用qt写一个五子棋程序

Qt是一个开源的C++图形用户界面库，可以用来开发跨平台的桌面应用程序。如果你想用Qt写一个五子棋程序，可以使用Qt的图形界面部件，如QMainWindow、QWidget、QPushButton、QLabel等，来构建五子棋的界面；可以使用QPainter来绘制棋盘和棋子；还可以使用QMouseEvent来处理鼠标事件，实现玩家下棋的功能。

以下是一段代码的示例：

#include <QtWidgets>

class ChessBoard : public QWidget
{
    Q_OBJECT

public:
    ChessBoard(QWidget *parent = nullptr);

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

private:
    int board[15][15];
};

ChessBoard::ChessBoard(QWidget *parent) : QWidget(parent)
{
    setFixedSize(450, 450);
    memset(board, 0, sizeof(board));
}

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

    // 绘制棋盘
    for (int i = 0; i <= 15; i++) {
        painter.drawLine(30, 30 + i * 30, 450 - 30, 30 + i * 30);
        painter.drawLine(30 + i * 30, 30, 30 + i * 30, 450 - 30);
    }

    // 绘制棋子
    for (int i = 0; i < 15; i++) {
        for (int j = 0; j < 15; j++) {
            if (board[i][j] == 1) {
                painter.setBrush(Qt::black);
                painter.drawEllipse(QPoint(30 + i * 30, 30 + j * 30), 13, 13);
            } else if (board[i][j] == 2) {
                painter.setBrush(Qt::white);
                painter.drawEllipse(QPoint(30 + i * 30, 30 + j * 30), 13, 13);
            }
        }
    }
}

void ChessBoard::mousePressEvent(QMouseEvent *event)
{
    int x = event->x();
    int y = event->y();
    int i = (x - 30) / 30;
    int j =
