[GTK] [WK2] Add favicon support to the MiniBrowser

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Alberto Garcia]

Since r129994 there's API to get the favicon of a web view, so it
would be nice to use it in the MiniBrowser.

I guess you should also unref the favicon pixbuf in finalize().

> Tools/MiniBrowser/gtk/BrowserWindow.c:375
> +    cairo_surface_t *surface;
> +
> +    surface = webkit_web_view_get_favicon(window->webView);

Use a single line here:

cairo_surface_t *surface = webkit_web_view_get_favicon(window->webView);

> Tools/MiniBrowser/gtk/BrowserWindow.c:445
> +    g_signal_connect(window->uriEntry, "notify::text", G_CALLBACK(uriEntryTextChanged), (gpointer)window);

Don't use the gpointer cast, it's not needed, I know there are several there already, but that's old code copied from GtkLauncher, I think.

Just a small nit. WebKit coding style prefers early returns for these cases. So better 

if (!window->favicon)
    return;

If you're talking about faviconChanged(), there we want to clear the
favicon if it's NULL, not just return.

Ok, here's the new patch with these three changes.

I also decided not to clear the icon when the URI entry is changed. So
for this to work correctly, WebKitWebView has to emit notify::favicon
also when a new page is loaded and it has no favicon.

The emission of that signal need anyway to be changed since it's not
being emitted in most cases at the moment, but it should not affect
the MiniBrowser code.

Thanks for taking care of this, Berto. The patch looks good to me in general, I've just have a couple of really minor comments

You should provide a brief description for each of these functions

> Tools/MiniBrowser/gtk/BrowserWindow.c:397
> +        window->favicon = NULL;

You could use g_clear_object() here

Make sure we depend on a recent enough glib to use g_clear_object

webkit_web_view_get_favicon() now returns transfer none, so you shouldn't destroy the surface.
