\title Top level component
\brief [top-level-component] Root QML type is a component
 
\qmllintwarningcategory top-level-component
 
\section1 QML top level type can't be \e Component
 
\section2 What happened?
You used the \l [QML] {Component} type as top level type for your
QML file.
 
\section2 Why is this bad?
Your QML file already defines a component by itself. Using a \c Component type as
a top level type will wrap your component into another unnecessary component.
 
\section2 Example
\qml
import QtQuick
 
Component {
    Item { ... }
}
\endqml
To fix this warning, remove the extra Component wrapping:
\qml
import QtQuick
 
Item { ... }
\endqml
