在Mac OSX中复制文件所需的DataFlavor是什么

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 );
}
