SWT 사용하기
swt-3.1-win32-win32-x86
swt-win32-3138.dll 를 JAVA_HOME/bin 디렉토리로 복사하고
(이클립스)프로젝트 설정에서 swt.jar 를 불러오도록 하면 된다.
이걸 몰라서 한참 헤맸었다;;
SWT를 사용해서 만든 윈도우와 몇가지 컨트롤들의 모습이다.
AWT와는 다르게 깔끔하다.
메모리 사용량은 어떨지 모르겠지만ㅋ
지금 javaw 프로세스의 메모리 사용량이 120MB를 넘어갔는데(-_-;;) 이클립스 때문이다. 미리 로드해놓은게 있어서 그런지 내가 만든 프로그램을 실행시켜도 메모리 사용량이 100KB 이상 늘어나거나 하지는 않는다.
아래는 소스코드.
