Window is one materialized (session, index, window) winlink record. It is normally returned by [Server.Snapshot], [Server.Window], or [Window.Refresh]. A zero Window is not a usable tmux target.

## Members

- `DisplayMessage` (method) — DisplayMessage displays or prints a message at this window's exact target. Print returns an owned stdout slice even on a completed nonzero exit; completed stderr reaches [WarningHandler] as [WarningCommandStderr]. NoExpand follows [UnsupportedPolicy]. Warnings run synchronously before return; context cancellation does not prove display did not occur.
- `Formats` (method) — Formats returns this Window's read-only materialized tmux format values. It does not query tmux; use [Server.Snapshot] to obtain a fresh record.
- `Active` (method) — Active returns tmux #{window_active} as bool from this Window's materialized window-scoped fields (tmux 3.2a or later).
- `ActiveClients` (method) — ActiveClients returns tmux #{window_active_clients} as int from this Window's materialized window-scoped fields (tmux 3.2a or later).

- `ZoomedFlag` (method) — ZoomedFlag returns tmux #{window_zoomed_flag} as bool from this Window's materialized window-scoped fields (tmux 3.2a or later).
- `Hooks` (method) — Hooks returns a freshly decoded, caller-owned view of known hooks at this exact window target, including inherited values. The receiver's exact linked session context controls tmux format evaluation. A read failure is returned rather than answered with zero values.
- `RawHook` (method) — RawHook returns one exact window hook value at this exact window target. A successful string is caller-owned; the receiver's exact linked session context controls tmux format evaluation, and completed failures are returned.
- `SetHook` (method) — SetHook stores a window hook at this exact window target without refreshing models. Completed failures are secret-safe option errors; cancellation does not prove tmux did not accept the mutation.
- `AppendHook` (method) — AppendHook appends a window hook at this exact window target without refreshing models. Completed failures are secret-safe option errors; cancellation does not prove tmux did not accept the append.
- `UnsetHook` (method) — UnsetHook removes every matching window hook index at this exact window target without refreshing models. Completed failures are secret-safe option errors; cancellation does not prove the unset was accepted.
- `RunHook` (method) — RunHook asks tmux to run one window hook directly at this exact target. The receiver's exact linked session context controls tmux format evaluation; no racy preflight is issued. Completed failures are secret-safe option errors; cancellation does not prove execution did not occur.
- `SetHooks` (method) — SetHooks applies indexed window hook commands in ascending order at this handle's exact window target. With ClearExisting it confirms clearing first, stops at the first failure without rollback, and reports confirmed progress. Cancellation may follow accepted commands and cannot disprove their delivery.
- `Equal` (method) — Equal reports whether two window records carry the same stable window ID. It intentionally collapses linked-session views with different sessions or indexes; use SessionID, WindowID, and WindowIndex for exact view identity.
- `String` (method) — String returns the winlink identity and its materialized parent, when present.
- `Kill` (method) — Kill destroys the stable window selected by the receiver's WindowID, removes all of its winlinks, and destroys its panes. Affected sessions preserve their current selection unless this window was current, in which case they select another. A session left without windows is destroyed; [Session.Kill] describes how tmux handles its clients. The receiver is not refreshed. Only stderr makes a completed command a [CommandError]; nonzero exits without stderr are ignored.
- `KillOthers` (method) — KillOthers destroys every other stable window selected through the receiver's exact session and leaves the receiver as that session's current and only window. Links in other sessions are not selected merely because they share the receiver's [WindowID], but every selected stable window is removed from all sessions. Other affected sessions preserve their current selection unless a destroyed window was current, in which case they select another. A session left without windows is destroyed; [Session.Kill] describes how tmux handles its clients. The receiver is not refreshed. Only stderr makes a completed command a [CommandError]; nonzero exits without stderr are ignored.
- `Refresh` (method) — Refresh performs a canonical live lookup for the window's stable ID and returns a new record without mutating the receiver. It does not preserve a linked-session view; use [Window.ResolveSession] for exact relationships.
- `SessionID` (method) — SessionID returns the linked session containing this view.
