2011년8월10일_네트워크프로젝트(7일차)-출력창내용보존법 찾기(결과는 실패)
채팅흐름도
카톡(?)과 비슷하게 클라이언트가 글을 적어 서버로 보내면 서버는 접속한 모든 클라이언트에게 방송하고,
수신받은 클라이언트들을 수신된 메시지를 해석하여 데이터와 커멘드로 분류하고 데이터일 경우 상기의 흐름도와 같이,
좌우 위치를 정하고 수신받은 데이터의 크기를 측정하여 말풍선의 크기를 정해 그리고 글자를 삽입한다.
좌측에 위치한 사람은 좌측에서 우측을 보고 말을 하고 우측에 위치한 사람은 좌측을 보고 말을 한다.
이를 구현하기 위해 중요한 것은 이전 기록을 유지하는 것이다.
그래서 스크롤이 되어도 이전 데이터가 보존되는 함수가 있나 찾아 보았다.
우선 스크롤활성은 scrollok()이고,
스크롤관련함수 세 가지를 man page에서 찾아 보고 실행해 봤으나 원하는 결과를 얻지 못 했었다.
//2011년8월9일 보고서 참조.
그 외에 상기와 같은 다른 함수들도 테스트해 보았으나 원하는 결과를 얻지 못 하였다.
그래서 window가 아닌 panel과 form도 해봤다.
