This page will walk you through the process of creating a simple bar/panel, and
|

introduce you to all the basic concepts involved.

introduce you to all the basic concepts involved. You can use the
|
||||
[QML Language Reference](/docs/guide/qml-language) to learn about the syntax
|
||||
of the QML language.
|
||||
|
||||
There are many links to the [QML Overview](/docs/guide/qml-language)
|
||||
and [Type Reference](/docs/types) which you should follow if you don't
|
||||
fully understand the concepts involved.

Note that all the <a>Green Links</a> in code blocks will take you to the documentation

for their respective types.

## Shell Files
|
||||
## Config Files
|
||||
Quickshell searches the `quickshell` subfolder of every XDG standard config path
|
||||
for configs. Usually this is `~/.config/quickshell`.
|
||||
|
||||
Every quickshell instance starts from a shell root file, conventionally named `shell.qml`.
|
||||
The default path is `~/.config/quickshell/shell.qml`.
|
||||
(where `~/.config` can be substituted with `$XDG_CONFIG_HOME` if present.)
|
||||
Each named subfolder containing a `shell.qml` file is considered to be a config.
|
||||
If the base `quickshell` folder contains a shell.qml file, subfolders will not be
|
||||
considered.
|
||||
|
||||
Each shell file starts with the shell root object. Only one may exist per configuration.
|
||||
A specific config can be picked using the `--config` or `-c` argument to Quickshell.
|
||||
|
||||
```qml
|
||||
// ~/.config/quickshell/shell.qml
|
||||
import Quickshell
|
||||
|
||||
@@Quickshell.ShellRoot {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
The shell root is not a visual element but instead contains all of the visual
|
||||
and non visual objects in your shell. You can have multiple different shells
|
||||
with shared components and different shell roots.
|
||||
Configs at other paths, including raw qml files can be run with `--path` or `-p`.

## JavaScript APIs
|
||||
## Quickshell Support Libraries
|
||||
In addition to calling external processes, Quickshell comes with a large set of support libraries
|
||||
for common OS integrations and tasks. These libraries are indexed on the left sidebar.
|
||||
|
||||
In addition to calling external processes, a [limited set of javascript interfaces] is available.
|
||||
We can use this to improve our clock by using the [Date API] instead of calling `date`.
|
||||
One of these integrations is @@Quickshell.SystemClock, which exposes the system time in an easy to
|
||||
use way.
|
||||
|
||||
[limited set of javascript interfaces]: https://doc.qt.io/qt-6/qtqml-javascript-functionlist.html
|
||||
[Date API]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date
|
||||
We can use @@Quickshell.SystemClock.date to get a Date object to display. The
|
||||
@@QtQml.Qt.formatDateTime() function can be used to easily format the date
|
||||
as shown below.
|
||||
|
||||
@@Quickshell.SystemClock.precision can be set to `Minutes` to improve battery life if you don't
|
||||
show seconds on your clock, as Quickshell will have less work to do.
