Hi to all,
I would pause the main thread for 2-3 sec and then exit from the application but I can not find a solution.

In my case when application starts a status dialog appears showing some result and then the main window is shown. There is a case where I would wait a couple of seconds ( to give to the user the time to read ) and then exit completely from the application. This is the code I wrote:

Qt Code: 
  1. void CertiIrisApp::init() //CertiIrisApp is the main application derived class
  2. {
  3.     start = new StartDlg(0); // start is a dialog showing some initialization results
  4.     start->show();
  5.     start->print(QString("> Welcome to CertiIris")); //print prints a message
  6.     processEvents();
  7.     start->print(QString("> Checking for Iris scanner..."));
  8.     if (checkIrisScanner())
  9.     {
  10.         start->print(QString("> Correct Iris scanner connected."));
  11.         processEvents();
  12.     }
  13.     else
  14.     {
  15.         QString msg = "> An incorrect iris scanner has been connected, contact author.";
  16.         start->print(msg);
  17.         processEvents();
  18.         Sleep(1); // I would wait to give the time to read
  19.         QCoreApplication::exit(1); //and then exit
  20.     }
  21.  
  22.     if ( connectToDB() == true )
  23.     {
  24.         QString str = "> " + QCoreApplication::applicationName() + " is successfully connected to the IrisServer.";
  25.         start->print(str);
  26.         processEvents();
  27.         onLoadDBRecords();
  28.     }
  29.     else
  30.     {
  31.         QString str = "> " + QCoreApplication::applicationName() + " could not connected to the IrisServer.";
  32.         start->print(str);
  33.         processEvents();
  34.     }
  35.  
  36.     start->hide(); // hide the dialog
  37.     delete start; // and delete it
  38.     m_mainWnd->show(); // here I show the main window
  39.     return;
  40. }

The problem of my code is that the program flow doesn't wait at the Sleep call and follow showing the next message.
Where is my mistake?
