16 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Create multiple windows in tauri.conf.json

Windows can be created in the Tauri configuration file (tauri.conf.json) under the app.windows array. Each window object requires: label (unique identifier), title (display name), width (in pixels), and height (in pixels).

Create multiple windows programmatically in Rust

Windows can be created programmatically in the Rust setup handler using tauri::WebviewWindowBuilder::new(app, label, webview_url) which returns a window that must be built with .build()?. Multiple windows can be created by calling this builder multiple times with different labels and URLs.
