* @Short_description: Toplevel for embedding into other processes

||
* @Title: GtkPlug
|
||
* @include: gtk/gtkx.h
|
||
* @See_also: #GtkSocket
|
||
*
|
||
* Together with #GtkSocket, #GtkPlug provides the ability to embed
|
||
* widgets from one process into another process in a fashion that is
|
||
* transparent to the user. One process creates a #GtkSocket widget
|
||
* and passes the ID of that widget’s window to the other process,
|
||
* which then creates a #GtkPlug with that window ID. Any widgets
|
||
* contained in the #GtkPlug then will appear inside the first
|
||
* application’s window.
|
||
*
|
||
* The communication between a #GtkSocket and a #GtkPlug follows the
|
||
* [XEmbed Protocol](http://www.freedesktop.org/Standards/xembed-spec).
|
||
* This protocol has also been implemented in other toolkits, e.g. Qt,
|
||
* allowing the same level of integration when embedding a Qt widget
|
||
* in GTK+ or vice versa.
|
||
*
|
||
* The #GtkPlug and #GtkSocket widgets are only available when GTK+
|
||
* is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined.
|
||
* They can only be used on a #GdkX11Display. To use #GtkPlug and
|
||
* #GtkSocket, you need to include the `gtk/gtkx.h` header.
