[rocket049]

I add a function in webview.go,it seems work correct.

// WidgetToWebView convert a Widget(it must be converted from WebView) back to WebView
func WidgetToWebView(widget *gtk.Widget) *WebView {
    obj := widget.Object
    p := unsafe.Pointer(widget.Native())
    return &WebView{&gtk.Widget{glib.InitiallyUnowned{obj}}, C.to_WebKitWebView((*C.GtkWidget)(p))}
}
