Qt::X11BypassWindowManagerHint

Hello,
I have made a Virtual KeyBoard for linux and I was using Libraries X11.
I have no problems about functionality of Keys
but I have a problem using Qt::X11BypassWindowManagerHint,

Code:

---

MyVirtualKeyboard(QWidget *parent = 0, Qt::WindowFlags fl = Qt::Tool | Qt::WindowStaysOnTopHint| Qt::X11BypassWindowManagerHint);

---

It doesn't show the title bar and its button (close, minimize,..).

There is an alternative solution without Qt::X11BypassWindowManagerHint to solve this problem?
Or there is a way to show title bar using this flag "Qt::X11BypassWindowManagerHint" ?
Could anybody please give me indications about solution or possibly indicate me examples ?

Thanks in advance
