開発環境の準備 下のページから 「JREあり」の「Java」のを落とせ。 解凍したら終わりだ。たぶんな。 http //mergedoc.sourceforge.jp/index.html#/pleiades_distros4.2.html 管理者権限が必要そうなら教授に言え。すぐに対応してくれる。 してくれないならその研究室はやめとけ。 おまじない public class Hoge { public static void main (String[] args) { // ここに何か書けば動く System.out.println("あいうえお"); } } ぬるぽ nullチェックしろクズ SWT, AWT, Swing が混在したGUIを作りたい 大先輩が残していった研究成果がSwingでつくってあった、でも自分はSWTを使いたい。（その逆でもおk） そんな人に便利。 Composite composite = new Composite(parent, SWT.EMBEDDED | SWT.NO_BACKGROUND); Frame frame = SWT_AWT.new_Frame(composite); できるにはできるけど、こんなことやってると糞コードが出来上がるから 0から全部書き直そうね。
