Drag from dialog - drop onto scene object

Rhino Developer

Hello

How I can implement in RhinoCommon dragging something from my dialog and dropping it onto some scene object?
and of cause process dropping somehow - i.e. assign some custom data to attributes

Sorry, no. But the older Rhino.NET SDK does via the RMA.Rhino.MRhinoDropTarget class.

Here is an example of its usage:

To use Rhino.NET in a RhinoCommon plug-in, just add a reference to Rhino_DotNet.dll, which is found in Rhino’s SYSTEM folder. Make sure to set the reference’s Copy Local property to False.

More on Rhino.NET:

Note, adding drag & drop support to RhinoCommon is on the V6 list.

It works:)

but how can I convert IRhinoObjRef here
OnDropOnObject(IRhinoObjRef objRef, MRhinoView rhinoView, DataObject data, DragDropEffects dropEffect, Point point)
to RhinoObject?

Instead of “converting”, you might just lookup the object by it’s runtime serial number.

For example:

void OnDropOnObject(
  IRhinoObjRef objRef, 
  MRhinoView rhinoView, 
  DataObject data, 
  DragDropEffects dropEffect, 
  Point point
  )
{
  IRhinoObject rh_obj = objRef.Object();
  if (null != rh_obj)
  {
    Rhino.RhinoDoc doc = Rhino.RhinoDoc.ActiveDoc;
    if (null != doc)
    {
      Rhino.DocObjects.RhinoObject obj = doc.Objects.Find(rh_obj.m_runtime_object_serial_number);
      if (null != obj)
      {
        // TODO...
      }
    }
  }
}
