Чтобы сделать длинный рассказ коротким, у меня есть два объекта JPanel
в моем JFrame
, одна из них - панель настройки, а другая - графическая панель. Когда я изменяю размер окна, графические панели не изменяют размер соответственно.Изменить размер JPanel после установки цвета
У меня есть два класса, один из них GUImodel
класса, а другой является ModelSim
(имитационная модель) класс, в котором GUImodel
класс визуализировать части моделирования в ModelSim
.
Где i, j индексы в методе рисования (770,460) пикселей в моей картинке JPanel
. fillRect
цвет каждого пикселя 770x460 пикселей на основе моего определения в приведенном выше коде. Как изменить размер изображения JPanel
, расширив окно. По логике, изменив размер графической панели, цветные пиксели больше не будут иметь квадратную форму, что в моем случае прекрасное.
Пожалуйста, помогите мне, как я могу это сделать? Дайте мне знать, если вам нужна любая другая информация
Вот работоспособной код; первый класс - GUICA, а другой - ModelSim.
GUICA:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ComponentEvent;
import java.awt.event.ComponentListener;

// This code provide a simple GUI for Cellular Automata
// Notice that we are going to extend our super class JFrame which is the main window of our simulation
// Inside this JFrame, we are going to add two subframes, which are called JPanels.
public class GUICA extends JFrame {
// We need to make to Jpanels inside the main Jframe
// First Jpanel is adjustPanel
private JPanel adjustPanel;
// Second Jpanel is graphicPanel
private JPanel graphicPanel;
// Now it is the time to create buttons
private JButton startButton;
private JButton resetButton;
private JButton stopButton;
// We need to make an object from our model to implement that one in GUI part
private ModelSim model;
// We need also timer to re-implement (update) our simulation
private Timer timer;
// Detrmining the initial values of Windows panel main size
static int widthPixel = 766;
static int heightPixel = 468;
Rectangle bounds;
// Now, that's the time to create our constructor
public GUICA(){
// Here super is our JFrame and the string defines the name of our Frame.
super("Cellular Automata Evacuation");
// The below code will close the window(JFrame), once we have click on window exit
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//lets define the default size of our window page(main JFrame), where the first value is the x and second one is y;
setSize(widthPixel,heightPixel);
// First let's define the role of our timer in our future simulation. We first have to initialize our object in
// the constructor, then with an actionlistener, we will define the role of timerlistener with a nested class.
timer = new Timer(1,new TimerListener());
// We need to initialize our buttons right now.
// The important factor here is the actionlistener, we need to addactionlistener to each button to define their duties.
// Their duties can be defined by a nested class (which is defined inside our main class)
startButton = new JButton("Start");
startButton.addActionListener(new StartListener());
resetButton = new JButton("Reset");
resetButton.addActionListener(new ResetListener());
stopButton = new JButton("Stop");
stopButton.addActionListener(new StopListener());
// There are many options to put the buttons in different part of the JPanel, I am going to use not the easiest one
// but the handiest one. We want to accommodate our buttons inside adjustPanel
adjustPanel = new JPanel(new GridBagLayout());
// The below code is for determining the position of our buttons
GridBagConstraints grid = new GridBagConstraints();
grid.insets = new Insets(10,10,10,10);

grid.gridy = 3;
adjustPanel.add(white,grid);

grid.gridy = 4;
adjustPanel.add(stopButton,grid);
// We can determine that how much of the space is going to be belonged to adjustPanel
adjustPanel.setPreferredSize(new Dimension(100,heightPixel));
// We need to add this panel to our main JFrame panel; also we can determine where we want to place this panel
// I won't use grid method to place this panel. However,instead, I use the simplest way to determine the position of panels
setLayout(new BorderLayout());
