Struct webview_app::webview::WebView

pub struct WebView { /* private fields */ }

WebView is a Window running as program including a web view

WebView has to be built with the help of the WebView::builder function

Implementations

impl WebView

pub fn builder(app: &Application) -> WebViewBuilder<'_>

Creates a WebViewBuilder to construct a WebView.

Call several WebViewBuilder functions and create the WebView with build()

Example

#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
Allows console to show up in debug build but not release build.

use webview_app::webview::WebView;
 
fn on_activate(app: &Application)->WebView {
    let webview = 
        WebView::builder()
            .appid("de.uriegel.hello")
            .title("Rust Web View 🦞")
            .url("https://crates.io/crates/webview_app")
            .build();
    webview
}

pub fn can_close(&self, val: impl Fn() -> bool + 'static)

Sets a callback which is invoked on closing the app

You can prevent closing the app when returning false

Example

let can_close = true;
...
webview.can_close(move ||can_close);

pub fn connect_request<F: Fn(&Request, String, String, String) -> bool + 'static>( &self, on_request: F, )

When the webview is created, this callback is being called. You can then install WebView requests.

The Callback function has the following parameters: a request object, the request id, the command id (the Webview method) and the JSON payload.

A true return value signals that the request is being processed by this callback.

pub fn get_handle(&self) -> WebViewHandle

Retrieving a WebViewHandle to evaluate script in the WebView

pub fn eval(handle: WebViewHandle, script: &str)

Evaluates script in the WebView

You need a WebViewHandle which you can retrieve via WebView::get_handle

You do not need a reference to the WebView handle!

pub fn execute_javascript(script: &str)

Execute script in webview

Trait Implementations

impl Clone for WebView

fn clone(&self) -> WebView

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
