我正在为python + tkinter中的xfreerdp编写一个轻量级客户端。在屏幕的顶部，我放置了一个带有按钮的菜单，这些按钮应该出现在所有程序的顶部。只要我不使用xfreerdp的 /f 开关，它就可以工作。据我了解，如果另一个程序以全屏模式启动， wm_attributes ("-topmost", True)将不起作用。
tkinter中是否有另一种方法可以在全屏应用程序之上显示 Toplevel？
或者在tkinter窗口中运行xfreerdp的方法？
或者为 Python使用不同的 GUI 的类似方法？

RootYTop = round((ScrHgth/2) - (RootWindowHeight/2))
