GridLayout

[Govnor]

Hi,

I am new to this forum, so please tell me if I don’t give enough information in the question.

I am making a small java project (as I am a beginner) that shuffles and deals cards,

But I cannot get my GUI to work by using GridLayout (but it works with FlowLayout)

The code is below and I have commented where it is not working


import javax.swing.*;
import java.awt.*;
import java.awt.event.*;


public class DeckOfCards extends JFrame {
private Card deck[];
private int currentCard;
private JButton dealButton, shuffleButton;
private JTextField displayCard;
private JLabel status;

public DeckOfCards() {
super( "Card Dealing Program"
String faces[] = {"Ace", "Deuce", "Three", "Four",
"Five", "Six", "Seven", "Eight",
"Nine","Ten", "Jack", "Queen", "King"};
String suits[] = {"Hearts", "Diamonds", "Clubs", "Spades"};
deck = new Card[52];
currentCard = -1;

for (int i = 0; i < deck.length; i++){
deck=new Card(faces[i%13], suits[i/13]);
}
Container c = getContentPane();
c.setLayout(new GridLayout(0,5,10,10));
dealButton = new JButton(&quot;Deal card&quot;
dealButton.addActionListener(
new ActionListener(){
public void actionPerformed (ActionEvent e){
Card dealt = dealCard();
if (dealt != null){
displayCard.setText(dealt.toString());
status.setText(&quot;Card #: &quot; + currentCard);






}
else {
displayCard.setText(&quot;NO MORE CARDS TO DEAL&quot;
status.setText(&quot;Shuffle cards to continue&quot;
}
}
}
);
c.add(GridLayout dealButton(&quot;2&quot); //THIS IS NOT WORKING

shuffleButton = new JButton(&quot;Shuffle Cards&quot;
shuffleButton.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e){
displayCard.setText(&quot;SHUFFLING....&quot;
shuffle();
displayCard.setText(&quot;DECK IS SHUFFLED&quot;
}
}
);
c.add(shuffleButton);//WANT THIS TO WORK (WORKS USING FLOWLAYOUT)

displayCard = new JTextField(20);

displayCard.setEditable(false);
c.add(displayCard); //WANT THIS TO WORK (SAME)

status = new JLabel();
c.add(status); //WANT THIS TO WORK (SAME)

setSize(275,50); // set the window size
show(); // show the window
}
public void shuffle(){
currentCard = -1;
for(int i = 0; i < deck.length; i++){
int j = (int)(Math.random() * 52);
Card temp = deck; // swap
deck = deck[j]; // the
deck[j] = temp; // cards
}

dealButton.setEnabled(true);
}

public Card dealCard(){
if (++currentCard < deck.length){
return deck[currentCard];
} else {
dealButton.setEnabled(false);
return null;
}
}


public static void main(String[] args) {
DeckOfCards deckOfCards = new DeckOfCards();

deckOfCards.addWindowListener(
new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
}
);
}
}

//Do not alter any code below this line.
final class Card {
private String face;
private String suit;

public Card(String f, String s){
face = f;
suit = s;
}

public String toString(){
return face + &quot; of &quot; + suit;
}
}

I was looking in API and didn't found any constructor of GridLayout where 0 as first argument has sence

GridLayout(int rows, int cols)
GridLayout(int rows, int cols, int hgap, int vgap) ???
