C＃與GTK透明背景＃

我用.Net做了這個非常簡單的應用程序大約2分鐘，但我需要使用Gtk＃移植它，以便在Linux上正常工作。C＃與GTK透明背景＃

我搜索瞭如何使背景透明，但我沒有運氣;我也搜索瞭如何改變背景顏色，希望找到TransparenceKey的等價物，但沒有再次運氣。

最重要的是這個：如何做到背景透明？

這是我的應用程序的代碼;它是使用Visual Studio 2010和.Net Framework 4客戶端配置文件編寫的

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"; 
      } 
     } 
    } 
}

在此先感謝您的幫助！

默認情況下，Compiz沒有窗口透明度。 http://www.jameswigley.com/2012/04/27/making-ubuntu-unity-look-beautiful-by-enabling-transparency/

要啓用桌面Windows的透明度，請按照下列步驟操作：

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’

如果我沒有解釋得很好，我很抱歉。我不想使用Compiz，我會知道是否可以使用GTK＃設置透明背景，而不使用Composite Manager（Compiz，Xcompmgr等），或者如果可以使用alpha設置背景顏色。如果沒有，我會尋找另一種可能性;但現在我知道這是否可能。 –

@CarlosMartínezMedina - 這是可能的http://stackoverflow.com/questions/3908565/how-to-make-gtk-window-background-transparent –

我搜索關於GTK更多的信息，它不具有TransparenceKey從.net的任何100％對等，我做了一些具有半透明背景的測試。但它不是我想要的方式。 WinForms和GTK以非常不同的方式工作（我知道這很明顯），所以我會關閉這個問題。

對不起，如果我浪費你的時間...
