mainwindow disappearing

[locus]

Quick question:

Can a main window widget be invoked from pressing a button on a dialog?

i would like to do this, but when i try, the mainwindow, appears and then disappears.




void to_begin::on_okButton_clicked(){
MainWindow w;
w.show();
}



to_begin is a class that inherits the dialog as well as QDialog, and the dialog form on which ok_Button is located.
