# desktop

One drawer, left of DP-1, hosting the things a desktop lets you adjust.
Reached from a launcher at the left end of waybar.

The drawer opens as a grid of tiles, and clicking a tile either opens that
module's page or fires an action. A module's back arrow, and Escape while a
page is showing, return to the grid; Escape on the grid, or a click outside,
closes the drawer. It takes keyboard focus while it is open, so those keys
reach it.

## Running it

    qs -p ./desktop

    qs -p ./desktop ipc call drawer toggle      # the grid
    qs -p ./desktop ipc call drawer open mail   # straight to a page

`open` always takes a page name, because quickshell 0.3.1 IPC requires every
declared argument to be present and a defaulted parameter registers as a type
the IPC layer rejects. The page-less grid entry is therefore the zero-argument
`toggle`. `ipc call drawer close` closes it.

## The modules

    modules/sound/       output and input volume, the OSD, the player
    modules/network/     wired and wifi, radio, scan, join, forget
    modules/bluetooth/   adapter, scan, pair, connect, forget, trust
    modules/mail/        unread per account, threads, the watcher dot
    modules/vm/          libvirt state, live stats, snapshots
    modules/appearance/  a tile that opens the separate appearance shell

Sound, mail, vm, network and bluetooth each carry their own README. Appearance
is a tile onto the separate appearance shell, whose README covers the picker
it opens.

## Writing a module

A module is a `Module` (from `Module.qml` in this directory) declaring what the
drawer needs to show it:

- `name`: identifies the module, both for grid ordering and for IPC, where it
  is the page name `ipc call drawer open <name>` takes.
- `icon` and `label`: the glyph and the text on the tile.
- `tileContent`: a `Component` for the short state line under the label, or
  null for a tile that says nothing beyond its name.
- `page`: a `Component` for the full-height page behind the tile, or null.
- `activate()`: what a tile with no page does when clicked.
- `alwaysActive`: declares whether the module's service is meant to run while
  the drawer is closed. The drawer does not read it, the module implements its
  own lifetime. Covered below.

A module provides a tile, a page, both, or neither. The drawer does not care
which: it reads those properties and does the obvious thing. A page is wrapped
in `Page.qml` for the header and back arrow, and a tile with no page is
fire-and-forget, so its click calls `activate()` and closes the drawer.

`modules/appearance/AppearanceModule.qml` is the smallest complete example: a
name, an icon, a label, and an `activate()` that launches the separate
appearance shell. It has no page, and it owns only a `Process` that fires the
picker on click, no always-active service. Sound, mail, vm, network and
bluetooth each add a service and a page on top of that same shape.

Module files live under `desktop/modules/<name>/` and reference root types
(`Module`, `Page`, `Button`, `Theme`), so each needs `import "../.."`. A plain
directory import does not reach the parent. The moved `TransportButton.qml` and
`Stat.qml` gained that import for the same reason.

## alwaysActive

`alwaysActive` is declarative metadata: it documents whether a module's service
is meant to run while the drawer is closed. The drawer does not read or enforce
it. Each module implements its own service lifetime, and the property records
that choice rather than driving it. Sound, mail, network and bluetooth are
`alwaysActive: true`; vm is false.

Sound's OSD has to answer a volume keypress with no drawer open, which is the
whole point of it, so its PipeWire service is instantiated eagerly and runs for
the session. Mail's unread count outlives the drawer and its config watcher
makes a newly added account appear without a restart, so its service is
instantiated eagerly too. The vm module's 2s stats poll exists only to paint a
page nobody is looking at, so it starts and stops with the page.

vm is not only its poll, however: its lifecycle event stream runs
unconditionally, which is what keeps the VM list and the tile's dots current
while the page is closed. Pages are lazily loaded in every module.

## Geometry

The panel is 600px wide and full height, on `DP-1`. Waybar runs there and the
launcher sits at its left end, while conky holds the right side of the screen,
so the drawer belongs on the left. It falls back to the first screen when
`DP-1` is not connected, so the drawer is never invisible.

The window uses `ExclusionMode.Normal`, not `Ignore`. Waybar claims an
exclusive zone at the top of the screen, so respecting it puts the drawer below
the bar without this code knowing the bar's height, and the bar stays visible
and clickable while the drawer is open. The whole surface is an overlay so a
click outside closes it.

The top of the panel is an empty reserved area for the notification engine. It
is an empty `Item` claiming the space, not a placeholder graphic, so the grid
below it sits where it will sit once notifications arrive. The bottom is a
fixed, never-scrolled `Flow` grid: three columns at 180px minimum, wrapping
and adding rows up to a 3x3 ceiling for the modules that exist, in the order
Sound, Network, Bluetooth, Mail, Appearance, Machines.

## Hyprland and waybar

Nothing here is in the repo's control, and the drawer works without it. Two
pieces of outside configuration belong to it.

Frosting is the compositor's, matched on the namespace this window sets. The
drawer sets `quickshell-desktop`, so it needs:

    hl.layer_rule({
        name         = "blur-desktop",
        match        = { namespace = "^(quickshell-desktop)$" },
        blur         = true,
        xray         = false,
        ignore_alpha = 0.1,
    })

The sound module's OSD owns its own window and keeps its old
`quickshell-volume-osd` namespace, so the existing `blur-volume-osd` rule still
matches and stays. Without any of these the surfaces still render, just flat
translucent.

The waybar launcher is a static `custom` module with no `exec`, so it cannot
show whether the drawer is open. Its `on-click` runs the zero-argument toggle:

    "on-click": "qs -p ~/Programming/GIT/quickshell/desktop ipc call drawer toggle"

The mail module's waybar count keeps its own `custom` module, whose click
deep-links to the mail page with `ipc call drawer open mail`. `SUPER+v` reaches
the vm page the same way, with `ipc call drawer open vm`. The full list of
edits to the live Hyprland and waybar configuration is Task 10 of the plan in
`docs/superpowers/plans/2026-09-14-desktop-shell.md`.

The drawer is the only place network and Bluetooth are managed, so waybar's
own network and Bluetooth indicators were removed in the same change.

## Theme

`Theme.qml` is a symlink to `shared/Theme.qml`, as in every component here.
