Witajcie piszę swoją pierwszą aplikację okienkową gdzie muszę przełączyć content strony użyłem do tego cardlayout ( jako konstruktora w JFrame). Wszystko fajnie chodzi ale jak by nie było ale to bym tutaj nie prosił was o pomoc. Mianowicie jak przełcze się na inny jPanel to nie ładuje mi jego elementów tylko dopiero jak kliknę w miejsce gdzie on powinien być. Może kotoś podpowie mi czemu tak się dzieje ??
