ctk加载插件「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

用ctk加载插件有两种方法，第一种需要自己创建ctkPluginFramework：

//ctk plugin
    ctkPluginFrameworkFactory* ctkFrameWorkFactory = new ctkPluginFrameworkFactory;
    QSharedPointer<ctkPluginFramework> framework = ctkFrameWorkFactory->getFramework();

    try
    {
        framework->init();

        framework->start();

        qDebug() << "[Info] ctkPluginFramework start ...";
    }
    catch (const ctkPluginException &Exception)
    {
        qDebug() << QObject::tr("Failed to initialize the plug-in framework: ") << Exception.what();
        return 1;
    }


    //install plugin
    ctkPluginContext* pluginContext = framework->getPluginContext();
    QSharedPointer<ctkPlugin> Plugin = pluginContext->installPlugin(QUrl::fromLocalFile("。。/liborg_ctk_example.dll"));
    Plugin->start(ctkPlugin::START_TRANSIENT);

还有一种比较简单的利用ctkPluginFrameworkLauncher

 ctkPluginFrameworkLauncher::addSearchPath(path, true); //添加插件的搜索路径
	bool SUCCEEDED;
	try
	{
		SUCCEEDED = ctkPluginFrameworkLauncher::start(pluginSymbolicName);   //pluginSybolName为插件的符号名，比如在MF文件中的 Plugin-SymbolicName: org.ctk.example，这里就是“org.ctk.example”
	}

	catch (ctkPluginException &e)
	{
		std::cout << "Error in " << pluginSymbolicName << " " << e.message().toStdString() << std::endl;
		const ctkException* e2 = e.cause();

		if (e2)
			std::cout << e2->message().toStdString() << std::endl;
		return LOAD_FAILED;
	}

	catch (ctkRuntimeException &e)
	{
		std::cout << "Error in " << pluginSymbolicName << " " << e.what() << std::endl;
		const ctkException* e2 = e.cause();

		if (e2)
			std::cout << e2->message().toStdString() << std::endl;
		return LOAD_FAILED;
	}
	catch (...)
	{
		std::cout << "Error in " << pluginSymbolicName << std::endl;
		return UNKNOW_EXCEPTION;
	}

获取pluginContext用下面方法

 ctkPluginFrameworkLauncher::getPluginContext()
