focus-out-event on entry box asserts.

[Michel Selten <michel success demon nl>]

Hi,

I'm playing around with GTK-2.0.0 and have the following problem:
I'm trying to check the result of the contents of an gtk_entry control
when focus is lost. I've implemented the following signal handler:

g_signal_connect (G_OBJECT (edit_box),
                  "focus-out-event",
                  G_CALLBACK (LeaveEditBox),
                  NULL);

And the callback, which for now shows a messagebox, that is called when
the signal is emitted:

void LeaveEditBox (GtkWidget *widget, gpointer data)
{
  GtkWidget * msg_box;
  msg_box = gtk_message_dialog_new (GTK_WINDOW (root_window),
                                    GTK_DIALOG_MODAL,
                                    GTK_MESSAGE_INFO,
                                    GTK_BUTTONS_OK,
                                    "Lost focus signal.");
 gtk_dialog_run (GTK_DIALOG (msg_box));
 gtk_widget_destroy (msg_box);
}

Now, when I switch from my entry field to another control, my messagebox
shows: perfect. But, when I press the OK button, my app asserts:

batch (pid:30678): Gtk-ERROR **: file gtkentry.c: line 4179 (blink_cb):
assertion failed: (GTK_WIDGET_HAS_FOCUS (entry))
aborting...
Aborted

A bt in gdb gives the following:

Ok, so then I tried to do the same trick except I connected my signal to
a button instead of the entry. Everything went perfect.

Have I done something wrong or should I head over to BugZilla?

Thank you in advance,
