Howdy,

My tag has Add and Delete buttons, so I need to create vector attributes in GetDDescription() according to how many the user has added.

My code looks like this:

BaseContainer subgroup2 = GetCustomDataTypeDefault(DTYPE_GROUP);
subgroup2.SetLong(DESC_COLUMNS, 1);
if(!description->SetParameter(DescLevel(OFFSET_GROUP+i, DTYPE_GROUP, 0), subgroup2, DescLevel(ID_TARGET_GROUP))) return TRUE;
		
BaseContainer bc4 = GetCustomDataTypeDefault(DTYPE_VECTOR);
bc4.SetLong(DESC_CUSTOMGUI,CUSTOMGUI_VECTOR);
bc4.SetString(DESC_NAME, GeLoadString(IDS_OFFSET)+"."+LongToString(i));
bc4.SetLong(DESC_UNIT, DESC_UNIT_DEGREE);
bc4.SetReal(DESC_STEP,Rad(1.0));
if (!description->SetParameter(DescLevel(OFFSET+i, DTYPE_VECTOR, 0), bc4, DescLevel(OFFSET_GROUP+i))) return TRUE;

This is within a loop and it does create the vector attributes needed with each click of the Add button, but the up/down arrows of each value field aren't working. I can change the values by typing them in, but I can't use the up/down arrows to change the values.

Is there something missing in the above code thats causing the up/down arrows to not work?

Adios,
Cactus Dan

Looks like the step setting has to be set separatly for each sub-channel of the vector. I will try to put a working example together, having some problems to get it to work properly too.

cheers,

The solution is to use SetVector instead of SetReal to set the step size and minimum/maximum values.

Example:

  
Bool LookAtCamera::GetDDescription(GeListNode *node, Description *description, DESCFLAGS_DESC &flags)  
{  
  if (!description->LoadDescription(1001165)) return FALSE;  
  const DescID *singleid = description->GetSingleDescID();  
  
  LONG MY_VECTOR = 6000;  
  DescID cid = DescLevel(MY_VECTOR, DTYPE_VECTOR, 0);  
  
  if (!singleid || cid.IsPartOf(*singleid, NULL)) // important to check for speedup c4d!  
  {  
      BaseContainer v = GetCustomDataTypeDefault(DTYPE_VECTOR);  
  
      v.SetLong(DESC_CUSTOMGUI, CUSTOMGUI_VECTOR);  
      v.SetString(DESC_NAME, "My Vector");  
  
      // use SetVector, not SetReal  
      v.SetVector(DESC_MIN, Vector(0.0));  
      v.SetVector(DESC_MAX, Rad(360.0));  
      v.SetVector(DESC_STEP, Rad(1.0));  
  
      v.SetLong(DESC_UNIT, DESC_UNIT_DEGREE);  
      v.SetVector(DESC_DEFAULT, Vector(0.0));  
  
      if (!description->SetParameter(cid, v, DescLevel(ID_TAGPROPERTIES))) return TRUE;  
  }  
  
  flags |= DESCFLAGS_DESC_LOADED;  
  
  return TRUE;  
}

cheers,
