---------
I am able to add a layer to the layer browser through the following code:

  
  
 LayerObject *layer = NULL;  
   layer = LayerObject::Alloc();  
   if (!layer) return FALSE;  
  
   GeListHead *layerlist = NULL;  
   layerlist = doc->GetLayerObjectRoot();  
   if (!layerlist) return FALSE;  
  
  layer->SetName("My TEST Layer");  
  
   layerlist->Insert(layer, NULL, NULL);  
  
   layerlist->Message(MSG_UPDATE);

Now I would like to add various objects from my plugin to that layer. I tried doing

  
  
myObject->SetLayerObject(layer);

but it doesn't seem to work.

Any ideas on how to do this?

Thanks,

~Shawn

Not sure what's going wrong there. Here it's working.

My code:

  
Bool MenuTest::Execute(BaseDocument *doc)  
{  
  BaseObject *op = NULL;  
  op = doc->GetActiveObject();  
  if (!op) return FALSE;  
  
  GeListHead *layerlist = NULL;  
  layerlist = doc->GetLayerObjectRoot();  
  if (!layerlist) return FALSE;  
  
  LayerObject *layer = NULL;  
  layer = LayerObject::Alloc();  
  if (!layer) return FALSE;  
  
  layerlist->Insert(layer, NULL, NULL);  
  layer->Message(MSG_UPDATE);  
  
  if (!op->SetLayerObject(layer)) return FALSE;  
  op->Message(MSG_UPDATE);  
  
  EventAdd();  
  
  return TRUE;  
}

cheers,

Well the only difference between my code and yours is that my LayerObject is a member variable and is initialized in Init() then the call to add an object to that l layer is in a different function...

Do you think think that this is the reason it is not working?

Thanks,

As long as you make sure the layer object is valid and inserted into the layer list there shouldn't be a problem.
