@九江在天：今天学到关于Qt的几个关键词：Q_DISABLE_COPY(Bluetooth)，friend ，
Q_DECLARE_PRIVATE(Bluetooth) Q_Q，
Q_DECLARE_PUBLIC(Bluetooth) Q_D,个人觉得这个用法非常好，有这么一个项目，全部都是以这种方式做的，pimpl的方式。代码如下：
launcher.h
#include <QObject>
class LauncherPrivate;
class Launcher : public QObject
{
Q_OBJECT
Q_DISABLE_COPY(Launcher)
public:
explicit Launcher(QObject *parent = nullptr);
~Launcher();
private:
LauncherPrivate* const d_ptr;
Q_DECLARE_PRIVATE(Launcher)

public slots:
void onStartComplete();
signals:

};

鸿蒙电脑操作系统概念版这一次，我们来看一看鸿蒙操作系统，鸿蒙的电脑现在还没有，连鸿蒙电脑操作系统都没有呢，我做了一个概念版(PPT)，希望真正的鸿蒙比我的要好
