A simple choice dialog won't work...
I wanted to pop up two buttons for the user to choose between two
options ("primary" and "secondary"), returning true or false depending
which was chosen. I tried this
gboolean
choose_option (gchar *title, gchar * primary, gchar * secondary)
{
GtkWidget *dialog;
dialog = gtk_dialog_new_with_buttons (title,
GTK_WINDOW (Denemo.window),
(GtkDialogFlags) (GTK_DIALOG_MODAL |
GTK_DIALOG_DESTROY_WITH_PARENT),
primary, GTK_RESPONSE_ACCEPT,
secondary,GTK_RESPONSE_REJECT,
NULL);
g_signal_connect_swapped (dialog, "response", G_CALLBACK
(gtk_widget_destroy), dialog);
return (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT);
}
but it seems to return 0 for both button presses. What am I doing wrong?
I'm using GTK3 on a Debian stable installation.

GTK_RESPONSE_REJECT Generic response id, not used by GTK+ dialogs
GTK_RESPONSE_ACCEPT Generic response id, not used by GTK+ dialogs
Maybe try
GTK_RESPONSE_OK and GTK_RESPONSE_CANCEL
If that does not help, I may test your code next weekend --guess I have
to add a few lines to get a working example.

Hmm, I wonder what that means - "Generic response id" ... I understood
that the idea of the pairs in the trailing arguments of
gtk_dialog_new_with_buttons () was that the button with the given text
would return the paired response id. I tried the ones you suggested, and
also two positive values with the same result.
After experimenting with a different bit of code, I think I've found the
cause of the problem: doing the widget destroy by responding to the
"response" signal seems to be ruining the return value.
So, I seem to be back on track - the code that works is below.
Thank you for your prompt response!

That is interesting. Indeed I had a feeling in that direction -- but not an exact idea what may went wrong. Unfortunately testing that takes a few minutes of time, and I am not really experienced with plain C code, I generally use Ruby or Nim. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
