动态创建右键快捷菜单

橡皮

右键菜单分两种：
1. acedAddDefaultContextMenu(
    AcEdUIContext * pContext,     const void * appId,     const ACHAR* appName = NULL
);添加默认模式快捷菜单，如CAD中的平移、缩放和快速选择等；
2. Adesk::Boolean acedAddObjectContextMenu(
    AcRxClass * pClass,     AcEdUIContext * pContext,     const void * appId);为给定的类添加编辑模式快捷菜单，如选中多段线之后的添加交点，选择Table之后设置表格样式等。
创建过程如下（先通过项目模板创建项目）:

1. // 定义控件 ID ，可以通过添加 Menu 资源的形式创建（这里不进行演示）也可以动态创建 Menu 的形式创建
   
2. #define IDC_ITEM_CreateCircle 1000
   
3. #define IDC_ITEM_Message 1001
   
4. #define IDC_ITEM_SetColor 1002
   
5. 
   
6. class MyAcEdUIContext : public AcEdUIContext
   
7. {
   
8. public:
   
9.   MyAcEdUIContext();
   
10.   ~MyAcEdUIContext();
    
11. 
    
12.   virtual void* getMenuContext(const AcRxClass* pClass, const AcDbObjectIdArray& ids);
    
13.   virtual void onCommand(Adesk::UInt32 cmdIndex);
    
14.   //virtual void OnUpdateMenu();
    
15. 
    
16. private:
    
17.   CMenu* m_pMenu;
    
18.   HMENU    m_hMenu;
    
19. };
    
20. 
    
21. MyAcEdUIContext::MyAcEdUIContext()
    
22. {
    
23.   m_pMenu = new CMenu();
    
24.   m_pMenu->CreatePopupMenu();
    
25.   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_CreateCircle, _T("创建圆"));
    
26.   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_Message, _T("Message"));
    
27.   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_SetColor, _T("设置颜色"));
    
28.   
    
29. }
    
30. 
    
31. MyAcEdUIContext::~MyAcEdUIContext()
    
32. {
    
33.   if (m_pMenu)
    
34.   {
    
35.     m_pMenu->DestroyMenu();
    
36.     delete m_pMenu;
    
37.   }
    
38. }
    
39. 
    
40. void* MyAcEdUIContext::getMenuContext(const AcRxClass* pClass, const AcDbObjectIdArray& ids)
    
41. {
    
42.   m_hMenu = m_pMenu->GetSafeHmenu();
    
43.   return &m_hMenu;
    
44. }
    
45. 
    
46. void MyAcEdUIContext::onCommand(Adesk::UInt32 cmdIndex)
    
47. {
    
48.   switch (cmdIndex)
    
49.   {
    
50.   case IDC_ITEM_CreateCircle:
    
51.     // 执行导入数据的操作
    
52.     acutPrintf(_T("\nIDC_ITEM_CreateCircle\n"));
    
53.     break;
    
54.   case IDC_ITEM_Message:
    
55.     // 执行导出数据的操作
    
56.     AfxMessageBox(_T("\nIDC_ITEM_Message\n"));
    
57.     break;
    
58.   case IDC_ITEM_SetColor:
    
59.     // 执行设置颜色的操作
    
60.     acutPrintf(_T("\nIDC_ITEM_SetColor\n"));
    
61.     break;
    
62.   default:
    
63.     break;
    
64.   }
    
65. }
    

// 定义控件 ID ，可以通过添加 Menu 资源的形式创建（这里不进行演示）也可以动态创建 Menu 的形式创建<br /> #define IDC_ITEM_CreateCircle 1000<br /> #define IDC_ITEM_Message 1001<br /> #define IDC_ITEM_SetColor 1002<br /> <br /> class MyAcEdUIContext : public AcEdUIContext<br /> {<br /> public:<br />   MyAcEdUIContext();<br />   ~MyAcEdUIContext();<br /> <br />   virtual void* getMenuContext(const AcRxClass* pClass, const AcDbObjectIdArray& ids);<br />   virtual void onCommand(Adesk::UInt32 cmdIndex);<br />   //virtual void OnUpdateMenu();<br /> <br /> private:<br />   CMenu* m_pMenu;<br />   HMENU    m_hMenu;<br /> };<br /> <br /> MyAcEdUIContext::MyAcEdUIContext()<br /> {<br />   m_pMenu = new CMenu();<br />   m_pMenu->CreatePopupMenu();<br />   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_CreateCircle, _T("创建圆"));<br />   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_Message, _T("Message"));<br />   m_pMenu->AppendMenu(MF_STRING, IDC_ITEM_SetColor, _T("设置颜色"));<br />   <br /> }<br /> <br /> MyAcEdUIContext::~MyAcEdUIContext()<br /> {<br />   if (m_pMenu)<br />   {<br />     m_pMenu->DestroyMenu();<br />     delete m_pMenu;<br />   }<br /> }<br /> <br /> void* MyAcEdUIContext::getMenuContext(const AcRxClass* pClass, const AcDbObjectIdArray& ids)<br /> {<br />   m_hMenu = m_pMenu->GetSafeHmenu();<br />   return &m_hMenu;<br /> }<br /> <br /> void MyAcEdUIContext::onCommand(Adesk::UInt32 cmdIndex)<br /> {<br />   switch (cmdIndex)<br />   {<br />   case IDC_ITEM_CreateCircle:<br />     // 执行导入数据的操作<br />     acutPrintf(_T("\nIDC_ITEM_CreateCircle\n"));<br />     break;<br />   case IDC_ITEM_Message:<br />     // 执行导出数据的操作<br />     AfxMessageBox(_T("\nIDC_ITEM_Message\n"));<br />     break;<br />   case IDC_ITEM_SetColor:<br />     // 执行设置颜色的操作<br />     acutPrintf(_T("\nIDC_ITEM_SetColor\n"));<br />     break;<br />   default:<br />     break;<br />   }<br /> }<br />

