# webview-app
A Rust Web View Application for Windows and Linux similar to Electron. It offers the possibility to make web requests from the web site to the rust app and to send events from rust to the web site. The web site can be hosted as integrated resource, of course alternatively via HTTP(s):// or file://.

Sample webview_app:

webview_app >= version 1.0.0 is completely redesigned and it doesn't include a warp server anymore.

## Features <a name="features"></a>

webview_app includes following features:
* Functional approach with a builder pattern
* (almost) the same setup for Windows and Linux version
* Uses WebView2 on Windows and WebKitGtk-6.0 on Linux
* Can serve the web site via resources (single file approach)
* Optional save and restore of window bounds
* Has an integrated event sink mechanismen, so you can retrieve javascript events from the Rust app
* Offers the possibility to serve requests from javascript to Rust
* You can expand the Gtk4 Window (on Linux) with a custom header bar
* You can alternatively disable the Windows titlebar and borders, and you can build a title bar in HTML with standard Windows logic for closing, maximizing, restoring resizing, snap to dock, ...

Functional approach with webview builder:

```rs
fn on_activate(app: &Application)->WebView {
    let webview = WebView::builder(app)
        .title("Website form custom resources 🦞")
        .save_bounds()
        .devtools(true)
        .webroot(include_dir!("webroots/custom_resources"))
        .query_string("?param1=123&param2=456")
        .default_contextmenu_disabled()
        .build();

     webview
}

fn main() {
    Application::new("de.uriegel.hello")
    .on_activate(on_activate)
    .run();
}
```
