I removed stadart system title bar by

setWindowFlags(Qt::FramelessWindowHint);

and I want make something like that

Layouts do not let you "cross" spacers (or any other elements) like that. Think of them like any other widgets. It would make no sense to create two overlapping buttons for example.

If you want the area in the center to take the space then put a widget in there and give it an expanding size policy.