使用过程如下：

1. MyAcEdUIContext* pMyContextMenu = nullptr;
   
2. MyAcEdUIContext* pObjMenu = nullptr;
   
3. 
   
4.   // 创建
   
5.   virtual AcRx::AppRetCode On_kInitAppMsg (void *pkt) {
   
6.     // TODO: Load dependencies here
   
7. 
   
8.     // You *must* call On_kInitAppMsg here
   
9.     AcRx::AppRetCode retCode =AcRxArxApp::On_kInitAppMsg (pkt) ;
   
10.    
    
11.     PrintCopyRightInfo();
    
12. 
    
13.     pMyContextMenu = new MyAcEdUIContext();
    
14.     auto rt = acedAddDefaultContextMenu(pMyContextMenu, pkt, _T("MenuDemo"));
    
15.     if (rt == Adesk::kFalse)
    
16.     {
    
17.       delete pMyContextMenu;
    
18.       pMyContextMenu = nullptr;
    
19.     }
    
20. 
    
21.     pObjMenu = new MyAcEdUIContext();
    
22.     auto rt2 = acedAddObjectContextMenu(AcDbTable::desc(), pObjMenu, pkt);
    
23.     if (rt2 == Adesk::kFalse)
    
24.     {
    
25.       delete pObjMenu;
    
26.       pObjMenu = nullptr;
    
27.     }
    
28. 
    
29.     // TODO: Add your initialization code here
    
30. 
    
31.     return (retCode) ;
    
32.   }
    
33. 
    
34.   // 卸载
    
35.   virtual AcRx::AppRetCode On_kUnloadAppMsg (void *pkt) {
    
36.     // TODO: Add your code here
    
37.     if (pMyContextMenu)
    
38.     {
    
39.       acedRemoveDefaultContextMenu(pMyContextMenu);
    
40.       delete pMyContextMenu;
    
41.     }
    
42. 
    
43.     if (pObjMenu)
    
44.     {
    
45.       acedRemoveObjectContextMenu(AcDbTable::desc(), pObjMenu);
    
46.       delete pObjMenu;
    
47.     }
    
48. 
    
49.     // You *must* call On_kUnloadAppMsg here
    
50.     AcRx::AppRetCode retCode =AcRxArxApp::On_kUnloadAppMsg (pkt) ;
    
51. 
    
52.     // TODO: Unload dependencies here
    
53. 
    
54.     return (retCode) ;
    
55.   }

MyAcEdUIContext* pMyContextMenu = nullptr;<br /> MyAcEdUIContext* pObjMenu = nullptr;<br /> <br />   // 创建<br />   virtual AcRx::AppRetCode On_kInitAppMsg (void *pkt) {<br />     // TODO: Load dependencies here<br /> <br />     // You *must* call On_kInitAppMsg here<br />     AcRx::AppRetCode retCode =AcRxArxApp::On_kInitAppMsg (pkt) ;<br />     <br />     PrintCopyRightInfo();<br /> <br />     pMyContextMenu = new MyAcEdUIContext();<br />     auto rt = acedAddDefaultContextMenu(pMyContextMenu, pkt, _T("MenuDemo"));<br />     if (rt == Adesk::kFalse)<br />     {<br />       delete pMyContextMenu;<br />       pMyContextMenu = nullptr;<br />     }<br /> <br />     pObjMenu = new MyAcEdUIContext();<br />     auto rt2 = acedAddObjectContextMenu(AcDbTable::desc(), pObjMenu, pkt);<br />     if (rt2 == Adesk::kFalse)<br />     {<br />       delete pObjMenu;<br />       pObjMenu = nullptr;<br />     }<br /> <br />     // TODO: Add your initialization code here<br /> <br />     return (retCode) ;<br />   }<br /> <br />   // 卸载<br />   virtual AcRx::AppRetCode On_kUnloadAppMsg (void *pkt) {<br />     // TODO: Add your code here<br />     if (pMyContextMenu)<br />     {<br />       acedRemoveDefaultContextMenu(pMyContextMenu);<br />       delete pMyContextMenu;<br />     }<br /> <br />     if (pObjMenu)<br />     {<br />       acedRemoveObjectContextMenu(AcDbTable::desc(), pObjMenu);<br />       delete pObjMenu;<br />     }<br /> <br />     // You *must* call On_kUnloadAppMsg here<br />     AcRx::AppRetCode retCode =AcRxArxApp::On_kUnloadAppMsg (pkt) ;<br /> <br />     // TODO: Unload dependencies here<br /> <br />     return (retCode) ;<br />   }

效果如下：

添加的代码为啥总是保存不上啊！！！

谢谢分享，可惜CAD自身的右键菜单已经有些臃肿不堪
