Monobjc :: Add NSStatusItem

Question

Hi,

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.ActionEvent += 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();
