Struct BackButtonProps 

Source 
pub struct BackButtonProps<F>
where
    F: Fn() + Clone + 'static,
{
    pub visible: Signal<bool>,
    pub on_click: Option<F>,
}
Available on crate feature leptos only.
Expand description

Props for the BackButton component.

Leptos component for the native back button.

Mirrors the React SDK’s BackButton ergonomics. Drives WebApp.BackButton: shows/hides it based on the visible signal, registers the optional click callback, and cleans both up on unmount.

§Examples

use leptos::prelude::*;
use telegram_webapp_sdk::leptos::BackButton;

#[component]
fn App() -> impl IntoView {
    let visible = RwSignal::new(true);
    view! {
        <BackButton
            visible=visible
            on_click=move || { web_sys::console::log_1(&"back".into()); }
        />
    }
}

§Required Props

§Optional Props

  • on_click: [F]
    • Optional callback invoked when the back button is clicked.

Fields§

§visible: Signal<bool>

Reactive flag controlling whether the back button is shown.

§on_click: Option<F>

Optional callback invoked when the back button is clicked.

Implementations§

Source§

impl<F> BackButtonProps<F>
where F: Fn() + Clone + 'static,

Source

pub fn builder() -> BackButtonPropsBuilder<F, ((), ())>

Create a builder for building BackButtonProps. On the builder, call .visible(...), .on_click(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of BackButtonProps.
