Qt 程序自定义插件(2)

///
    /// \brief get_moudle_describe
    /// 获取模块的描述信息
    /// \return
    ///
    virtual  std::string get_moudle_describe() const =0;

};

QT_BEGIN_NAMESPACE

#define IBasicModule_iid "com.twsz.tc.ningjian.IBasicModule/1.0"

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid)

QT_END_NAMESPACE

//Q_DECLARE_INTERFACE(IBasicModule,"com.twsz.tc.ningjian.IBasicModule/1.0");

#endif // BASIC_MODULE_INTERFACE_H

基本是纯虚类要在末尾添加  

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid) 即可

2、实现插件
头文件 如下： cpp正常就好了，注意要继承QObject 和 接口类就可以了，还要在在头文件中添加 Q_OBJECT Q_PLUGIN_METADATA(IID "com.twsz.tc.ningjian.IBasicModule/1.0" ) Q_INTERFACES(IBasicModule)
在项目属性中要添加
TEMPLATE = lib CONFIG += plugin

#ifndef STT_BASIC_MOUDLE_H
#define STT_BASIC_MOUDLE_H

#include <QScriptEngine>

using namespace std;

3、使用插件

下面是遍历加载plugins目录下所有实现 IBasicModule 接口的插件 获取相应的实例就可以调用了
头文件记得添加
#include <QPluginLoader>

//注册模块指令
    QDir plugindir = QDir(QDir::currentPath()+"/plugins");
    int i = 0;
    foreach(QString filename,plugindir.entryList(QDir::Files)){
        QPluginLoader loader(plugindir.absoluteFilePath(filename));
        if (IBasicModule * base_moudle = qobject_cast<IBasicModule *>(loader.instance()))
        {
            qDebug()<<base_moudle->get_moudle_name().c_str();

STT_Global::basicModule_map.insert(std::pair<std::string,IBasicModule*>(base_moudle->get_moudle_name(),base_moudle));
            STT_Global::PlugsList.push_back( base_moudle->get_moudle_name());
            base_moudle->init(G_Test_Info,G_Test_Fun_Info,G_Moudles_Config,G_STT_Run_Fun);
            base_moudle->reg_fun(-1,G_STT_Interpreter[-1]);
            base_moudle->reg_ui_fun(G_Reg_UI_FUN);
            i++;
            emit STT_Global::fl->signal_process(20+ 80 * i / plugindir.entryList(QDir::Files).size());
        }
    }
