[Gtk-sharp-list] Opening a DYK dialog

[Aaron Oxford]

Hi all,

I'm still struggling with this code (attached and posted below). I've 
tried all kinds of work-arounds, but the basic problem still comes 
down to what is demonstrated by the code. I'm guessing that since I 
haven't heard from anyone so far it works on some people's systems, 
but the question still remains: Why? :-)

Thanks in advance for any help,

Aaron.


using System;
using Gtk;
using Gdk;

public class Test
{
     private Label label = null;
     private int counter = 0;
     private bool configurationFailed = false;
     private Gtk.Window wnd;

     // Want to display a dialog, but can't...
     public static void Main()
     {
         if (!GLib.Thread.Supported) GLib.Thread.Init();
         Gdk.Threads.Init();
         Application.Init();

         Test t = new Test();

         // ...after constructing main window.
         t.showMessage("ioLet Composer.");

         GLib.Timeout.Add(100, new GLib.TimeoutHandler(t.Tick));

         // ...after starting the timer.
         //t.showMessage("VioLet Composer.");

         Gdk.Threads.Enter();

         // ...after the magic call.
         //t.showMessage("oLet Composer.");

         Application.Run();
         Gdk.Threads.Leave();
     }

     public Test()
     {
         wnd = new Gtk.Window("Test");
         wnd.Destroyed += new EventHandler(wnd_Destroyed);

         // Ladida, Gtk# is cool...
         VBox vbox = new VBox();
         label = new Label(counter.ToString());
         vbox.PackStart(label, false, false, 0);
         wnd.Add(vbox);
         wnd.ShowAll();

         // ...and then for some reason:
         // (this line invokes the timer based popup).
         configurationFailed = true;
     }

     void wnd_Destroyed(object sender, EventArgs e)
     {
         Application.Quit();
     }

     {

             //showMessage("new settings for VioLet Composer.");
             configurationFailed = false;
         }
         label.Text = "" + counter;
         counter++;
         return true;
     }

     private void showMessage(string p)
     {
         Gtk.Dialog dlg = new Dialog("caption", wnd, DialogFlags.Modal);
         dlg.AddButton(Gtk.Stock.Ok, Gtk.ResponseType.Ok);
         dlg.DefaultResponse = Gtk.ResponseType.Ok;
         ScrolledWindow sw = new ScrolledWindow();
         Label l = new Label(p);
         l.Wrap = true;
         sw.AddWithViewport(l);
         dlg.VBox.PackStart(sw);
         dlg.SetDefaultSize(320, 160);

         dlg.ShowAll();
         dlg.Run();
         dlg.Destroy();
