Put Compose for Desktop content inside the Windows taskbar. Not the tray — the taskbar itself.

dependencies {
    implementation("uk.kulikov:compose-windows-taskbar:0.1.0")
}

Native bindings ship with it — JNA's stubs arrive transitively, nothing to build or unpack.

fun main() = application {
    WindowsTaskBar {
        Text("Hello, taskbar")
    }
}

It behaves like Compose's own Window / Tray: declarative, recomposes live, and keeps application { } alive while composed. On non-Windows it composes nothing and reports TaskBarError.UnsupportedOs — multiplatform apps keep building.

Content is clipped to the taskbar, so anything bigger goes in a Flyout — a borderless window anchored just off the taskbar, which can take focus and dismisses itself on click-away.

Windows has no API for this. Deskbands (IDeskBand) were removed in Windows 11, so — like every current taskbar-widget project — this creates a borderless, transparent Compose window and makes it a WS_CHILD of Shell_TrayWnd via SetParent. It then reconciles against the live taskbar geometry a few times a second, so it survives explorer.exe restarts, taskbar moves, DPI changes and display changes.

Run TaskBarDiagnostics.report() to see exactly what the library sees.

Separate Gradle build that consumes the published artifact — ./gradlew publishToMavenLocal, then ./gradlew -p samples :hello-taskbar:run.
