在linux系统中使用qt creator实现2048源代码

首先需要安装Qt Creator和Qt库。安装完成后，可以按照以下步骤进行实现：

1. 新建Qt Widgets Application项目。

2. 在项目中添加四个Label和一个PushButton，用于显示游戏界面和重新开始游戏。

3. 编写游戏逻辑代码，实现游戏的初始化、移动、合并等操作。

4. 将游戏逻辑代码与界面进行连接，实现游戏的展示和操作。

5. 编写结束判断代码，当游戏结束时弹出游戏结束提示框。

6. 部署程序，生成可执行文件。

下面是一个简单的2048实现示例代码：

mainwindow.h文件：

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QLabel>
#include <QPushButton>

class MainWindow : public QMainWindow

    void moveLeft();
    void moveRight();
    void moveUp();
    void moveDown();
    bool canMove();
    bool canCombine();
    bool isGameOver();
    void gameOver();
    int getRand(int min, int max);

private slots:
