java - 在 Mac OSX 中复制文件所需的 DataFlavor 是什么

Question

我目前正在研究可以将文件复制到系统剪贴板中的 Java 代码。

对于 Windows 和 Linux，我已经让它工作了。对于 OSX，我尝试了几种风格，但 Finder 中的“粘贴”操作从未激活。

知道 Finder 需要哪些 DataFlavor 设置吗？

使用的口味:

DataFlavor.javaFileListFlavor
URILIST_FLAVOR = new DataFlavor( "text/uri-list" );
XFILELIST_FLAVOR = new DataFlavor( "application/x-java-file-list" );
GNOMEFILELIST_FLAVOR = new DataFlavor( "x-special/gnome-copied-files" );

返回 flavor 数据的方法:

public Object getTransferData( DataFlavor flavor ) throws UnsupportedFlavorException, IOException {
    if( FILELIST_FLAVOR.equals( flavor ) ) {
        if( List.class == flavor.getRepresentationClass() ) {
            return Arrays.asList( files );
        } else if( InputStream.class == flavor.getRepresentationClass() ) {
            return getStreamData( files, null );
        }
    } else if( DataFlavor.javaFileListFlavor.equals( flavor ) ) {
        if( List.class == flavor.getRepresentationClass() ) {
            return locallist;
        } else if( InputStream.class == flavor.getRepresentationClass() ) {
            return getStreamData( files, null );
        }
    } else if( URILIST_FLAVOR.equals( flavor ) ) {
        if( List.class == flavor.getRepresentationClass() ) {
            return Arrays.asList( files );
        } else if( InputStream.class == flavor.getRepresentationClass() ) {
            return getStreamData( files, null );
        }
    } else if( GNOMEFILELIST_FLAVOR.equals( flavor ) ) {
        if( List.class == flavor.getRepresentationClass() ) {
            return Arrays.asList( files );
        } else if( InputStream.class == flavor.getRepresentationClass() ) {
            // FIXME support cut and copy
            return getStreamData( files, "copy" );
        }
    } else if( XFILELIST_FLAVOR.equals( flavor ) ) {
        if( List.class == flavor.getRepresentationClass() ) {
            return locallist;
        } else if( InputStream.class == flavor.getRepresentationClass() ) {
            return getStreamData( files, null );
        }
    }
    throw new UnsupportedFlavorException( flavor );
}

也许你应该试试 DataFlavor#javaFileListFlavor .

API 文档摘录:

DataFlavor#javaFileListFlavor ( Link )

To transfer a list of files to/from Java (and the underlying platform) a DataFlavor of this type/subtype and representation class of java.util.List is used. Each element of the list is required/guaranteed to be of type java.io.File.
