#![allow(non_upper_case_globals, non_snake_case)]
//! Example: Webview Renderer
//! -------------------------
//!
//! This example shows how to use the dioxus_desktop crate to build a basic desktop application.
//!
//! Under the hood, the dioxus_desktop crate bridges a native Dioxus VirtualDom with a custom prebuit application running
//! in the webview runtime. Custom handlers are provided for the webview instance to consume patches and emit user events
//! into the native VDom instance.
//!
//! Currently, NodeRefs won't work properly, but all other event functionality will.
