WPF-Window仅适用于自己的应用程序？

The Splashscreen/Loading-Window in my WPF application is set to Topmost="True". Now this windows in on top of all other windows even when you switch to another application (because loading will take some time). I don't want this kind of behavior.

我的WPF应用程序中的Splashscreen / Loading-Window设置为Topmost =“True”。现在这个窗口在所有其他窗口的顶部，即使你切换到另一个应用程序（因为加载将需要一些时间）。我不想要这种行为。

If I set Topmost="False" the window in not topmost at all. But If you switch back to my application after working with with another application my customers sometimes don't realize the Loading-Windows is still working. The application appears to be unresponsive because the Loading-Window in the background is still the active window and it is modal.

如果我将Topmost =“False”设置为不在最顶层的窗口。但是如果您在使用其他应用程序后切换回我的应用程序，我的客户有时也不会意识到Loading-Windows仍在运行。应用程序似乎没有响应，因为后台的加载窗口仍然是活动窗口，它是模态的。

I want to have the Loading-Window topmost but only if my application is in foreground. If you switch to another program the window should disappear and reappear topmost when you switch back.

我希望装载窗口位于最顶层，但前提是我的应用程序位于前台。如果切换到另一个程序，窗口应该消失，并在切换回时最重新出现。

2 个解决方案

You can try to use the "Owner" property of the window, with that the splash screen will always overlap the other windows.

您可以尝试使用窗口的“所有者”属性，因为启动屏幕将始终与其他窗口重叠。

I think maybe a change in the loading pattern of your MainWindow might help. If you can put to time consuming part of loading the window on a background thread then you can take this path:

我想也许你的MainWindow加载模式的改变可能会有所帮助。如果你可以花时间在后台线程上加载窗口，那么你可以采用这条路径：

Show MainWindow empty or bare bones (empty fields/grid etc)
显示MainWindow空或裸骨（空字段/网格等）
Launch async load method to get data and populate main window
启动异步加载方法以获取数据并填充主窗口
Create splash screen, set owner to self and show
创建启动画面，将所有者设置为自我并显示
make sure to close splash screen when load is complete.
确保在加载完成后关闭闪屏。

that should keep the splash on top while load is being processed.

这应该在处理负载时保持顶部的飞溅。
