qt实现扫雷四：窗口设计

扫雷的主窗口，main函数里运行这个窗口

问题总结

1、计时程序，1s触发一次，更新游戏时间

#include <QTimer>
QTimer *past_timer;
past_timer = new QTimer(this);
past_timer->setInterval(1000);
connect(past_timer,SIGNAL(timeout()),this,SLOT(updateTimeCount()));
past_timer->start();

2、继承自QMainWindow类，可以添加菜单，下拉菜单里设计选项，新游戏或修改雷区参数。

#include <QMenu>
#include <QMenuBar>
QMenu *tools_menu;
QMenuBar *menu;
tools_menu = new QMenu();
tools_menu->setTitle(\"setting\");
tools_menu->addAction(\"close\", this, SLOT(close()));
tools_menu->addAction(\"new game\", this, SLOT(setNewGame()));
tools_menu->addAction(\"self define\", this, SLOT(selfDefineNewGame()));
menu = new QMenuBar(this);
menu->setGeometry(0, 0, 20, 20);
menu->addMenu(tools_menu);

3、定义槽函数，需要定义为 private slots

private slots:
    void setNewGame();
    void selfDefineNewGame();
    void updateTimeCount();

4、程序运行效果如下

头文件

1、宏定义雷区偏移位置

#define     ROW_START       20
#define     COLUMN_START    0

2、窗口类，继承自QMainWindow

class thunder_window : public QMainWindow
{
    Q_OBJECT

public:
    thunder_window(QWidget *parent = 0);
    ~thunder_window();

protected:
    //重载鼠标点击事件响应
    void mousePressEvent(QMouseEvent *event);

private slots:
    //下拉菜单中选择new game响应函数
    void setNewGame();
    //下拉菜单中选择self define响应函数
    void selfDefineNewGame();
    //1s计时器触发时间更新响应函数
    void updateTimeCount();

private:
    thunder_view *tv;
    QMenu *tools_menu;
    QMenuBar *menu;
    QLabel *number_label;
    int current_number;
    QTimer *past_timer;
    int time_count;
    QLabel *time_label;
};
