Gtk＃剪贴板复制/剪切/粘贴文件

如何使用Gtk＃将文件复制，剪切和粘贴到剪贴板。 我看到的每个例子都只显示放入剪贴板的文本。 如果有人有一个例子，我会很感激。

如果您的应用程序在Gnome / Unity上运行，您可以使用“x-special / gnome-copied-files”目标类型在剪贴板上移动/复制文件。 复制文件后，您应该能够使用文件管理器粘贴它，反之亦然。 下面是一个窗口类的例子，它执行此操作：

using System; using System.IO; using Gtk; public partial class MainWindow : Gtk.Window { private static Gdk.Atom _atom = Gdk.Atom.Intern("CLIPBOARD", false); private Gtk.Clipboard _clipBoard = Gtk.Clipboard.Get(_atom); private Gtk.FileChooserButton _fileCopy = null; private Gtk.FileChooserButton _folder = null; private Gtk.RadioButton _radioCopy = null; private Gtk.RadioButton _radioMove = null; private System.Text.ASCIIEncoding _encoding = new System.Text.ASCIIEncoding(); private string _action = null; private string _source = null; private string _destination = null; public MainWindow () : base(Gtk.WindowType.Toplevel) { SetDefaultSize(200, -1); var table = new Gtk.Table(5, 5, true); var separator = new Gtk.HSeparator(); var label0 = new Gtk.Label("Select file to copy/move"); _fileCopy = new Gtk.FileChooserButton("Select A File", Gtk.FileChooserAction.Open); _radioCopy = new Gtk.RadioButton("Copy"); _radioMove = new Gtk.RadioButton(_radioCopy, "Move"); var copyButton = new Gtk.Button("Copy"); Add(table); table.Attach(label0, 0, 4, 0, 1); table.Attach(_fileCopy, 0, 1, 1, 2); table.Attach(_radioCopy, 1, 2, 1, 2); table.Attach(_radioMove, 2, 3, 1, 2); table.Attach(copyButton, 3, 4, 1, 2); table.Attach(separator, 0, 4, 2, 3); var label1 = new Gtk.Label("Select destination for file(s)"); _folder = new Gtk.FileChooserButton("Select A File", Gtk.FileChooserAction.SelectFolder); var pasteButton = new Gtk.Button("Paste"); table.Attach(label1, 0, 4, 3, 4); table.Attach(_folder, 0, 1, 4, 5); table.Attach(pasteButton, 3, 4, 4, 5); DeleteEvent += OnDeleteEvent; copyButton.Clicked += OnCopyButtonClick; pasteButton.Clicked += OnPasteButtonClick; ShowAll(); } private void ClearGet(Gtk.Clipboard clipboard, Gtk.SelectionData selection, uint info) { var temp = _action + "\n" + _source; selection.Set(selection.Target, 8, _encoding.GetBytes(temp)); } private void ClearFunc(Gtk.Clipboard clipboard) { //??? } private void ReceivedFunc(Gtk.Clipboard clipboard, Gtk.SelectionData selection) { var temp = _encoding.GetString(selection.Data); if (temp==null) return; var items = temp.Split(); for (int i=1; i 

希望这会有所帮助，问候
