在Mac OSX中复制文件所需的DataFlavor是什么 [英] What is the required DataFlavor to copy files in Mac OSX

问题描述

我正在研究可以将文件复制到系统剪贴板的Java代码。

I'm currently working on Java code that can copy files into the system clipboard.

对于Windows和Linux，我已经开始工作了。对于OSX，我尝试了几种口味，但Finder中的粘贴操作从未激活。

For Windows and Linux I already got it working. For OSX I tried several flavors but the "Paste" action in Finder never cames active.

任何想法Finder需要哪些DataFlavor设置？

Any idea which DataFlavor settings are required for Finder?

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" );

返回风味数据的方法：

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 );
}

推荐答案

也许你应该尝试 DataFlavor＃javaFileListFlavor 。

摘自API文档：

DataFlavor＃javaFileListFlavor （链接）

向/从Java（和底层平台）传输文件列表DataFlavor使用此类型/子类型和java.util.List的表示类。列表的每个元素都必须/保证是java.io.File类型。

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.
