linux下qt五子棋

在Linux下使用Qt编写五子棋游戏的步骤如下：

1. 安装Qt Creator和Qt库。

2. 创建一个新的Qt项目，选择Qt Widgets Application。

3. 在项目中添加五子棋游戏所需的所有文件，包括源代码、图像和资源文件等。

4. 在Qt Creator中设计游戏界面，包括棋盘和棋子的显示、游戏状态的提示等。

5. 实现游戏逻辑，包括落子、判断胜负、悔棋等。

6. 编译并运行程序，进行测试和调试。

以下是一个简单的五子棋游戏的示例代码：

#include <QtWidgets>

class ChessBoard : public QWidget
{
public:
    ChessBoard(QWidget *parent = nullptr);

protected:
    void paintEvent(QPaintEvent *event) override;
    void mousePressEvent(QMouseEvent *event) override;

private:
    enum { None, Black, White };
    int board[15][15];
    int turn;

    QPoint getChessPoint(QPoint point);
    bool isWin(int row, int col);

    QPixmap blackChessPixmap;
    QPixmap whiteChessPixmap;
};

ChessBoard::ChessBoard(QWidget *parent)
    : QWidget(parent), turn(Black)
{
    setFixedSize(600, 600);

    blackChessPixmap = QPixmap(":/images/black.png");
    whiteChessPixmap = QPixmap(":/images/white.png");

    memset(board, None, sizeof(board));
}

void ChessBoard::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
    painter.setRenderHint(QPainter::Antialiasing, true);

    QPen pen(Qt::black, 2, Qt::SolidLine);
    painter.setPen(pen);

    int boardWidth = width() - 40;
    int boardHeight = height() - 40;
    int gridSize = boardWidth / 14;

    for (int i = 0; i < 15; i++) {
        int xPos = 20 + i * gridSize;
        int yPos = 20 + i * gridSize;
        painter.drawLine(20, yPos, boardWidth + 20, yPos);
        painter.drawLine(xPos, 20, xPos, boardHeight + 20);
    }

    for (int i = 0; i < 15; i++) {
        for (int j = 0; j < 15; j++) {
            if (board[i][j] == Black) {
                QPoint point(20 + i * gridSize - gridSize / 2, 20 + j * gridSize - gridSize / 2);
                painter.drawPixmap(point, blackChessPixmap);
            } else if (board[i][j] == White) {

                painter.drawPixmap(point, whiteChessPixmap);
            }
        }
    }
}

void ChessBoard::mousePressEvent(QMouseEvent *event)
{
    if (event->button() != Qt::LeftButton) {
        return;
    }

    QPoint point = getChessPoint(event->pos());

            memset(board, None, sizeof(board));

                count++;
            }

在代码中，我们继承了QWidget类，实现了五子棋游戏的棋盘和棋子的显示，以及游戏逻辑的实现。在paintEvent()函数中，我们使用QPainter类来绘制棋盘和棋子的显示。在mousePressEvent()函数中，我们实现了落子功能，并且在判断胜负后弹出提示框。在isWin()函数中，我们使用了一个简单的算法来判断是否胜利。最后，在main()函数中，我们创建了一个ChessBoard对象，并显示出来，启动了游戏。
