+/**
+    A Linux-specific class that can embed a foreign X11 widget.
+
+    Use this class to embed a foreign X11 widget from other toolkits such as
+    GTK+ or QT.
+
+    There are two ways to initiate the Xembed protocol. Either the client creates
+    a window and passes this to the host (client initiated) or the host
+    creates a window in which the client can reparent it's client widget
+    (host initiated). XEmbedComponent supports both protocol types.
+
+    This is how you embed a GTK+ widget: if you are using the client
+    initiated version of the protocol, then create a new gtk widget with
+    gtk_plug_new (0). Then query the window id of the plug via gtk_plug_get_id().
+    Pass this id to the constructor of this class.
+
+    If you are using the host initiated version of the protocol, then first create
+    the XEmbedComponent using the default constructor. Use getHostWindowID to get
+    the window id of the host, use this to construct your gtk plug via gtk_plug_new.
+
+    A similar approach can be used to embed QT widgets via QT's QX11EmbedWidget
+    class.
+
+    Other toolkits or raw X11 widgets should follow the X11 embed protocol:
+    https://specifications.freedesktop.org/xembed-spec/xembed-spec-latest.html
