您好，StartupCommand PureMVC cpp与CMake

Question

在execute() Startup SimpleCommand中显示"Hello Startup“的最简单的CMakeLists.txt、main.cpp和PureMVC sources示例是什么？

PureMVC源码是here

理想的解决方案可以是github项目的链接。

您应该编译相应的dll和lib (调试或发布静态|共享)，包括PureMVC文件。也许你可以从PureMVC::Patterns::Facade派生一个外观，覆盖必要的虚函数。因为在C++和类Java编程语言之间是不同的，所以被覆盖的initializeController()不会在基类的构造函数中被调用！下面是一个派生示例：

class ApplicationFacade
    : public virtual IFacade
    , public Facade
{
    friend class Facade;
public:
    static const string STARTUP;
    static const string EXIT;
protected:
    ApplicationFacade(void)
        : Facade(this, "ApplicationFacade")
    {
        initializeController();
    }

public:
    static ApplicationFacade& getInstance(void)
    {
        if (Facade::hasCore("ApplicationFacade"))
            return *(dynamic_cast<ApplicationFacade*>(&Facade::getInstance("ApplicationFacade")));
        return *(new ApplicationFacade());
    }

protected:
    virtual void initializeNotifier(string const& key)
    {
        Facade::initializeNotifier(key);
    }
    virtual void initializeFacade()
    {
        Facade::initializeFacade();
    }

    virtual void initializeController(void)
    {
        Facade::initializeController();
        StartupCommand* startupCommand = new StartupCommand();
        registerCommand(STARTUP, startupCommand);
        ExitCommand* exitCommand = new ExitCommand();
        registerCommand(EXIT, exitCommand);
    }

    ~ApplicationFacade()
    {
    }
};
const string ApplicationFacade::STARTUP = "startup";
const string ApplicationFacade::EXIT = "exit";

StartupCommand和ExitCommand派生自PureMVC::Patterns::SimpleCommand，然后在main.cpp中，您可以通过以下方式启动程序：

ApplicationFacade& facade = ApplicationFacade::getInstance();
facade.sendNotification(ApplicationFacade::STARTUP);

并退出：

facade.sendNotification(ApplicationFacade::EXIT);
