메인 프레임 시작시 Wxpython show 대화 상자

Question

나는 python과 wxpython을 사용하여 새로운 버전입니다. 주 프레임 시작 후 로그인 양식 대화 상자를 표시하는 데 문제가 있습니다. this picture

사용자가 로그인하지 않으면 기본 프레임에 액세스 할 수 없습니다. 사용자가 close/tutup 버튼을 클릭하면 메인 프레임도 닫힙니다. 나에게 샘플 코드를주세요 :

Answer 2

I wrote 올해 초. 여기에 도움이 될만한 예가 있습니다. 대화 상자에 프레임이 표시되지 않지만 변경하는 것은 간단합니다. 대신 로그인 대화 상자가 표시되고 사용자가 성공적으로 로그인하지 않으면 프레임이 표시되지 않습니다.
