Mam aplikację (prościutką) w wx w Pythonie, gdzie po otwarciu obrazka o "normalnym rozmiarze" widzę wszystko ok:

<image>obraz215.png</image>

ale jak otworzę obrazek bardzo "wąski" a "długi" w rozmiarze, sypie mi się menu okna, bo go nie widać dobrze:

Jak to poprawić? Dopiero zaczynam wx, więc proszę o cierpliwość:) Mój kod:
