Well thanks, i used this in void MainWindow::on_pushButton_clicked()

@Dialog mDialog ;
this->setVisible(false);
mDialog.exec();
this->setVisible(true);@

Now how i can back to main window by press on the back Button ( void Dialog::on_pushButton_clicked() ) in the dialog window ??

Regards.

I am not sure that i understand you. Correct me if i'm wrong.
You want create wizzard like app? If yes look at "http://qt-project.org/doc/qt-4.8/qwizard.html":http://qt-project.org/doc/qt-4.8/qwizard.html
Or if you asking how close dialog window by pressing back button then:
@this->close()@
in push button slot.

Hi!
There are many ways to doing that. It depends of architecture of you project.

1. variant:
   Make login dialog window as your main window, and put into it some login pass check function:
   @if(checkLogin(login, pass)){
   Dialog mDialog ;
   this->setVisible(false);
   mDialog.exec();
   this->setVisible(true);
   }else{
   QMessageBox::information(this, tr("Caption"), tr("Error text"), QMessageBox::Ok);
   }@

2. variant:
   Make login dialog window as child of your main window. Put somewhere "login" menu or button:
   @
   Dialog mLoginDialog ;
   mLoginDialog.exec();
   if(checkLogin(mLoginDialog.getLogin(), mLoginDialog.getPassword())){
   //some ini actions
   }else{
   QMessageBox::information(this, tr("Caption"), tr("Error text"), QMessageBox::Ok);
   }
   @

3. variant:
   Make two separate windows and put login check in main() function:

@int main(int argc, char *argv[])
{
QApplication a(argc, argv);
LoginDialog ld;
if(ld.exec() == QDialog::Accepted){
MainWindow w;
w.show();
}

return a.exec();

}@

But i belive everybody doing this in their own way :)
