This provides webview functionality for embedded fltk windows.

Add fltk-webview to your fltk application's Cargo.toml file:

[dependencies]
fltk = "1"
fltk-webview = "0.4"

Then you can embed a webview using fltk_webview::Webview::create:

use fltk::{app, prelude::*, window};
use fltk_webview::*;
fn main() {
 let app = app::App::default();
 let mut win = window::Window::default()
 .with_size(800, 600)
 .with_label("Webview");
 let mut wv_win = window::Window::default()
 .with_size(790, 590)
 .center_of_parent();
 win.end();
 win.make_resizable(true);
 win.show();
 let mut wv = Webview::create(false, &mut wv_win);
 wv.navigate("https://google.com");
 
 app.run().unwrap();
}

• fltk-rs's dependencies, which can be found here.
• On Windows: No other dependencies.
• On macOS: No other dependencies.
• On Linux (X11 only): WebKitGTK and X11 dev packages.
  • Debian-based distros: sudo apt-get install libwebkit2gtk-4.1-dev libx11-dev.
  • RHEL-based distros: sudo dnf install webkit2gtk3-devel libX11-devel.

• This crate supports X11 only on Linux. On GNOME or Wayland sessions, force X11: GDK_BACKEND=x11.
• GNOME/Mutter can interfere with embedded toplevels; the X11 path mitigates this by making the webview unmanaged.
• If you see blanking, try: WEBKIT_DISABLE_COMPOSITING_MODE=1.
