When using gtk_dialog_run () a recursive mainloop gets started and (some) event processing for the parent windows widgets get blocked. Unless you want some custom behaviour it then usually is not necessary to connect to the respond-signal (which *is* probably needed if you want multiple dialogs simultaneously). You also can force the dialog to respond by calling gtk_dialog_response(). This is useful if you e.g. want to cancel a dialog because of external conditions.

I didn't really get what the actual problem here is, but some advice
that might help:
* Unless you really, really know that you need to use threads, you
probably don't... using threads to get basic UI working is almost
certainly a bad idea.
* gtk_dialog_run() makes the dialog modal, so you can't use several
dialogs at once. You'll have to connect to the "respose" signal and
and show the widget yourself.
HTH,

I don't understand when the problem happens. The sourcecode is not very
specific and it does not explain how two dialogs come into play, since
after executing this code there is just one dialog open.

Do you actually use threads?

I did not yet really understand the problem, I suspect there is a lot of
background information missing.

Gtk Dialog box causing application to crash
Hi All,
I'm facing a strange problem while using GTK+ Dialog box
I've used two dialogs one in IF and other in ELSE
if (some condition)
{
GtkWidget *dialog1 = gtk_message_dialog_new (main_window,
GTK_DIALOG_DESTROY_WITH_PARENT,
GTK_MESSAGE_QUESTION,
GTK_BUTTONS_YES_NO,
"Send file to server %s?",
filename);
result = gtk_dialog_run (GTK_DIALOG (dialog1));
gtk_widget_destroy (dialog1);
}
else
{
GtkWidget *dialog2 = gtk_message_dialog_new (main_window,
GTK_DIALOG_DESTROY_WITH_PARENT,
GTK_MESSAGE_QUESTION,
GTK_BUTTONS_YES_NO,
"Download file %s?",
filename);
result = gtk_dialog_run (GTK_DIALOG (dialog2));
gtk_widget_destroy (dialog2);
}
However if I use just a single dialog box at a time, everything works
fine.
I've used gdk_threads_enter() and gdk_threads_leave() whereever possible.
these dialog boxes are created on 'select' event of CList so i cannot use
gdk_threads_enter() and gdk_threads_leave().
I need to have few more dialog boxes, but using only 2 is causing problems
of application crash.
Can anybody address this issue?
thanks and regards
Arvind
