launching application in customized widget

[PstdEr]

Hi,
I would like to know is there any way to launch the application in the main window it self, instead of opening a new window.
what are the challenges in doing so, i googled and found out some sample , but its not working.


#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;

w.show();

return a.exec();
}




#include "mainwindow.h"
#include <QProcess>

MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
QProcess * proc = new QProcess(this);
//proc->start("Artha");// -into"+QString((int)this->winId()));
proc->start("Artha -into"+QString((int)parent->winId()));

}


MainWindow::~MainWindow()
{

}




#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QtGui/QMainWindow>

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
MainWindow(QWidget *parent = 0);
~MainWindow();
};

#endif // MAINWINDOW_H

That can be done but not in a cross-platform way. I.e. this involves native API.
