在AUTOCAD 2015 使用3DPOLY命令中使用回调的代码

LoveArx

回调函数是myTest3DPolyCallback， 主命令函数是MyGroupTestSendCommand3

static int myTest3DPolyCallback(void *pData)
{
        if (acedCmdCWasCancelled())
        {
                acutPrintf(_T("\n3DPoly Command was cancelled..."));
                return 0;
        }
        if (is3DPolyActive())
        {
                int res = acedCommandC(&myTest3DPolyCallback, NULL, RTSTR, PAUSE, RTNONE);
                acedCallBackOnCancel();
                acutPrintf(_T("\nmyTest3DPolyCallback: 3DPoly is active. res=%d"), res);
                return 1;
        }
        CallWhen3DPolyDone();
        return 0;
}

static Adesk::Boolean is3DPolyActive()
{
        struct resbuf rb;
        acedGetVar(_T("CMDNAMES"), &rb);
        if (_tcsstr(rb.resval.rstring, _T("3DPOLY")))
                return Adesk::kTrue;
        return Adesk::kFalse;
}

static void CallWhen3DPolyDone()
{
        acutPrintf(_T("\n3DPoly Command completed..."));
}

static void MyGroupTestSendCommand3(void)
{
        acedCommandC(&myTest3DPolyCallback, NULL, RTSTR, _T("_.3DPOLY"), RTSTR, PAUSE, RTSTR, PAUSE, RTNONE);
        acutPrintf(ACRX_T("\nAfter acedCommandC call. acedCommandC is asynchronous..."));
}
