Conway의 Life of Game GUI

Question

나는 Conway의 GOL 복사본을 사용하고 있는데, GUI를 렌더링 할 때 문제가있다.

빠른 실행 : GUI Frame 및 mainPanel을 만들고 BorderLayout으로 설정합니다.

일단 그리드 자체를 인스턴스화하고 mainPanel에 할당하면 그리드에 내 2D 배열이 표시되지만 그렇지 않습니다. 지난 2 시간 동안 내 머리를 벽에 치고 있었다.

FWIW에서는 GUI를 빌드 할 때 IDE를 사용할 수 없습니다. 아래 코드 :

GUI

  import java.awt.*; 
import java.awt.event.*; 
import java.awt.Color; 
import java.awt.GridBagLayout; 
import java.awt.BorderLayout;

import javax.swing.JPanel; 
import javax.swing.border.*; 
import java.util.Observer;

public class GameOfLifeGUI extends JFrame implements Observer { 

    private JPanel mainPanel; 
    private JPanel gridPanel; 
    private JPanel startPanel; 
    private JPanel titlePanel; 
    private JButton start; 
    private Cell cell; 
    private Grid grid; 
    private MouseEvent mouseClicked; 
    private MouseEvent mouseDragged; 
    private MouseEvent mousePressed; 
    private MouseEvent mouseRelease; 
    private MouseListener mouseListener; 

    public GameOfLifeGUI() { 
     super(""); 
     //Create Start Button for startPanel 
     JButton start = new JButton("Start"); 

     //Creates a Grid to add to the panel 
     grid = new Grid(75,75); 

     //Create JPanels 
     mainPanel = new JPanel(); 
     gridPanel = new JPanel(); 
     startPanel = new JPanel(); 
     titlePanel = new JPanel(); 

     /** 
     * Add Grid to gridPanel 
     * Modify Grid(int, int) to change size of Grid. Per spec, this grid should always be 75x75 
     */ 

     //Create gridPanel 
     gridPanel.setLayout(new GridLayout(75,75)); 
     gridPanel.setBackground(Color.WHITE); 
     gridPanel.add(grid); 

     //Set Layout of Panels 
     mainPanel.setLayout(new BorderLayout()); 
     mainPanel.add(gridPanel, BorderLayout.CENTER); 
     mainPanel.add(startPanel, BorderLayout.SOUTH); 
     mainPanel.add(titlePanel, BorderLayout.NORTH); 

     //Add Start Button to startPanel 
     startPanel.add(start); 

     //Creates a window for displaying the GUI 
     this.setTitle("Conway's Game of Life"); 
     this.setSize(1000, 750); 
     this.setLocationRelativeTo(null); 
     this.add(mainPanel); 
     this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     this.setVisible(true); 

    }//end Constructor

더 많은 정보가 필요하면 알려 주시기 바랍니다 - 내 첫 번째 게시물에 덤프를 코딩하고 싶지 않았다.

Answer 1

Grid 클래스에는 paintComponent에 대한 메소드가 없습니다. Java 그래픽 클래스의 drawRect() 메서드를 사용하여 간단한 중첩 for 루프가 문제를 해결했습니다.
