A QXEmbed widget serves as an embedder that can manage one single embedded X-window. These so-called client windows can be arbitrary QWidgets.
There are two different ways of using QXEmbed, from the embedder's or from the client's side. When using it from the embedder's side, you already know the window identifier of the window that should be embedded. Simply call embed() with this identifier as parameter.
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().
If a window has been embedded succesfully, embeddedWinId() returns its id.
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.
| QXEmbed ( QWidget *parent=0, const char *name=0, WFlags f = 0 )
| QXEmbed |
Constructs a xembed widget.
The parent, name and f arguments are passed to the QFrame constructor.
| ~QXEmbed ()
| ~QXEmbed |
Destructor. Cleans up the focus if necessary.
| void initialize ()
| initialize |

| void embed ( WId w )
| embed |
Embeds the window with the identifier w into this xembed widget.
This function is useful if the server knows about the client window that should be embedded. Often it is vice versa: the client knows about its target embedder. In that case, it is not necessary to call embed(). Instead, the client will call the static function embedClientIntoWindow().
Parameters:
| w | the identifier of the window to embed |
See also: embeddedWinId()
| WId embeddedWinId ()
| embeddedWinId |
[const]
Returns the window identifier of the embedded window, or 0 if no window is embedded yet.
Returns: the id of the embedded window (0 if no window is embedded)
| void embedClientIntoWindow ( QWidget* client, WId window )
| embedClientIntoWindow |
[static]
A function for clients that embed themselves. The widget client will be embedded in the window window. The application has to ensure that window is the handle of the window identifier of an QXEmbed widget.
| bool processClientCmdline ( QWidget* client, int& argc, char ** argv )
| processClientCmdline |
[static]
A utility function for clients that embed theirselves. The widget client will be embedded in the window that is passed as -embed command line argument.
The function returns TRUE on sucess or FALSE if no such command line parameter is specified.

| QSize sizeHint ()
| sizeHint |
[const]
Returns a size sufficient for the embedded window
| QSize minimumSizeHint ()
| minimumSizeHint |
[const]
Returns the minimum size specified by the embedded window.
| QSizePolicy sizePolicy ()
| sizePolicy |
[const]
Specifies that this widget can use additional space, and that it can survive on less than sizeHint().
Reimplemented from QWidget.
| bool eventFilter ( QObject *, QEvent * )
| eventFilter |
| void setAutoDelete ( bool )
| setAutoDelete |
| bool autoDelete ()
| autoDelete |
[const]
| bool customWhatsThis ()
| customWhatsThis |
[const]
Reimplemented from QWidget.
| void enterWhatsThisMode ()
| enterWhatsThisMode |
| void embeddedWindowDestroyed ()
| embeddedWindowDestroyed |
[signal]
This signal is emitted when the embedded window has been destroyed.

| x11Event |
[protected]
Reimplemented from QWidget.
| void windowChanged ( WId w )
| windowChanged |
[protected virtual]
A change handler that indicates that the embedded window has been changed. The window handle can also be retrieved with embeddedWinId().
Parameters:
| w | the handle of the window that changed |
| bool focusNextPrevChild ( bool next )
| focusNextPrevChild |
