[Mono-list] No VBox content in Dialog

[Frank Hrebabetzky]

Hi everybody,

The method below should pop up a Dialog for user input, convert it to a 
number and return that number. The problem is that the VBox part of the 
Dialog is always empty. Any hint?


   public static ushort AskItemNumber (string wintitle, string itemname,
     out bool valid)
   // Open a modal dialog and ask for the number of 'itemname' items.
   // Return this, or 0 if the user input is invalid.
   {
     Label	lab;
     Entry	entry;
     HBox	hbox;
     Dialog	dialog;
     ushort	n;

     lab	= new Label ("Number of " + itemname + "?");
     entry = new Entry (3);
     hbox = new HBox (false, 6);
     hbox.PackStart (lab);
     hbox.PackStart (entry);

     dialog = new Dialog (wintitle, null, DialogFlags.Modal);
     dialog.VBox.PackStart (lab);
     dialog.AddButton ("o.k.", ResponseType.Ok);
     dialog.Run();

     valid = true;  n=0;//s.c.
     try { n = Convert.ToUInt16(entry.Text);}
     catch { valid = false; }
     dialog.Destroy();
     if (valid) return n; else return 0;
   } // AskItemNumber
