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.

Qt Code: 
  1. #include <QtGui/QApplication>
  2.     #include "mainwindow.h"
  3.  
  4.     int main(int argc, char *argv[])
  5.     {
  6.         QApplication a(argc, argv);
  7.         MainWindow w;
  8.  
  9.         w.show();
  10.  
  11.         return a.exec();
  12.     }
To copy to clipboard, switch view to plain text mode 


Qt Code: 
  1. #include "mainwindow.h"
  2.     #include <QProcess>
  3.  
  4.     MainWindow::MainWindow(QWidget *parent)
  5.         : QMainWindow(parent)
  6.     {
  7.         QProcess * proc = new QProcess(this);
  8.         //proc->start("Artha");// -into"+QString((int)this->winId()));
  9.         proc->start("Artha -into"+QString((int)parent->winId()));
  10.  
  11.     }
  12.  
  13.  
  14.     MainWindow::~MainWindow()
  15.     {
  16.  
  17.     }

Qt Code: 
  1. #ifndef MAINWINDOW_H
  2.     #define MAINWINDOW_H
  3.  
  4.     #include <QtGui/QMainWindow>
  5.  
  6.     class MainWindow : public QMainWindow
  7.     {
  8.         Q_OBJECT
  9.  
  10.     public:
  11.         MainWindow(QWidget *parent = 0);
  12.         ~MainWindow();
  13.     };
  14.  
  15.     #endif // MAINWINDOW_H
