Well, I don't know. In my case I have FileChooseButton to select a
file. From code I call its method (on an object) SetFilename. But the
event SelectionChanged is called twice -- first with null filename,
the second time with proper one.
And in handler of this event I load data from selected file and show
the message dialog. Since the event is triggered twice I have two
Even if FileChooseButton has a bug (very odd double event) calling
modal dialog should stop processing events in main dialog -- at least
I would like to achieve this.
Below is shortened code:
public partial class MainWindow : Gtk.Window
protected virtual void OnFilechooserbuttonSelectionChanged
(object sender, System.EventArgs e)
var md = new MessageDialog(this, DialogFlags.Modal,
MessageType.Error, ButtonsType.Close, "Some error");
public MainWindow () : base(Gtk.WindowType.Toplevel)
var chooser = new FileChooserButton("title",FileChooserAction.Open);
chooser.SelectionChanged += OnFilechooserbuttonSelectionChanged;
protected void OnDeleteEvent (object sender, DeleteEventArgs a)
a.RetVal = true;
