AcedGrRead

[Anonymous]

I'm develop a run-time routine in arx using acedGrRead to get user
coordinate.

If the user want to zoom or use another autocad command, I get the code 11,
but I don't know what I must do to let Autocad execute the new command and
then resume my command.
This is the code:

void test()
{

int retType;
int pippo;
int track;
AcDbObjectId IdLine;
AcDbObjectId IdPrecLine;
resbuf *result = new resbuf();
MSG mes;
AcDbEntity *MyLine;

Acad::ErrorStatus
es=acDocManager->lockDocument(curDoc(),AcAp::kWrite,NULL,NULL,true);

IdPrecLine=AcDbObjectId();

do {

pippo=acedGrRead(3,&retType,result);

switch (retType)
{
case 5:
// Arrivata una cordinata
// faccio disegnare una linea da (0,0) al cursore

IdLine=DrawLine(0,0,0,result->resval.rpoint[0],result->resval.rpoint[1],0);

if(::PeekMessage(&mes, NULL, 0, 0, PM_REMOVE))
{
::TranslateMessage(&mes);
::DispatchMessage(&mes);
}

if (IdPrecLine!=0) {
acdbOpenObject(MyLine,IdPrecLine,AcDb::kForWrite);

MyLine->erase(true);
MyLine->close();

break;
}
case 11:
// what I must do here????

break;
}
IdPrecLine=IdLine;


if(::PeekMessage(&mes, NULL, 0, 0, PM_REMOVE))
{
::TranslateMessage(&mes);
::DispatchMessage(&mes);
}
} while (retType!=3);

es=acDocManager->unlockDocument(curDoc());

}

Thanks in advance!!!!

Marco: This is not going to work. Long ago I tried this and found it
virtually impossible to figure out what the codes mean for menu picks and
also deal with keyboard input. To make matters worse, object snap is
disabled while using acedGrRead().

I would strongly consider abandoning this and using AcEdJig or the
AcEdInputPointMonitor class (the latter is also complicated when transparent
commands are used).

I had been using the InputManager from AcadX.arx, but found that it would
get confused when transparent commands were invoked. That forced me to
resort to ObjectARX and the AcEdJig.

Dynamic graphics in AutoCAD is no day at the beach, even in ObjectARX.
