/**
|
|
* A QXEmbed widget serves as an embedder that can manage one single embedded
|
|
* X-window. These so-called client windows can be arbitrary Qt or non Qt
|
|
* applications.
|
|
*
|
|
* There are two different ways of using QXEmbed,
|
|
* from the client side or from the embedder's side.
|
|
*
|
|
* Embedding from the client's side requires that the client knows the
|
|
* window identifier of the respective embedder widget. Use either
|
|
* embedClientIntoWindow() or the high-level wrapper processClientCmdline().
|
|
* This is only possible when the client is a Qt application.
|
|
*
|
|
* When using it from the embedder's side, you must know the window
|
|
* identifier of the window that should be embedded. Simply call embed()
|
|
* with this identifier as parameter. If the client is a Qt application,
|
|
* make sure it has called QXEmbed::initialize(). Otherwise you should
|
|
* probably call setProtocol(XPLAIN) before embed().
|
|
*
|
|
* Reimplement the change handler windowChanged() to catch embedding or
|
|
* the destruction of embedded windows. In the latter case, the
|
|
* embedder also emits a signal embeddedWindowDestroyed() for
|
|
* convenience.
|
|
*
|
|
* @short The QXEmbed widget is a graphical socket that can embed an external X-Window.
