JFrame（改进扩展点和扩展实现）

首先看看配置文件的改动：

{     "Extension": [         {             "ExtensionPoint": {                 "pointName": "Logger",                 "pointIcon": "./images/plane.png"             },             "ExtensionImpl": {                 "pluginName": "JLogger",                 "widgetName": "LoggerPanel"             }         },         {             "ExtensionPoint": {                 "pointName": "Test",                 "pointIcon": "./images/config.png"             },             "ExtensionImpl": {                 "pluginName": "TestPlugin",                 "widgetName": "Widget"             }         }     ] }

配置文件中，加入了 widgetName ，这样的话具体到了一个扩展点的实现是由具体的一个插件里面的widget！   同样很大的改动是扩展实现的逻辑是由 ActionManager 来实现，而不是由负责扩展点实现的插件来负担！

 1 void ActionManager::slotTriggered(QString _aName)
 2 {
 3     auto _it = m_actionExtensionMap.begin();
 4     for(;_it!= m_actionExtensionMap.end(); _it++)
 5     {
 6         if(_it->first.pointName == _aName)
 7         {
 8             break;
 9         }
10     }
11 
12     std::shared_ptr<QWidget> _widget;
13     if(_it == m_actionExtensionMap.end())
14     {
15         return;
16     }
17     _widget = _it->second.widget;
18 
19     if(_widget.get())
20     {
21         if(m_mainWindow->centralWidget() != _widget.get())
22         {
23             JLogger::INFO(QString("[ %1 ] 窗体被加入到 centeralWidget！").arg(_widget->objectName()));
24             m_mainWindow->takeCentralWidget();
25             m_mainWindow->setCentralWidget(_widget.get());
26         }
27     }
28 }
