");
infonGrafiskt ig = new infonGrafiskt(ic);
ig.setVisible(true);
System.out.println("efter");
}
public String namnPåInfon()
{
return namn;
}
//namnen
public String getName()
{
return namn;
}
public void setNamn(String n)
{
namn = n;
}
//xkordinaterna
public int getX_Rutor()
{
return X_Rutor;
}
public void setX_Rutor(int n)
{
X_Rutor = n;
}
//y kordinaterna
public int getY_Rutor()
{
return Y_Rutor;
}
public void setY_Rutor(int n)
{
Y_Rutor = n;
}
//informationen
public String[] getInformationen()
{
return information;
}
public void setInformationen(String[] n)
{
information = n;
}
//infoOmInfo
public String getinfoOmInfo()
{
return infoOmInfo;
}
public void setinfoOmInfo(String n)
{
infoOmInfo = n;
}
}
The class that will show the info created by the window a bow:
public class infonGrafiskt extends JFrame implements ActionListener{
infoClass ic;
infonGrafiskt ig;
//tillrutnätet
JPanel panel = new JPanel(new SpringLayout());
boolean pausa = true;
//sakerna till desigen grund inställningar GI = grund inställningar
JButton GIklarKnapp = new JButton("Spara och gå vidare");
JTextField GInamn = new JTextField();
JLabel GINamnText = new JLabel("Namn:");
JTextField GIxRutor = new JTextField();

so my problem now is that i can't create a new "infoclass" that will show the info in the "infoGrafikst" class. with the code:
Infon.add(new infoClass());
Infon.get(Infon.size() -1).referenser(Infon); //Infon.get(Infon.size() -1)
mod.addElement(Infon.get(Infon.size() -1).getName());
that am triggered by an button click.
Sorry for all the cod, but didn't know how to show my problem in another way.
Thanks a lot. I did find out that it was this code
int m =1;
try {
while(m ==1) {
Thread.sleep(100);
if(pausa == false)
m =2;
}
} catch(InterruptedException e) {
}
that made it not work...

Well I haven't gone through your code may be beacuse I am too lazy to read pages of code.Well i think the new window you are creating must be interfering with EDT.
Well i have done a short example which may help you, and its smooth:
import java.awt.event.ActionEvent;
import javax.swing.*;
public class FrameLaunch {
void inti(){
final JFrame f=new JFrame();
final JFrame f2=new JFrame();
final JTextArea ja=new JTextArea();
JButton b =new JButton("press for a new JFrame");
f2.add(b);
f2.pack();
f2.setVisible(true);
b.addActionListener(new java.awt.event.ActionListener()
{
public void actionPerformed(ActionEvent e) {
f2.setVisible(false);
f.setSize(200,200);
ja.setText("THIS IS NOT FROZEN");
f.add(ja);
f.setVisible(true);
f.setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
}
});
}
public static void main(String[] args)
{
FrameLaunch frame = new FrameLaunch();
frame.inti();
}
}
