我用 .Net 大约 2 分钟制作了这个非常简单的应用程序，但我需要用 Gtk# 移植它才能在 Linux 上正常工作。

我搜索了如何使背景透明但我没有运气；我还搜索了如何更改背景颜色，希望能找到等效的 TransparenceKey，但又没有运气了。

最重要的是：如何做到背景透明？

这是我的应用程序的代码；它是使用 Visual Studio 2010 和 .Net Framework 4 Client Profile 编写的

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Calendario {
    public partial class Calendar : Form {
        private Timer temporizador;
        private Label lblHora, lblDia, lblFecha;
        public Calendar () {
            InitializeComponent ();

            this.BackColor = System.Drawing.Color.Lime;
            this.ClientSize = new System.Drawing.Size ( 1600, 900 );
            this.DoubleBuffered = true;
            this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            this.ShowIcon = false;
            this.ShowInTaskbar = false;
            this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
            this.TransparencyKey = System.Drawing.Color.Lime;

            temporizador = new Timer();
            temporizador.Tick += new System.EventHandler ( this.temporizador_Tick );
            temporizador.Interval = 1;
            temporizador.Enabled = true;

            lblHora = new Label();
            lblHora.AutoSize = true;
            lblHora.Font = new System.Drawing.Font ( "GE Inspira", 64F, System.Drawing.FontStyle.Regular,
                                                    System.Drawing.GraphicsUnit.Point, ( ( byte ) ( 0 ) ) );
            lblHora.Location = new Point(1240, 12);
            lblHora.TextAlign = ContentAlignment.MiddleRight;
            lblHora.ForeColor = Color.FromArgb(255, 255, 32, 32);
            this.Controls.Add(lblHora);

            lblDia = new Label();
            lblDia.AutoSize = true;
            lblDia.Font = new System.Drawing.Font ( "GE Inspira", 36F, System.Drawing.FontStyle.Regular,
                                                    System.Drawing.GraphicsUnit.Point, ( ( byte ) ( 0 ) ) );
            lblDia.Location = new Point(1430, 117);
            lblDia.TextAlign = ContentAlignment.MiddleRight;
            lblDia.ForeColor = Color.FromArgb(255, 255, 8, 8);
            this.Controls.Add(lblDia);

            lblFecha = new Label();
            lblFecha.AutoSize = true;
            lblFecha.Font = new System.Drawing.Font ( "GE Inspira", 28F, System.Drawing.FontStyle.Regular,
                                                    System.Drawing.GraphicsUnit.Point, ( ( byte ) ( 0 ) ) );
            lblFecha.Location = new Point(1375, 186);
            lblFecha.TextAlign = ContentAlignment.MiddleRight;
            lblFecha.ForeColor = Color.FromArgb(255, 255, 0, 0);
            this.Controls.Add(lblFecha);
        }

        private void temporizador_Tick ( object sender, EventArgs e ) {
            lblHora.Text = DateTime.Now.ToString("HH:mm:ss");
            lblDia.Text = DiaDeLaSemana(DateTime.Now.DayOfWeek.ToString());
            lblFecha.Text = DateTime.Now.Date.ToShortDateString();
        }

        private string DiaDeLaSemana(string DayOfWeek) {
            switch (DayOfWeek) {
                case "Monday":
                    return "lunes";
                case "Tuesday":
                    return "martes";
                case "Wednesday":
                    return "miércoles";
                case "Thursday":
                    return "jueves";
                case "Friday":
                    return "viernes";
                case "Saturday":
                    return "sábado";
                default:
                    return "domingo";
            }
        }
    }
}

在此先感谢您的帮助！

我搜索了有关 GTK 的更多信息，它没有任何 100% 等效于 .Net 的 TransparenceKey，我用半透明背景进行了一些测试。但这不是我想要的方式。WinForms 和 GTK 以非常不同的方式工作（我知道这很明显），所以我将结束这个问题。

如果浪费了您的时间，我很抱歉...

Compiz 默认情况下没有打开窗口透明度。http://www.jameswigley.com/2012/04/27/making-ubuntu-unity-look-beautiful-by-enabling-transparency/

要在桌面 Windows 上启用透明度，请执行以下步骤：

1) Install Compiz Config Settings Manager (if you haven’t already)
sudo apt-get install compizconfig-settings-manager compiz-plugins
2) Alt + F2, type ‘ccsm’ and press Enter to launch CCSM.
3) Click on the ‘Opacity Brightness & Saturation’ Plugin / ‘Opacity’ tab.
4) Click ‘New’. Click ‘+’ and a new window will appear. Click ‘Grab’ and then select the desktop window on which you want to enable transparency. The name will then be filled into the Value field. Click ‘add’. Range 0 (transparent) – 100 (opaque).
5) Transparency can the be changed via the Window Values slider .
Some common window classes are ‘Ccsm’,'Nautilus’,'Dialog’,'Normal’,'Empathy’,'Gedit’,'Gnome-Terminal’
