  1. Hello, Win32 API(Rhino) World!

    Posted on 1月 14th, 2013 by cx20

    Win32 API(Rhino)

    Win32 API は、Windows の機能にアクセスする為の API（Application Programming Interface）である。
    以下は Rhino にて SWT の非公開 API を使用した Win32 API 呼出しの例となっている。

    ソースコード

    Hello.js
    raw download
    importPackage(org.eclipse.swt.internal.win32);
 
var lpText = new TCHAR(0, "Hello, Win32 API World!", true);
var lpCaption = new TCHAR(0, "Hello, World", true);
OS.MessageBox(0, lpText, lpCaption, OS.MB_OK );

    実行方法

    C:¥> jrunscript -cp org.eclipse.swt.win32.win32.x86_3.6.1.v3655c.jar;. Hello.js

    実行結果

    ---------------------------
Hello, World!
---------------------------
Hello, Win32 API World!
---------------------------
OK

    Win32 API(BeanShell)

    Win32 API は、Windows の機能にアクセスする為の API（Application Programming Interface）である。
    以下は BeanShell にて SWT の非公開 API を使用した Win32 API 呼出しの例となっている。

    ソースコード

    Hello.bsh
    raw download
    import org.eclipse.swt.internal.win32.OS;
import org.eclipse.swt.internal.win32.TCHAR;
 
TCHAR lpText = new TCHAR(0, "Hello, Win32 API World!", true);
TCHAR lpCaption = new TCHAR(0, "Hello, World", true);
OS.MessageBox(0, lpText, lpCaption, OS.MB_OK );

    実行方法

    C:¥> SET CLASSPATH=bsh-2.0b4.jar;org.eclipse.swt.win32.win32.x86_3.6.1.v3655c.jar;%CLASSPATH%
C:¥> java bsh.Interpreter Hello.bsh

    Java 3D

    Java 3D は Java による 3D グラフィックライブラリである。
    以下は Fantom による Java 3D の使用例となっている。
