### 设置自启动和关闭自启动
```cpp
void PopupClock::SetAutoStart(bool flag) {
QSettings settings(AUTO_RUN, QSettings::NativeFormat);
//以程序名称作为注册表中的键,根据键获取对应的值（程序路径）
QFileInfo fInfo(QApplication::applicationFilePath());
QString name = fInfo.baseName(); //键-名称
//如果注册表中的路径和当前程序路径不一样，则表示没有设置自启动或本自启动程序已经更换了路径
QString oldPath = settings.value(name).toString(); //获取目前的值-绝对路经
QString newPath = QDir::toNativeSeparators(QApplication::applicationFilePath()); //toNativeSeparators函数将"/"替换为"\"
if (flag)
{
if (oldPath != newPath)
settings.setValue(name, newPath);
}
else {
settings.remove(name);
}
m_pActionAutoStart->setChecked(checkAutoStart());
}
