Hi,  
I started to code my first gui with ruby and gtk with the help of glade.  
Now everything works fine but I have two problems:

1.) If I exit my program via the X in the window-border (I hope you  
understand what I mean. The X which is in every window in the  
right-upper border) the window closes but the program keeps running. So  
if I execute it in the console I have to push strg+c to make my process  
end. How can I make my program finish if I push the X on the window?

2.) How do I invoka an error-dialog box? I know how to create one with  
glade but how can I call it?

Any help is really welcome 🙂

That X in the right-upper corner triggers a delete-event.

In glade-2, in the signals tab of your main window, add an event for the  
signal delete\_event, then add in your ruby file a code similar to:

```
def on_YOURWINDOW_delete_event widget, event, data = nil
    Gtk.main_quit
end

```

where YOURWINDOW is the widget name (in this case the main window)

> 2.) How do I invoka an error-dialog box? I know how to create one with glade but how can I call it?

glade-2 allows to create Dialogs, in the same way as you create Windows.  
Try YOURDIALOG.run for showing it as explained in  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3ADialog#run](http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3ADialog#run)

For error/warn/info dialogs, the best way seems to create a  
Gtk::MessageDialog, as shown in  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AMessageDialog](http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AMessageDialog)

Ahh thanks I tried it with the destroy-signal but with the delete one it  
works now 🙂

I created now a dialog with one button with glade and set it to  
invisible. If I wanna raise it I just call it with dialog1.show which  
work correctly.

thanks for your help
