`surface`

group surface: node

What every surface accepts.

Also every prop and event of node.

Prop	Type
`screens`	`Screens \| [text] \| text`	The monitors it is on: `all`, `focused`, or output names.
`layer`	`Layer`	Its layer-shell layer.
`open`	`<-> bool`	Whether it is shown. Bound two-way (`open: <-> open`), Escape, click-away and focus loss write false; on a `window` only the compositor's close and `w.close()` do.
`keyboard`	`Keyboard`	Keyboard focus: `none`, `on_demand` or `exclusive`.
`anchor`	`Anchor`	Where it sits on the screen: `anchor: top_right`.
`attach`	`Edge`	Grows out of an edge with concave fillets: `attach: top`.
`scrim`	`color`	A colour dimming what is behind it, on a `popup` or `panel`: `scrim: $shadow.alpha(0.3)`. A single-pixel buffer, so it costs nothing; a gradient has no single-pixel form.
`inhibit_idle`	`bool`	While it is shown, the compositor does not go idle (no screensaver, dimming or lock by timeout): `bar Top { inhibit_idle: caffeine }`.

Event
`on show`	It was shown: `on show { query = "" }`.
`on hide`	It was hidden.
