    Take a look at QMessageBox

    You want something like a splash screen before open the main window of your application?

    When main window close, event loop terminate, then you can open second main window.

    Do you need something like this?
    Qt Code:
    1. #include <QtGui>
    2. int main (int argc, char** argv) {
    3. QApplication ap(argc, argv);
    4.  
    5. QWidget *window1 = new QWidget(0);
    6. QWidget *window2 = new QWidget(0);
    7.  
    8. QPushButton *button = new QPushButton("Open second Window", window1);
    9.  
    10. window1->show();
    11.  
    12. QObject::connect(button, SIGNAL(clicked()), window2, SLOT(show()));
    13.  
    14. return ap.exec();
    15. }
    To copy to clipboard, switch view to plain text mode
