Monobjc :: Add NSStatusItem

I'm trying to add an NSStatusItem from within the Monobjc bridge for Mono. The function gets called, and doesn't throw an exception, but my icon doesn't appear :(.

Here 's my code:

#define DEBUG_APP
using System;
using Monobjc.Cocoa;
using Monobjc;
namespace YvanSoftware.TwitMenu
{
  [ObjectiveCClass]
 public class TwitMenuController : NSObject
    {

  [ObjectiveCField]
  NSStatusItem _statusItem;

  [ObjectiveCMessage("awakeFromNib")]
  public void AwakeFromNib() 
  {
   try {
    if (_statusItem == null) {
     NSMenu menu = new NSMenu("");
     _statusItem = NSStatusBar.SystemStatusBar.StatusItemWithLength(32f);
     _statusItem.Image = NSImage.ImageNamed("twitter.png");
     NSMenuItem menuItem = new NSMenuItem("Send tweet!",new IntPtr(),"");
     menuItem.Ac开发者_StackOverflow中文版tionEvent += new ActionEventHandler(showTweetWindow);
     menu.AddItem(menuItem);
     _statusItem.Menu = menu;
     DebugPrint("Status item added??");
    }
   } catch (Exception ex) {
    DebugPrint(ex.Message); 
   }
  }

  public TwitMenuController(IntPtr i)  : base(i) {}

  public TwitMenuController() {} 

  public void showTweetWindow(Id sender) {
   Console.WriteLine("Not implemented. (0x01)");
  }

  [ObjectiveCMessage("showAbout:")]
  public void showAbout() {
   Console.WriteLine("Not implemented (0x02)"); 
  }

  void DebugPrint(string s) {
#if DEBUG_APP
   Console.WriteLine("*** DEBUG: " + s + " ***");
#endif
  }
    }
}

Thanks in advance,

Yvan


You have to retain the _statusItem variable right after its creation:

_statusItem = NSStatusBar.SystemStatusBar.StatusItemWithLength(32f);
_statusItem.Retain();
