embedding an application (in this case a terminal) within a QT application

问题

I am writing a QT application and I need to embed a terminal (we say,xterm) within a QDialog, like some KDE application (see kdevelop/kate/...).

I've been trying with: - QX11EmbedContainer placed into the QLayout of my QDialog - QProcess for the program I want to excecute

I expect the QProcess running within the QX11EmbedContainer, but it does not work.

The problem is that I can't put the xterm into the QX11EmbedContainer, the only thing I obtain is an xterm window (unfortunately separated from my QDialog). Does anybody got the same problem?

Sorry, I've tried your solution before posting oh this site and it does not work. I've solved switching to kdelibs and using those imports and this code

#include <kparts/part.h>
#include <assert.h>
#include <kde_terminal_interface.h>
#include <kpluginfactory.h>
#include <klibloader.h>

---

KLibFactory* factory = KLibLoader::self()->factory( "libkonsolepart" );
KParts::Part* p = static_cast<KParts::Part*>(factory->create( this,"tralala",         
QStringList() << "dio") );

assert(p);
setCentralWidget( p->widget() );
TerminalInterface *t = qobject_cast<TerminalInterface*>(p);
t->showShellInDir( QDir::home().path() );

You need to pass the window ID of the container to the xterm.

If you look at the example in the Qt help for QX11EmbedContainer, it just passes the window id to the QProcess. Change this to

 QProcess process(&container);
 QString executable(app.arguments()[1]);
 QStringList arguments;
 arguments << "-into" << QString::number(container.winId());
 process.start(executable, arguments);

where "-into" has been added to the arguments. From the XTerm man page:

-into windowId

Given an X window identifier (a decimal integer), xterm will reparent its top-level shell widget to that window. This is used to embed xterm within other applications.
