Maybe something like this will help:
void
on_bt_validate_clicked (GtkButton *button,
GtkEntry *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 */
else
/* Do something else */
}
The function g_ascii_isdigit checks wheter a character is an ASCII digit (0-9).
