'Swing Progress'에 해당되는 글 1건

예를들어 스윙 어플리케이션에서 Progress를 뛰어주고 싶을경우에 사용하면 되겠습니다. 

Progress를 JDialog에서 생성하여 뛰워줘도 됩니다. 하지만 Progress 라는 것은 어떠한 작업을 할 경우

1. DataBase

2. File Load

... 등등이 되겠지요 가져오는 값들이 대용량일 경우에는 시간이 걸리기 때문에 이러한 상황에 대부분 Progress를 사용합니다. 

이러한 경우 타이틀바가 필요가 없게되고 작업이 다 끝났을 경우 Progress 는 사라지기 때문에 JDialog보다는 JWindow를 사용하여 구현하는게 좋겟지요 UI상에서도 보기 좋습니다.
