webkit-sharp正在阻止弹出窗口，我如何捕获WebKitWebView创建事件？

Question

我试图捕捉这样的事件......

class ExposedWebView : WebKit.WebView { 
    public event EventHandler Create 
    { 
     add 
     { 
      Signal signal = Signal.Lookup (this, "create"); 
      signal.AddDelegate (value); 
     } 
     remove 
     { 
      Signal signal = Signal.Lookup (this, "create"); 
      signal.RemoveDelegate (value); 
     } 
    } 
} 

，但我得到一个错误，当我尝试创建一个处理程序...

的GLib，GObject的-WARNING **：gsignal.c： 2375：信号create' is invalid for instance 0x20e8020'类型`__gtksharp_1_ExposedWebView'

任何人都知道为什么这不起作用？是否有另一种方式让弹出对话框在WebView中工作？

我不得不争取创建的Web视图，而不是“创造” ......

ExposedWebView webView = new ExposedWebView(); 
webView.CreateWebView += HandleCreateWebView; 

    void HandleCreateWebView (object o, CreateWebViewArgs args) 
    { 
     Window info = new Window(""); 
     info.DefaultWidth = 1000; 
     info.DefaultHeight = 700; 
     VBox vbox2 = new VBox(); 
     WebView child = new WebView(); 
     child.NavigationRequested += HandleNavigationRequested1; 
     vbox2.PackStart(child); 
     info.Add (vbox2); 
     info.ShowAll(); 
     args.RetVal = child; 
    } 


class ExposedWebView : WebKit.WebView { 
    public event CreateWebViewHandler CreateWebView 
    { 
     add 
     { 
      Signal signal = Signal.Lookup (this, "create-web-view", typeof(CreateWebViewArgs)); 
      signal.AddDelegate (value); 
     } 
     remove 
     { 
      Signal signal = Signal.Lookup (this, "create-web-view", typeof(CreateWebViewArgs)); 
      signal.RemoveDelegate (value); 
     } 
    } 

    [DefaultSignalHandler (Type = typeof(WebView), ConnectionMethod = "OverrideCreateWebView")] 
    protected virtual WebView OnCreateWebView (WebFrame frame) 
    { 
     ExposedWebView webView = new ExposedWebView(); 
     Value empty = Value.Empty; 
     ValueArray valueArray = new ValueArray (2u); 
     Value[] array = new Value[2]; 
     array [0] = new Value (this); 
     valueArray.Append (array [0]); 
     array [1] = new Value (frame); 
     valueArray.Append (array [1]); 
     GLib.Object.g_signal_chain_from_overridden (valueArray.ArrayPtr, ref empty); 
     Value[] array2 = array; 
     for (int i = 0; i < array2.Length; i++) 
     { 
      Value value = array2 [i]; 
      value.Dispose(); 
     } 
     return webView; 
    } 
} 

public delegate void CreateWebViewHandler (object o, CreateWebViewArgs args); 

public class CreateWebViewArgs : SignalArgs 
{ 
    // 
    // Properties 
    // 

    public WebFrame Frame 
    { 
     get 
     { 
      return (WebFrame)base.Args [0]; 
     } 
    } 
}
