hi..thanks for the code...but i think something is missing and it does not
work...here is what i`ve used:
void
on_bt_validate_clicked (GtkButton *button,
gpointer user_data)
{
GtkWidget *entry;
gboolean hasdigit = FALSE;
const gchar * string = gtk_entry_get_text (entry);
gint length = strlen (string);
gint i = 0;
while ((i < length) && (!hasdigit))
{
hasdigit = g_ascii_isdigit (string [i]);
i++;
}
if (hasdigit)
{
/* Show dialog */
GtkWidget *dialog1;
dialog1 = create_dialog1 ();
gtk_widget_show (dialog1);
}
else
{
/* Do something else */
}
}
there is no error but nothing is displayed and the application is
closed...please help
thanks
