Great. One usage tip (the documentation is not yet finished): Use qxembed from
the client side and not from the server side. That means: not the embedding
widget does the reparenting but vice versa: the client-module embeds itself.

This is trivial with qxembed. Here's a tiny example of a standalone qxembed
widget that will embed a qmultilineedit as client.

First the server:

#include <qapplication.h>
#include <qtextstream.h>
#include <qxembed.h>

int main( int argc, char **argv )
{
    QApplication a( argc, argv );
    QXEmbed qx;
    a.setMainWidget( &qx );
    qx.show();
    QApplication::flushX();
    if ( !fork() )
	execlp("client_program",  "client_program",
	       "-embed",  QString::number(qx.winId()).latin1(),
	       0);
    return a.exec();
}


If you wonder about the flushX(), that's to avoid Xlib getting out of sync with
two processes. Unlikely but might happen.

And here's the applet, a simple qmultlineedit:

#include <qapplication.h>
#include <qmultilineedit.h>
#include "qxembed.h"

int main( int argc, char **argv )
{
    QApplication a( argc, argv );
    QMultiLineEdit me;
    a.setMainWidget( &me );
    if ( !QXEmbed::processClientCmdline( &me, argc, argv ) )
	me.show();
    return a.exec();
}


Cute, isn't it? :-) 

Note that you *need* tomorrows Qt-2.0 snapshot to get this working properly.
The public Qt CVS will be updated in a few hours, to be precise.
