Question

您能帮我理解为什么以下代码无法正常运行吗？右键单击时看不到托盘图标。

消息显然不是贬值的根本原因我的错是什么？

在Gtk3中测试的代码是

using Gtk;

//valac --pkg=gtk+-3.0 tray.vala

public class Main {

    class AppStatusIcon : Window {
        private StatusIcon trayicon;
        private Gtk.Menu menuSystem;

    public AppStatusIcon() {
        /* Create tray icon */
        trayicon = new StatusIcon.from_stock(Stock.HOME);
        trayicon.set_tooltip_text ("Tray");
        trayicon.set_visible(true);

        trayicon.activate.connect(about_clicked);

        create_menuSystem();
        trayicon.popup_menu.connect(menuSystem_popup);
    }

    /* Create menu for right button */
    public void create_menuSystem() {
        menuSystem = new Gtk.Menu();
        var menuAbout = new ImageMenuItem.from_stock(Stock.ABOUT, null);
        menuAbout.activate.connect(about_clicked);
        menuSystem.append(menuAbout);
        var menuQuit = new ImageMenuItem.from_stock(Stock.QUIT, null);
        menuQuit.activate.connect(Gtk.main_quit);
        menuSystem.append(menuQuit);
        menuSystem.show_all();
    }

    /* Show popup menu on right button */
    private void menuSystem_popup(uint button, uint time) {
        menuSystem.popup(null, null, null, button, time);
    }

    private void about_clicked() {
        var about = new AboutDialog();
        about.set_version("0.0.0");
        about.set_program_name("Tray");
        about.set_comments("Tray utility");
        about.set_copyright("vala");
        about.run();
        about.hide();
    }
    }

    public static int main (string[] args) {
        Gtk.init(ref args);
        var App = new AppStatusIcon();
        App.hide();
        Gtk.main();
        return 0;
    }
}

最新消息：现在valac不接受 menuSystem = new Menu（）; 这是歧义的Gtk.Menu或GLib.Menu 我选择了 menuSystem = new Gtk.Menu（）;

多谢
