Hi,

I'd like to replicate the PLINE grip menu on my custom entity : when grip is hovered, a menu is displayed (actions = Stretch Vertex, Add Vertex, Remove Vertex).

For now, I can display a context menu by:

1. creating a AcDbGripData (in subMoveGripPointsAt method)
2. Specifying a custom GripOperation (function ptr) for hover
3. Creating a CMenu in my custom GripOperation function
4. Displaying my menu like this : 

   BOOL result = pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_NONOTIFY | TPM_RETURNCMD, p.x + 15, p.y + 20, AfxGetMainWnd());

   (where p is a POINT representing the current cursor location)

I don't know if this is the right way because the point of the grip is blue (as if it was warm), while for the PLINE it becomes orange (see the image above).

And I like to know how to begin move grip process? The PLINE menu launches the command GRIP_STRETCH. I tried to use the same command but I was unable to execute it with:

acedCommand(RTSTR, _T("_.grip_stretch"), RTENAME, pickSet, RTNONE);

Maybe someone can provide an example? All suggestions are welcomed.

Regards,

Jonathan

Check out the class AcDbMultiModesGripPE class in dbMultiModesGrip.h in the ObjectARX SDK

Thank you for your answer. It could be a good solution, but I'm using OARX 2010 and I guess AcDbMultiModesGripPE appeared in OARX 2012 or 2013. Is there another solution or it's only a new feature of next OARX?

Hello,

The API for multi-functional grips was introduced in ObjectARX 2012 although AutoCAD had it as a feature in 2011.

Sorry, there is no way to get it using 2010 SDK.

Ok. Thank you for your anwser. I was able to reproduce this feature with a little time and perseverance.
