Top level component

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

QML top level type can't be 组件

What happened?

You used the 组件 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.

范例

import QtQuick
Component {
    Item { ... }
}

To fix this warning, remove the extra Component wrapping:

import QtQuick
Item { ... }
