如何没有/一个窗口标题并且任务栏有不同的标题？

using System;
using System.Windows.Forms;

namespace SetWindowTitleAndTaskbar
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Text = "自定义窗口标题";
            this.Icon = new Icon("icon.ico");
            this.Tag = "自定义任务栏标题";
        }
    }
}

import Cocoa

class ViewController: NSViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.window?.title = "自定义窗口标题"
        self.view.window?.representedURL = URL(string: "自定义任务栏标题")
    }
}

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {
    gtk_init(&argc, &argv);

    GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(window), "自定义窗口标题");
    gtk_window_set_wmclass(GTK_WINDOW(window), "自定义任务栏标题", "自定义任务栏标题");

    g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);

    gtk_widget_show_all(window);
    gtk_main();

    return 0;
}
