The example will have to be updated to current V standards before any further actions can be taken.

Does indeed have issues:

module main

import ui
import ui.webview

struct App {
	webview &webview.WebView
}

fn main() {
	mut app := &App{
		webview: voidptr(0)
	}
	window := ui.window(
		width: 800
		height: 100
		title: 'V ui.webview demo'
		children: [
			ui.row(
				// stretch: true
				margin: ui.Margin{10, 10, 10, 10}
				height: 100
				children: [
					ui.button(
						text: 'Open'
						width: 70
						height: 100
						on_click: fn (b &ui.Button) {
							// println("onclick open")
							webview.new_window(
								url: 'https://github.com/revosw/ui/tree/master'
								title: 'hello'
							)
						}
					),
					ui.button(
						text: 'Navigate to google'
						on_click: fn (b &ui.Button) {
							// println("onclick google")
							// app.webview.navigate("https://google.com")
						}
					),
					ui.button(
						text: 'Navigate to steam'
						on_click: fn (b &ui.Button) {
							// println("onclick steam")
							// app.webview.navigate("https://steampowered.com")
						}
					),
					ui.button(
						text: 'Rig on_navigate'
						on_click: fn (b &ui.Button) {
							// println("onclick rig")
							// app.webview.on_navigate(fn (url string) {
							// 	exit(0)
							// })
						}
					),
					ui.button(
						text: 'Run javascript'
						on_click: fn (b &ui.Button) {
							// println("onclick javascript")
							// app.webview.exec("alert('Ran some javascript')")
						}
					),
				]
			),
		]
	)
	ui.run(window)
}
