[讨论]关于自定义双击

7686599

在一个程序中,我定义了一个双击类.重载了 startEdit() 和 finishEdit() 函数. 但好像在程序结束后,要再运行一下任意一个命令才能结束这个双击. 请问是怎么回事?
这是类定义

1. #pragma once
2. #include "acdblclkedit.h"
3. #include "BclPro.h"
4. class BclClk :
5. public AcDbDoubleClickEdit
6. {
7. public:
8. BclClk(void);
9. virtual ~BclClk(void);
10. public:
11. virtual void startEdit(AcDbEntity *pEnt, AcGePoint3d pt);
12. virtual void finishEdit();
13. };

复制代码

类的实现:

2. #include "StdAfx.h"
3. #include "BclClk.h"
4. #include "FrmMain.h"
5. BclClk::BclClk(void)
6. {
7. }
8. BclClk::~BclClk(void)
9. {
10. }
11. void BclClk::startEdit(AcDbEntity *pEnt, AcGePoint3d pt)
12. {
13. acDocManager->lockDocument(curDoc());
14. if (pEnt->isKindOf(BclSub::desc()) == Adesk::kTrue)
15. {
16.   BclSub *pEntity = BclSub::cast(pEnt);
17.   if (pEntity->upgradeOpen() == Acad::eOk)
18.   {
19.    CAcModuleResourceOverride resoverrid;
20.    FrmMain *pMainFrm = new FrmMain(CWnd::FromHandle(adsw_acadMainWnd()));
21.    pMainFrm->setEntity(pEntity);
22.    pMainFrm->startDialog(pMainFrm, true);   
23.    if (pMainFrm)
24.    {
25.     delete pMainFrm;
26.     pMainFrm = NULL;
27.    }  
28.    pEntity->recordGraphicsModified();
29.    pEntity->close();
30.    pEntity->recordGraphicsModified();
31.   }
32. }
33. acDocManager->unlockDocument(curDoc());
34. acedUpdateDisplay();
35. finishEdit();
36. }
37. void BclClk::finishEdit()
38. {
39. acedSSSetFirst(NULL, NULL);
40. }

#include "StdAfx.h" #include "BclClk.h" #include "FrmMain.h" BclClk::BclClk(void) { } BclClk::~BclClk(void) { } void BclClk::startEdit(AcDbEntity *pEnt, AcGePoint3d pt) { acDocManager->lockDocument(curDoc()); if (pEnt->isKindOf(BclSub::desc()) == Adesk::kTrue) {   BclSub *pEntity = BclSub::cast(pEnt);   if (pEntity->upgradeOpen() == Acad::eOk)   {    CAcModuleResourceOverride resoverrid;    FrmMain *pMainFrm = new FrmMain(CWnd::FromHandle(adsw_acadMainWnd()));    pMainFrm->setEntity(pEntity);    pMainFrm->startDialog(pMainFrm, true);       if (pMainFrm)    {     delete pMainFrm;     pMainFrm = NULL;    }      pEntity->recordGraphicsModified();    pEntity->close();    pEntity->recordGraphicsModified();   } } acDocManager->unlockDocument(curDoc()); acedUpdateDisplay(); finishEdit(); } void BclClk::finishEdit() { acedSSSetFirst(NULL, NULL); }

现在这样做了之后,必须得任意运行一个命令才能结束双击,看到实体的修改变化.请问我应该如何做才能让它自动结束这个双击?
