2、通知公告模块功能代码:
```cpp
#include <QtWidgets>
// 自定义通知公告类
class Announcement {
public:
QString title;
QString content;
QDateTime createTime;
QString creator;
};
// 自定义通知公告模块窗口类
class AnnouncementModule : public QWidget {
Q_OBJECT
public:
AnnouncementModule(QWidget *parent = nullptr) : QWidget(parent) {
QVBoxLayout *layout = new QVBoxLayout(this);
// 创建通知公告列表
announcementListWidget = new QListWidget(this);
layout->addWidget(announcementListWidget);
// 创建添加通知公告按钮
addButton = new QPushButton("Add Announcement", this);
layout->addWidget(addButton);
connect(addButton, &QPushButton::clicked, this, &AnnouncementModule::addAnnouncement);
