[英]Adding a Button array to a JPanel
I have another problem with my project. 我的项目还有另一个问题。 I have created this GameBoard made out of JButtons (it works as it's supposed to now) but I would need to add it to a JPanel. 我已经创建了由JButtons制成的GameBoard(它现在应该可以正常工作),但是我需要将其添加到JPanel中。 I need to display other things (in other panels) in the window. 我需要在窗口中显示其他内容(在其他面板中)。 But when I tried to add the Button Array to a panel, and add that panel to the window, crazy things started happening (the buttons were very small, the grid was completely broken etc.). 但是,当我尝试将“按钮数组”添加到面板中并将该面板添加到窗口中时,疯狂的事情开始发生(按钮很小,网格完全损坏等)。 How could I add this Button Array to a JPanel and put that in the center of the window? 如何将这个按钮数组添加到JPanel并将其放在窗口的中央? Here is my code: 这是我的代码:
package city;
import java.awt.Color;
import java.awt.Component;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class GameBoard extends JFrame implements ActionListener {
// The overall box count in chess board
public static final int squareCount = 64;
// The Array of buttons (the GameBoard itself)
public Button[][] button = new Button[8][8];
// Colors for all the buttons
public Color defaultColor = Color.WHITE;
public Color darkRedColor = Color.RED;
public Color darkBlueColor = Color.BLUE;
public Color lightBlueColor = Color.CYAN;
public Color lightRedColor = Color.PINK;
public GameBoard(String title) {
// Creates the buttons in the array
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 8; j++) {
button[i][j] = new Button();
add(button[i][j]);
button[i][j].setBackground(defaultColor);
}
}
// Build the window
this.setTitle(title); // Setting the title of board
this.setLayout(new GridLayout(8, 18)); // GridLayout will arrange elements in Grid Manager 8 X 8
this.setSize(650, 650); // Size of the chess board
this.setVisible(true); // Sets the board visible
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // If you close the window, the program will terminate
this.setResizable(false); //The window is not resizable anymore ;)
// Sets some text on the buttons
button[0][3].setText("Red's");
button[0][4].setText("Gate");
button[7][3].setText("Blue's");
button[7][4].setText("Gate");
// Colors the buttons
newGame();
}
// Colors the buttons
public void newGame() {
button[0][0].setBackground(lightRedColor);
button[0][1].setBackground(lightRedColor);
button[0][2].setBackground(lightRedColor);
button[0][3].setBackground(darkRedColor);
button[0][4].setBackground(lightRedColor);
button[0][5].setBackground(lightRedColor);
button[0][6].setBackground(lightRedColor);
button[0][7].setBackground(lightRedColor);
button[1][3].setBackground(darkRedColor);
button[7][0].setBackground(lightBlueColor);
button[7][1].setBackground(lightBlueColor);
button[7][2].setBackground(lightBlueColor);
button[7][3].setBackground(lightBlueColor);
button[7][4].setBackground(darkBlueColor);
button[7][5].setBackground(lightBlueColor);
button[7][6].setBackground(lightBlueColor);
button[7][7].setBackground(lightBlueColor);
button[6][4].setBackground(darkBlueColor);
}
// The ActionListener is not yet used
public void actionPerformed(ActionEvent ae) {
String action = ae.getActionCommand();
}
public static void main(String[] args) {
String title = "City - A Two-Player Strategic Game";
GameBoard gameBoard = new GameBoard(title); // Creating the instance of gameBoard
}
}
And here is a screenshot of the bad GUI that generated: Bad GUI 这是生成的不良GUI的屏幕截图: 不良GUI
Thanks for any help, and good luck everyone with a similar problem! 感谢您的帮助,祝大家有类似问题!
Is this what you are looking for? 这是你想要的? I am not very sure what´s the problem. 我不太确定这是什么问题。
This adds the buttons to a new JPanel and adds this panel to the frame. 这会将按钮添加到新的JPanel并将此面板添加到框架。
JPanel panel = new JPanel(new GridLayout(8, 8));
panel.setSize(650,650);
getContentPane().add(panel, BorderLayout.CENTER);
// Creates the buttons in the array
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 8; j++) {
button[i][j] = new JButton();
panel.add(button[i][j]);
button[i][j].setBackground(defaultColor);
}
}
// Build the window
this.setTitle(title); // Setting the title of board
getContentPane().setLayout(new BorderLayout());
this.setSize(650, 650); // Size of the chess board
this.setVisible(true); // Sets the board visible
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // If you close the window, the program will terminate
this.setResizable(false); //The window is not resizable anymore ;)
