Struct WebView 

pub struct WebView { /* private fields */ }

A webview showing one page.

The page is built the first time the view is painted, in the window it is painted in, and stays in that window. It sits at the element’s bounds in every frame the element is painted and is parked in every frame it is not. A parked page stays loaded.

The page takes keys while the view’s focus handle is focused, and a press in the page focuses the handle. On macOS, key equivalents (cmd or ctrl held) reach gpui’s key dispatch before the page sees them. On Windows, a key with ctrl or alt held, or a function key, goes to gpui’s key dispatch in place of the page when the keymap binds it in the view’s key context.

gpui elements behind the page are not hovered, and gpui’s cursor over the page is the arrow. On macOS the page sets the cursor over itself.

In a frame where a ui::cover recorded after the view overlaps it, the page is parked. On macOS a still of the page, taken while it is still up, is painted in its place; until the still arrives the page stays over the cover. Elsewhere the place is left empty.

Linux needs gpui on X11 and paints nothing under Wayland. Paints nothing off macOS, Windows and Linux.

Implementations

impl WebView

pub fn new( url: impl Into<String>, window: &mut Window, cx: &mut Context<'_, Self>, ) -> Self

pub fn location(&self) -> Option<&str>

The URL the page last reported; None before its first report.

pub fn title(&self) -> &str

pub fn is_loading(&self) -> bool

pub fn with_user_agent(self, user_agent: impl Into<String>) -> Self

The user agent the page is built with, in place of the platform’s. Read at the first paint. On macOS the default is Safari’s, with the installed Safari’s version.

pub fn load(&mut self, url: impl Into<String>)

Before the first paint, replaces the URL the page is built with. After it, navigates the page.

pub fn back(&mut self)

pub fn forward(&mut self)

pub fn reload(&mut self)

pub fn eval<T: DeserializeOwned + 'static>( &self, script: &str, timeout: Duration, cx: &App, ) -> Task<Result<T, EvalError>>

Evaluates script, a JavaScript expression, in the page’s main frame and decodes its value from JSON. undefined decodes as null; a promise is not awaited.
