AcGs question

Anonymous · ‎06-13-2002

Hello,

I have a modal dialog with a list. When I select a list item, I do the
following:

//------------------------------------------------------------------
m_pGSManager = acgsGetGsManager(acedGetAcadDwgView());
m_pGSDevice = m_pGSManager->getGUIDevice();
m_pGSView = m_pGSManager->getGSClassFactory()->createView();

resbuf wcs, ccs, dcs;

wcs.restype = RTSHORT;
wcs.resval.rint = 0;
ccs.restype = RTSHORT;
ccs.resval.rint = 1;
dcs.restype = RTSHORT;
dcs.resval.rint = 2;

resbuf rb,rbVMin,rbVMax;

AcGeVector3d viewDir;
AcGePoint3d cenPt,vsMin,vsMax;

acedGetVar("VSMIN", &rbVMin);
acedTrans(rbVMin.resval.rpoint, &ccs, &wcs, 0, asDblArray(vsMin));

acedGetVar("VSMAX", &rbVMax);
acedTrans(rbVMax.resval.rpoint, &ccs, &wcs, 0, asDblArray(vsMax));

cenPt = AcGeLineSeg3d(vsMin,vsMax).midPoint();

acedGetVar("VIEWDIR", &rb);
acedTrans(rb.resval.rpoint, &ccs, &wcs, 0, asDblArray(viewDir));

m_pGSView->setView(cenPt+viewDir,cenPt,viewDir,vsMax.x-vsMin.x,vsMax.y-vsMin
.y);

m_pConnectionMarker = new
AcDbBlockReference(AcGePoint3d::kOrigin,m_idOfConnectionMarkerBlock); //
m_idOfConnectionMarkerBlock is in the current dwg and valid
m_pConnectionMarker->setPosition(m_pListOfItems->connectionPoint(l_hItem));
// the point is on the screen. I'm sure.

m_pGSView->add(m_pConnectionMarker,m_pGSManager->getDBModel());
m_pGSDevice->add(m_pGSView);

m_pGSView->invalidateCachedViewportGeometry();
m_pGSView->invalidate();

m_pGSManager->getDBModel()->invalidate(AcGsModel::kInvalidateAll);
//------------------------------------------------------------------

The block not displayed.
How can I display a non-database resident entity (a drawable) using the GS
system?

The blockview sample doesn't help.
Any idea? Or a code snippet?

Thanx
Zé

Just a thought...
I would think you should use a jig, may be that's a bit out of the way but
only the jig is able to display non db-resident ents.
Otherwise you could temporarily add an entity - display it and then erase it
again.

No, it's not a jig.
I have a !! modal dialog !!. When the user selects an element, it zooms
(works fine) to that and
put a mark around that item on acad drawing area.
Now I have to insert a block and update its position.
Its working, but not an elegant solution (it unnecessarily modifies the dwg)

Unfortunately the GS system not well documented enough.
With the GS you can use a AcGsView (like the UCS icon or the orbit does)
to display a "drawable".

So I'm waiting for Autodesk, to give us just a litle bit deeper
documentation.
Or trying, trying, trying and getting balder and balder.

I have successfully added non-DBR entities to an AcGsView using the
following initialization:

m_Device = m_GsManager->createAutoCADDevice(m_hWnd);
// a simple view
m_View = m_GsFactory->createView();
// a model with open/close protocol
m_Model = m_GsManager->createAutoCADModel();
m_Device->add(m_View);

Easy on your scalp 🙂

I have successfully added non-DBR entities to an AcGsView using the
following initialization:

m_Device = m_GsManager->createAutoCADDevice(m_hWnd);
// a simple view
m_View = m_GsFactory->createView();
// a model with open/close protocol
m_Model = m_GsManager->createAutoCADModel();
m_Device->add(m_View);
