Mam aplikację PyQt z paskiem narzędzi, zestaw przycisków i dolną obok dodatkowych przycisków. Chciałbym dodać wiadomość tekstową pod dolnym ciągiem znaków, które użytkownik może ukryć lub pokazać. Chciałbym, aby TextEdit rozszerzał dolną część po wyświetleniu, ale, gdy użytkownik ukrywa ją, chciałbym, aby ta dolna część została usunięta, nie wpływa na wysokość, szerokość, rozmiar lub dowolnego innego przycisku. Wyobraź sobie, że jesteś po prostu wziąć nożyczki w sekcji TextEdit, gdy użytkownik ukrywa je, ale potem приклеиваете z powrotem, gdy użytkownik chce je odzyskać. Czy jest to możliwe do zrobienia w PyQt? Najbliższe co znalazłem, to realizacja poniżej, która zmienia rozmiar wszystkich przycisków.
