I want to make child Qwidget to work as Dockable widget that is floatable.

Make sure it's geometry is not managed by a layout and reimplement corresponding mouse and/or key event handlers (depending on how it is supposed to be movable).

Pseudo for mouse movement:

// member variable
QPoint offset;
 
mousePressEvent()
{
    // offset from top left corner
    offset = event->pos();
}
 
mouseMoveEvent()
{
    // move to mouse pos - calculated offset
    move(mapToParent(event->pos()) - offset);
}
 
mouseReleaseEvent()
{
    // invalidate offset
    offset = QPoint();
}

// member variable
QPoint offset;

mousePressEvent()
{
    // offset from top left corner
    offset = event->pos();
}
 
mouseMoveEvent()
{
    // move to mouse pos - calculated offset
    move(mapToParent(event->pos()) - offset);
}

mouseReleaseEvent()
{
    // invalidate offset
    offset = QPoint();
}

What do you mean? QDockWidget can be made floating.
