-There may be situations where customPaint() does not suit your needs. This can be the case when you don't want to paint at the very top position (above all other items), or when subclassing MarbleWidget is not possible for some reason. In that case, have a look at [[Projects/Marble/LayerInterface|Tutorial 2b - Creating Custom Layers]]
