  [INIT_STATE s;]
  [IMAGE_n_ON|OFF id;]
  [ACCEPT idlist;]
  [REFUSE idlist;]
}

Description

Represents InExcludeData objects in a container, rendered as a drop area for objects.
Specify what kinds of nodes are accepted and/or refused for this field with ACCEPT and/or REFUSE.

Optionally the dropped objects get up to 32 icons next to them, each with an on/off state.

Note

The IDs used for the icons must be registered with RegisterIcon().

Further specify what objects are accepted by listening for MSG_DESCRIPTION_CHECKDRAGANDDROP in NodeData::Message() and returning true of false depending on the DescriptionCheckDragAndDrop data:

SplineRailObject::Message(GeListNode *node, Int32 type, void *data)
{
  ...
  if (type==MSG_DESCRIPTION_CHECKDRAGANDDROP)
  {
    DescriptionCheckDragAndDrop *dcu = static_cast<DescriptionCheckDragAndDrop*>(data);
    switch (dcu->id[0].id)
    {
      case SPLINERAILOBJECT_SPLINE1:
      case SPLINERAILOBJECT_SPLINE2:
      case SPLINERAILOBJECT_SPLINE3:
      case SPLINERAILOBJECT_SPLINE4:
      dcu->result = dcu->element->GetInfo() & OBJECT_SPLINE;
        return true;
      }
  }
}
