c++ - 你好 StartupCommand PureMVC cpp 与 CMake

Question

什么是最简单的示例CMakeLists.txt，main.cpp以及PureMVC sources从 execute() Startup SimpleCommand 显示“Hello Startup”？

PureMVC 源代码在这里

理想的解决方案可能是 github 项目的链接。

您应该编译相应的 dll 和 lib（Debug 或 Release [static|shared]），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 C++ 和类 Java 编程语言不同，重写的 initializeController() 不会在基类的构造函数中调用！这是一个派生示例：

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);
