# Top level component

This warning category is spelled `[top-level-component]` by qmllint.

## QML top level type can't be Component

### What happened?

You used the Component type as top level type for your QML file.

### Why is this bad?

Your QML file already defines a component by itself. Using a `Component` type as a top level type will wrap your component into another unnecessary component.

### Example

     import QtQuick

     Component {
         Item { ... }
     }

To fix this warning, remove the extra Component wrapping:

     import QtQuick

     Item { ... }
