Avalonia.PrimarySelection

X11 PRIMARY-selection access for Avalonia apps — the "highlight to copy, middle-click to paste" buffer that Unix users expect.

Avalonia's IClipboard only exposes the CLIPBOARD selection (Ctrl+C / Ctrl+V). This fills in the other half via direct libX11 P/Invoke. No subprocess, no reflection. On Windows, macOS, or any host without X11 it is a safe no-op.

dotnet add package Avalonia.PrimarySelection

using Avalonia.PrimarySelection;

// On middle-click in your text control
var text = await PrimarySelection.GetTextAsync();
if (text is not null) InsertAtCaret(text);

// When the user finishes a mouse selection
PrimarySelection.SetText(selectedText);

API

Member Description
bool IsSupported True iff a libX11 connection is available.
Task<string?> GetTextAsync(int timeoutMs = 200, CancellationToken) Read the PRIMARY selection.
void SetText(string? text) Claim ownership and serve text to peers until ownership is taken away.
void Clear() Release ownership if we hold it.

How it works

  • Read — opens its own X11 display connection, issues XConvertSelection for UTF8_STRING, polls briefly for the SelectionNotify reply, reads the resulting property. Synchronous on a worker thread, typically <20 ms.
  • Write — starts a tiny daemon thread once, claims XA_PRIMARY via XSetSelectionOwner, services SelectionRequest events from peers forever (or until another client takes ownership / the process exits). Supports the standard targets: TARGETS, TIMESTAMP, UTF8_STRING, STRING.

XWayland

Works through XWayland. Mutter / KWin / wlroots compositors bridge X11 PRIMARY ↔ wp_primary_selection_unstable_v1, so Wayland-native apps can middle-click-paste your text and you can read theirs.
