Focused window D-Bus

This GNOME Shell extension allows you to get the currently focused window using a D-Bus call. This allows you to get the focused window on Wayland, where there is no other way to do this.

Installation

You can install this extension from Gnome Extensions

https://extensions.gnome.org/extension/5592/focused-window-d-bus

Usage

Getting the current focused window:

gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/shell/extensions/FocusedWindow --method org.gnome.shell.extensions.FocusedWindow.Get

Subscribing to window focus changes:

gdbus monitor --session --dest org.gnome.Shell --object-path /org/gnome/shell/extensions/FocusedWindow
