# 01: hello bar

A `PanelWindow` can be the root object of `shell.qml`.
This example anchors one 30-pixel panel to the top edge and renders centered text.

Static check:

```sh
qmllint -I /usr/lib/qt6/qml examples/01-hello-bar/shell.qml
```

Do not launch it on the real desktop merely to validate the skill.
Mapped placement and appearance require separate visual acceptance in a nested compositor or explicitly approved session.
