go-webkit6

WebkitGTK 6.0 bindings for go. Written with purego. Compatible with jwijenbergh/puregotk

This library is not useful by itself, you need a GTK library.

Basic example with jwijenbergh/puregotk

package main

import (
	"fmt"
	"os"
	"path"
	"unsafe"

	"github.com/sunaipa5/go-webkit6/webkit"

	"github.com/jwijenbergh/puregotk/v4/gobject"
	"github.com/jwijenbergh/puregotk/v4/gobject/types"
	"github.com/jwijenbergh/puregotk/v4/gtk"
)

	adw.Init()

	app := adw.NewApplication("com.test.app", gio.GApplicationFlagsNoneValue)
	defer app.Unref()

	actcb := func(_ gio.Application) {

	app.ConnectActivate(&actcb)

	if code := app.Run(len(os.Args), os.Args); code > 0 {
		os.Exit(code)
	}
}

	window := adw.NewApplicationWindow(&app.Application)

	mainBox := gtk.NewBox(gtk.OrientationVerticalValue, 0)

	headerBar := adw.NewHeaderBar()
	headerBar.AddCssClass("flat")
	headerBar.AddCssClass("compact")
	headerBar.SetShowTitle(false)
	headerBar.SetShowEndTitleButtons(true)
	mainBox.Append(&headerBar.Widget)

	webViewWidget := init_webview()

	webViewWidget.SetVexpand(true)
	webViewWidget.SetHexpand(true)
	webViewWidget.Show()

	mainBox.Append(webViewWidget)

	window.SetContent(&mainBox.Widget)
	window.SetDefaultSize(800, 600)
	window.Present()

}
