用qt写一个 完整打地鼠小游戏

好的，下面是一个简单的打地鼠游戏的Qt代码，供您参考：

#include <QtWidgets/QApplication>
#include <QtWidgets/QWidget>
#include <QtWidgets/QPushButton>
#include <QtWidgets/QLabel>
#include <QtCore/QTimer>
#include <QtCore/QTime>
#include <QtCore/QRandomGenerator>

        m_scoreLabel = new QLabel(this);

        m_scoreLabel->setText(tr("得分: 0"));

        m_timeLabel = new QLabel(this);

该游戏使用了Qt的基本组件，包括`QLabel`、`QPushButton`、`QTimer`和`QPainter`等。在游戏开始后，每秒钟随机出现一个地鼠，玩家需要点击地鼠来得分。游戏时间为30秒，时间到后游戏结束，显示得分和重新开始按钮。
