これは私がstackoverflowで見つけたものです。Windows 7 で Windows の壁紙を変更するための Java クラスを探しています。
public class changewallpaper {
public static void main(String[] args) {
//supply your own path instead of using this one
String path = "C:\\Users\\d1j5\\Pictures\\asgardrealmofthegods.jpg";
SPI.INSTANCE.SystemParametersInfo(
new UINT_PTR(SPI.SPI_SETDESKWALLPAPER),
new UINT_PTR(0),
path,
new UINT_PTR(SPI.SPIF_UPDATEINIFILE | SPI.SPIF_SENDWININICHANGE));
} public interface SPI extends StdCallLibrary {
//from MSDN article
long SPI_SETDESKWALLPAPER = 20;
long SPIF_UPDATEINIFILE = 0x01;
long SPIF_SENDWININICHANGE = 0x02;
SPI INSTANCE = (SPI) Native.loadLibrary("user32", SPI.class, new HashMap<Object, Object>() {
{
put(OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);
put(OPTION_FUNCTION_MAPPER, W32APIFunctionMapper.UNICODE);
} }); boolean SystemParametersInfo(
UINT_PTR uiAction,
UINT_PTR uiParam,
String pvParam,
UINT_PTR fWinIni
);
}
}
