Question

我有一个caliburn.micro WPF应用程序，我正在通过调用此函数从F＃启动它：

问题是我需要有一个对主窗口的引用，以便我可以跟踪它是否仍然打开等，但它始终为null（因此注释代码）。注意这在运行“普通”MVVM应用程序并以类似方式初始化时工作正常：

            public void LaunchGUI()
            {
                if (_guiWindow == null)
                {
                    var windowThread = new Thread(() =>
                    {
                        try
                        {
                            // Create our context, and install it:
                            SynchronizationContext.SetSynchronizationContext(new DispatcherSynchronizationContext(Dispatcher.CurrentDispatcher));

                            AppBootstrapper.Initialize();
                            var app = new App();
                            app.InitializeComponent();


                            //guiWindow = app.MainWindow;
                            //// When the window closes, shut down the dispatcher
                            //guiWindow.Closed += (s, e) =>
                            //    Dispatcher.CurrentDispatcher.BeginInvokeShutdown(DispatcherPriority.Background);
                            //guiWindow.Closed += (s, e) =>
                            //    guiWindow = null;
                            //guiWindow.WindowState = WindowState.Minimized;
                            //guiWindow.Show();
                            //guiWindow.WindowState = WindowState.Normal;
                            //guiWindow.Activate();
                            // Start the Dispatcher Processing
                            Dispatcher.Run();
                        }
                        catch (Exception e)
                        {
                            LogMessage("error in gui thread: " + e);
                            //guiWindow.Close();
                            //guiWindow = null;
                        }

                    });
                    windowThread.SetApartmentState(ApartmentState.STA);
                    windowThread.IsBackground = true;
                    windowThread.Start();
                }
                else
                {
                    _guiWindow.WindowState = WindowState.Minimized;
                    _guiWindow.Show();
                    _guiWindow.WindowState = WindowState.Normal;
                    _guiWindow.Activate();
                }
            }
        }

我的问题是如何访问创建的主窗口？

Answer 1

//你得到这样的应用程序主窗口：

var _guiWindow = Application.Current.MainWindow as MainWindow;

在后台线程上访问由Caliburn.Micro应用程序创建的GUI窗口？
