visible main form?

[triperzonak]

hi.

i create a form main and form for login, at the start of the program i will call the login form then if ok enable main form or if cancel exit..

my problem is when i call the form login in class constructor at the start of the program, i only see the login form without the main form. what i want is to see both at the start of the program but login form as modal. how?

tnks

QTimer::singleShot(0, &mw, SLOT(displayLogin());
return app.exec();
}

public slots:
void displayLogin(){
LoginDialog dlg(this);
dlg.exec();
}
};