- `ID` (method) — ID returns the underlying stable tmux window identity.
- `Index` (method) — Index returns this window's index in its linked session. It returns -1 for a partial Window whose exact winlink has not been materialized.
- `Server` (method) — Server returns the configured handle that produced the window.
- `Session` (method) — Session returns this view's parent record when it remains in the same snapshot. It never queries tmux.
- `Panes` (method) — Panes returns newly allocated shallow copies of panes for this exact winlink, and reports whether the receiver carries relations at all.

Replacement is not atomic: the result reports confirmed writes, and failures stop without rollback. Serialize concurrent replacement of the same target and option.
- `SetOption` (method) — SetOption stores a window option at this exact window target without refreshing existing models. Completed failures are secret-safe option errors; cancellation does not prove tmux did not accept the mutation.
- `AppendOption` (method) — AppendOption appends to a window option at this exact window target without refreshing models. Completed failures are secret-safe option errors; cancellation does not prove the append was not accepted.
- `UnsetOption` (method) — UnsetOption unsets a window option at this exact window target, or its pane copies with UnsetPanes, without refreshing models. Cancellation does not prove the unset was not accepted.
- `Options` (method) — Options returns a freshly decoded, caller-owned view of known options at this exact window target, including inherited values. The receiver's exact linked session context controls tmux format evaluation. A read failure is returned rather than answered with zero values. Each returned accessor names the setter that writes it, so [WindowOptionValues.MainPaneWidth] pairs with [Window.SetMainPaneWidth].
- `RawOption` (method) — RawOption returns one exact window option value at this exact window target. A successful string is caller-owned; the receiver's exact linked session context controls tmux format evaluation, and a completed failure is returned.
- `NewPane` (method) — NewPane creates a floating pane in the receiver's exact winlink. Attach makes the new pane active in that session and winlink; it is not a global client-focus guarantee. The returned [Pane] is freshly materialized in the receiver SessionID and WindowID rather than by canonical ID-only refresh.
- `SplitPane` (method) — SplitPane creates a tiled pane in the receiver's exact winlink. Attach makes the new pane active in that session and winlink; it is not a global client-focus guarantee. The returned [Pane] is freshly materialized in the receiver SessionID and WindowID rather than by canonical ID-only refresh.
- `Ref` (method) — Ref returns a [Ref] addressing the receiver.
- `ActivePane` (method) — ActivePane returns the first active pane in this materialized winlink view. It never queries tmux; use [Window.ResolveActivePane] for live state.
- `LinkedSessions` (method) — LinkedSessions returns newly allocated shallow copies of materialized sessions containing this window, and reports whether the receiver carries relations at all. It never queries tmux.
- `ResolveSession` (method) — ResolveSession snapshots live tmux state and returns this exact winlink's parent session. It returns [SnapshotLookupError] cardinality errors.
- `ResolveActivePane` (method) — ResolveActivePane snapshots live tmux state and returns the first active pane in this exact winlink view. A missing active pane returns ok false.
- `Cmd` (method) — Cmd executes a tmux subcommand targeted to the window's stable ID.
- `SearchPanes` (method) — SearchPanes returns this window's pane views selected by tmux's live -f expression. A nil filter omits -f and a nonnil empty filter sends an explicit expression. Stable session and window identities limit the projection.
- `SelectLayout` (method) — SelectLayout applies one layout operation to the receiver's exact winlink. It changes pane geometry without selecting the window or promising client focus. The materialized receiver is not refreshed, so callers that need current pane geometry must obtain a new snapshot or refresh related models. A transport or context error can be delivery-ambiguous; the void result cannot carry partial state and no rollback is attempted.
- `NextLayout` (method) — NextLayout applies the next preset layout to the receiver's exact winlink. It changes pane geometry without selecting or refreshing the window. A transport or context error can be delivery-ambiguous; the void result cannot carry partial state and no rollback is attempted.
- `PreviousLayout` (method) — PreviousLayout applies the previous preset layout to the receiver's exact winlink. It changes pane geometry without selecting or refreshing the window. A transport or context error can be delivery-ambiguous; the void result cannot carry partial state and no rollback is attempted.
