gtkhtml-sharp 0.0.0.0 neutral Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. Lightweight HTML rendering widget. is a lightweight HTML rendering widget, as well as as simple graphical HTML editor. Developers can also use it as a widget container (). It is an easy way for viewing HTML documents in your application and for layout UI of your application throught HTML. does not have support for CSS or JavaScript. The following sample is a very minimal web browser. using System; using System.Net; using System.IO; using Gtk; namespace HtmlTest { class HtmlTest { HTML html; Entry entry; string currentUrl; static void Main (string[] args) { new HtmlTest(); } HtmlTest() { Application.Init (); Window win = new Window ("HtmlTest"); win.SetDefaultSize (800, 600); win.DeleteEvent += new DeleteEventHandler (OnWindowDelete); VBox vbox = new VBox (false, 1); win.Add (vbox); HBox hbox = new HBox (false, 1); Label label = new Label ("Address:"); entry = new Entry (""); entry.Activated += new EventHandler (OnEntryActivated); Button button = new Button ("Go!"); button.Clicked += new EventHandler (OnButtonClicked); hbox.PackStart (label, false, false, 1); hbox.PackStart (entry, true, true, 1); hbox.PackStart (button, false, false, 1); vbox.PackStart (hbox, false, false, 1); ScrolledWindow sw = new ScrolledWindow (); sw.VscrollbarPolicy = PolicyType.Always; sw.HscrollbarPolicy = PolicyType.Always; vbox.PackStart(sw, true, true, 1); html = new HTML (); html.LinkClicked += new LinkClickedHandler (OnLinkClicked); sw.Add (html); win.ShowAll(); Application.Run (); } void OnWindowDelete (object obj, DeleteEventArgs args) { Application.Quit(); } void OnButtonClicked (object obj, EventArgs args) { currentUrl = entry.Text.Trim(); LoadHtml (currentUrl); } void OnEntryActivated (object obj, EventArgs args) { OnButtonClicked (obj, args); } void OnLinkClicked (object obj, LinkClickedArgs args) { string newUrl; // decide absolute or relative if (args.Url.StartsWith("http://")) newUrl = args.Url; else newUrl = currentUrl + args.Url; try { LoadHtml (newUrl); } catch { } currentUrl = newUrl; } void LoadHtml (string URL) { HttpWebRequest web_request = (HttpWebRequest) WebRequest.Create (URL); HttpWebResponse web_response = (HttpWebResponse) web_request.GetResponse (); Stream stream = web_response.GetResponseStream (); byte [] buffer = new byte [8192]; HTMLStream html_stream = html.Begin (); int count; while ((count = stream.Read (buffer, 0, 8192)) != 0){ html_stream.Write (buffer, count); } html.End (html_stream, HTMLStreamStatus.Ok); } } } Gtk.Layout Atk.Implementor GLib.IWrapper GLib.IWrapper System.IDisposable Method System.Void Constructs an instance of a Gtk.HTML widget A derivative object.
