Hello,

I want to read out all Layers from the Layer Manager. Also I want to add new layers, remove and rename. I found the LayerSet in the SDK: https://developers.maxon.net/docs/cpp/2023_2/class_layer_set.html#afc9ab69643027a912262c285c59e2be8

But I don't know how to use it? Does someone has an example for me?

thanks

No code but LayerData is where you want to begin. You can get the root layer (a list head) of the Document using BaseDocument::GetLayerObjectRoot(). Search here for GetLayerObjectRoot for some topics and code.

Thank You,

I figured out how it works:

  
      GeListHead* layerList = NULL;  
      layerList = doc->GetLayerObjectRoot();      
      LayerObject *layer = (LayerObject* )layerList->GetFirst();   //Get the first layer  
      const LayerData *data = layer->GetLayerData(doc, FALSE);    //Get the layer's container   
        
  
      while (layer) {  
          GePrint(layer->GetName());  
          layer = layer->GetNext();  
      }

Hello,

Layers are not just stored in a list but actually in a tree. So to get all layers you also need to check the child layers with GetDown().