- `NewWindow` (method) — NewWindow creates a window relative to the receiver's exact winlink. Set Direction to [NewWindowDirectionAfter] or [NewWindowDirectionBefore] for non-destructive relative creation. With the zero Direction, tmux targets the receiver's occupied index and normally returns a command error; KillExisting can destroy and replace that target. Attach changes the current window only in that target session. Index is rejected before execution because the receiver already supplies the target position. SelectExisting has no no-output recovery on this exact-target form; tmux must print the created WindowID.
- `Rename` (method) — Rename changes the stable window through the receiver's exact winlink and returns a canonical freshly materialized [Window]. The returned winlink may therefore use another session when the WindowID is linked. If the command succeeds but refresh fails, Rename returns the receiver with that error. A transport or context error can be delivery-ambiguous; no rollback is attempted.
- `Select` (method) — Select makes the receiver's exact winlink current in its session. It does not promise focus for clients attached to other sessions. Select returns a canonical freshly materialized [Window], which may use another linked session for the same WindowID. If the command succeeds but refresh fails, it returns the receiver with that error. A transport or context error can be delivery-ambiguous; no rollback is attempted.
- `Link` (method) — Link adds the stable window to TargetSession as another winlink, targeting the source through the receiver's exact session. Unless Detach is set, tmux makes the new link current in the target session; this is not a global client-focus guarantee. Link does not refresh or mutate the materialized source [Window]. A transport or context error can be delivery-ambiguous; the void result cannot carry the new winlink identity and no rollback is attempted.
- `Unlink` (method) — Unlink removes the receiver's exact session winlink without refreshing the materialized receiver. Without KillIfLast, tmux rejects removal of a stable window's only link; with it, that window is destroyed. A transport or context error can be delivery-ambiguous; the void result cannot carry partial identity and no rollback is attempted.
- `Move` (method) — Move removes the receiver's exact winlink and places it in TargetSession, or renumbers the selected session when Renumber is set. Unless NoSelect is set, tmux makes the moved winlink current in the destination session; this is not a global client-focus guarantee. The stable WindowID does not by itself identify either linked view.
- `Swap` (method) — Swap exchanges the receiver and Target exact winlinks. Their stable WindowIDs move to the opposite session-and-index views; a WindowID alone does not identify either endpoint. Unless Detach is set, tmux may change the affected sessions' current-window selection; this is not a global client-focus guarantee.
- `SelectPane` (method) — SelectPane makes an exact or relative pane active in the receiver's exact winlink without selecting the window in its session. Target must belong to that same SessionID and WindowID; a PaneID alone does not identify a linked view. The returned [Pane] is the freshly materialized active pane in the receiver context, not a canonical ID-only view.
- `LastPane` (method) — LastPane targets the receiver's exact winlink. Its zero request makes the previously active pane active without selecting the window in its session. With an Input mode, tmux changes the previous pane's input state without selecting it; the returned [Pane] is still the freshly materialized active pane in the receiver context.
- `Rotate` (method) — Rotate rotates pane positions in the receiver's exact winlink without selecting the window or promising client focus. It returns a freshly materialized exact [Window] preserving the receiver SessionID, rather than a canonical ID-only view. If the command succeeds but refresh fails, Rotate returns the receiver with that error; earlier failures return zero.
- `Resize` (method) — Resize changes the stable window's size through the receiver's exact winlink. It does not select the window or promise any client focus. Resize returns a canonical freshly materialized [Window], which may use another linked session for the same WindowID. If the command succeeds but refresh fails, it returns the receiver with that error; other command failures return a zero Window. A transport or context error can be delivery-ambiguous and no rollback is attempted.
- `Respawn` (method) — Respawn restarts the stable window process through the receiver's exact winlink. It does not select the window or promise any client focus. Respawn returns a canonical freshly materialized [Window], which may use another linked session for the same WindowID. If the command succeeds but refresh fails, it returns the receiver with that error; earlier failures return zero. Completed stderr produces a redacted [CommandError]; nonzero exits without stderr are followed by refresh.
