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文本被放入剪贴板。如果有人有示例,我将不胜感激。

最佳答案

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,您应该可以使用文件管理器粘贴它,反之亦然。下面是执行此操作的窗口类的示例:

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<items.Length; i++)
{
var fileFrom = items[i].Substring("file://".Length);
var fileTo = System.IO.Path.Combine(_destination, System.IO.Path.GetFileName(fileFrom));
if (items[0]=="copy")
File.Copy(fileFrom, fileTo);
else if (items[1]=="cut")
File.Move(fileFrom, fileTo);
}
}

private void OnCopyButtonClick(object obj, EventArgs args)
{
Console.WriteLine(_fileCopy.Uri);

_source = _fileCopy.Uri;
_action = _radioMove.Active ? "cut" : "copy";

var target0 = new TargetEntry("x-special/gnome-copied-files", 0, 0);
var target1 = new TargetEntry("text/uri-list", 0, 0);

_clipBoard.SetWithData(new TargetEntry[] {target0, target1}, ClearGet, ClearFunc);
}

private void OnPasteButtonClick(object obj, EventArgs args)
{
_destination = _folder.Filename;
_clipBoard.RequestContents(Gdk.Atom.Intern("x-special/gnome-copied-files", false), ReceivedFunc);
}

protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{
Application.Quit ();
a.RetVal = true;
}
}

希望这对你有帮助,问候
