I'm Using Glade, and Monodevelop to create a little GUI program.  I have
an IconList Widget that I have successfully populated.  I am trying to
capture a right mouse click and display a Dropdown menu of options.
 
In the IconList I have added a signal for on_iconlist1_select_icon.  In
the C++ code I have seen an example where the Gdk.Event.Type  is a
ButtonType even and the button number is part of this structure.  So you
just need to check for button ==3.  The same code I have below here
gives a null pointer exception to any reference into the selectEvent
variable.  Is this implemented?  a Bug?
 
Is there a better different way to do this with Mono and C# 
 
 
public void on_iconlist1_select_icon  (object o,
IconSelectedArgs args)
   {
 
    System.Console.WriteLine("Clicked Icon Selected."+ args.Num );
    System.Console.WriteLine("Clicked Icon Selected. " + args.Event );
    
//    System.Console.WriteLine("Clicked Icon
Selected." + args.Event.Type.Button );
 
//   Gdk.Event selectEvent = (Gdk.Event) args.Event;
//   System.Console.WriteLine("Clicked Icon Selected."+
selectEvent.Type.Button );
//   System.Console.WriteLine(args.Event.ToString());
   
   
//  
System.Console.WriteLine(Gdk.EventType.ButtonPress.ToString());
   
//   if (selectEvent.Type.ToString() ==
Gdk.EventType.ButtonPress.ToString())
   {
//    System.Console.WriteLine("Event Button Pressed");
   }
 

 //   if (eb.Button == 3)
 //   {
//     System.Console.WriteLine("Right Mouse Clicked for an Icon");
//    }
   
   }
   
 
// This signal I also added but it doesn't get called when and Icon is
selected, just when white space is selected.
  public void  on_iconlist1_button_press_event (object o, EventArgs
args)
  {
     System.Console.WriteLine("Button Press in IconList");
  }
 
 
Thanks,
Ian
