[讨论]关于自定义双击
[讨论]关于自定义双击
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
#pragma once
#include "acdblclkedit.h"
#include "bclpro.h"
class bclclk :
public acdbdoubleclickedit
{
public:
bclclk(void);
virtual ~bclclk(void);
public:
virtual void startedit(acdbentity *pent, acgepoint3d pt);
virtual void finishedit();
};
类的实现:

#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?
