推荐答案
唯一受支持和可靠的机制是XEmbed，但它需要嵌入式应用程序进行协作.没有协作的应用程序，您将陷入可怕的黑客世界.
the only supported and reliable mechanism is XEmbed, but it requires the embedded app to cooperate. Without a cooperating app, you're in a world of scary hacks.
您需要做的最基本的事情是XReparentWindow()，但是问题是您在与窗口管理器作斗争，而窗口管理器也希望重新创建窗口.您还可能会混淆该应用程序，它将期望ICCCM和EWMH行为，并且期望父窗口是WM框架.
The basic thing you need to do is XReparentWindow() but the problem is that you're fighting the window manager which will also want to reparent the window. You're also potentially confusing the app, which will be expecting ICCCM and EWMH behavior, and expecting the parent window to be a WM frame.
gnome面板的真正老版本GNOME 1.x具有吞咽功能，您可以尝试从中窃取hacks.
Really old GNOME 1.x versions of gnome panel had a swallow feature you could try to steal hacks from maybe.
如果没有相当广泛的X知识，这将是痛苦的，甚至并不一定能使它100％可靠.
Without pretty extensive X knowledge this will be painful, and evenwith it's not necessarily possible to make 100% reliable.
