[英]Can't set maximum size of connect 4 grid in Java swing
Right now I am trying to make it so that the connect 4 grid on the gui is always a 7x8 no matter what window size. 现在,我正在尝试使GUI上的connect 4网格始终为7x8,无论窗口大小如何。 I have been trying to set the button array with a
setMaximumSize
and it's not working. 我一直在尝试使用
setMaximumSize
设置按钮数组,但它不起作用。
Here is the code that sets the JButton
array 这是设置
JButton
数组的代码
void ResetGame()
{
JLabel label = new JLabel("Click a column to drop piece");
for(int r=0;r<gameBoard.length;r++)
{
java.util.Arrays.fill(gameBoard[r],0,gameBoard[r].length,'0');
//loop through board columns
for(int c=0;c<gameBoard[r].length;c++)
{
gameButtons[r][c]= new JButton(empty);
panel.add(gameButtons[r][c]);
gameButtons[r][c].setPreferredSize(new Dimension(70,70));
//Allows buttons to be arranged as grid.
GridLayout grid = new GridLayout(0,8);
//Sets into grid.
gameButtons[r][c].setLayout(grid);
gameButtons[r][c].setMaximumSize(new Dimension(0,10));
}
panel.add(label);
}
// loop through array setting char array back to ' ' and buttons array back to empty pic
// reset currentPlayer and numMoves variables
}
Just in case I'll also include the window creation method here. 以防万一,我还将在此处包括窗口创建方法。
public void CreateWindow()
{
//Sets window title and create window object.
JFrame aWindow = new JFrame("Connect Four");
//Set window position and size
aWindow.setBounds(200,100,600,800);
//What close button does.
aWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Make window visible.
aWindow.setVisible(true);
//Sets content area to work with stuff.
aWindow.setContentPane(panel);
//Gets content pane.
Container content = aWindow.getContentPane();
}
Not sure of what you are trying to achieve with setMaximumSize. 不确定您要使用setMaximumSize实现什么。 Without explicit and precise requirements, we can hardly help you.
没有明确和精确的要求,我们几乎无法为您提供帮助。
So, I would suggest that you take a look at the following snippet (which is an SSCCE ) and try to find out what you are doing wrong: 因此,我建议您看一下以下代码片段(这是一个SSCCE ),并尝试找出您在做什么错:
import java.awt.Color;
import java.awt.Graphics;
import java.awt.GridLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class Connect4 {
public class GameButton extends JPanel {
private final int row;
private final int column;
private Color color;
public GameButton(final int row, final int column) {
super();
this.row = row;
this.column = column;
addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
System.out.println("Game button " + row + " " + column + " has been pressed");
}
});
}
public void setColor(Color color) {
this.color = color;
repaint();
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
int size = Math.min(getWidth(), getHeight());
int offset = (int) ((double) size / 10);
size = size - 2 * offset;
if (color == null) {
g.setColor(Color.BLACK);
g.drawOval(offset, offset, size, size);
} else {
g.setColor(color);
g.fillOval(offset, offset, size, size);
}
}
}
protected void initUI() {
JPanel gridPanel = new JPanel(new GridLayout(7, 8));
for (int i = 0; i < 7; i++) {
for (int j = 0; j < 8; j++) {
GameButton gameButton = new GameButton(i, j);
gridPanel.add(gameButton);
}
}
JFrame frame = new JFrame(Connect4.class.getSimpleName());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(gridPanel);
frame.setSize(600, 600);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new Connect4().initUI();
}
});
}
}
setMaximumSize()
puts a bound on how large something can be. setMaximumSize()
限制事物的大小。 Depending on what you are using for a layout manager you want either setPreferredSize()
or setSize()
. 根据您用于布局管理器的内容,您需要
setPreferredSize()
或setSize()
。
