3. Program ćwiczenia

Zad3

Aplikacja w której po wciśnięciu przycisku Formularz uruchamia się okno do wprowadzania danych takich jak: Wiek, Imię, Nazwisko i Płeć. Po zaakceptowaniu wprowadzonych danych, dane te wyświetlają się w oknie głównym.

Poniżej ilustracja odzwierciedlająca pożądaną aplikację.

Zad4

Aplikacja notatnik, powinna posiadać Menu z podstawowymi poleceniami edytora tekstu które spełniają swoje funkcje, oraz Menu kontekstowe.
