Main Window Hide and Show from another dialogue form

arkantos.tas

Hi, I'm a newbie and in my program I'm just simply trying to create a login form. When the user logs in there is a option to log out. When the user logs out I want to show the main window again. But i'm unable to do so. I can hide the main window but can't bring it back. Any ideas how I might solve the problem

Hi.
while you show mainwindow, create dialog and show this.

    MainWindow w;

    UserLoginDlg* mydlg = new UserLoginDlg();

    mydlg->setModal(true);

    if(mydlg->exec() == QDialog::Accepted){
        w.show();
    }else return -1;

QDialog::Accepted
Means that the user has to log in. username and password is Correct.

Now left with only two things to do in the dialogue.

if user correct then:

void UserLoginDlg::on_Log_In_clicked()
{
QDialog::accept();
}

if user incorrect:
void UserLoginDlg::on_Log_Out_clicked() or The user then cut form
{
QDialog::reject();
}
