How to ENABLE close button in Qt

Why when I run code bellow, I don't have close button, like on this screenshot?

There is also no close button with other flags, like Qt::WindowMinimizeButtonHint or Qt::WindowMinMaxButtonsHint and other.

#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QWidget wgt;
    wgt.setWindowFlags(Qt::Window | Qt::WindowMaximizeButtonHint);
    wgt.show();
    return a.exec();
}

Close button is available with wgt.setWindowFlag(Qt::Window). Even without wgt.setWindowFlag() is still available. But as soon as I add second flag like Qt::WindowMaximizeButtonHint or any other, with button, that must become unavailable, close button become unclickable too.

Try this:

#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QWidget wgt;
    wgt.setWindowFlags(Qt::Window | Qt::WindowMaximizeButtonHint | Qt::WindowMinimizeButtonHint | Qt::WindowCloseButtonHint);
    wgt.show();
    return a.exec();
}

More info:

A window flag is either a type or a hint. A type is used to specify various window-system properties for the widget.
