How to remove QLayout from other QLayout?

I have a layout that contain other layout (sublayout). I need to remove sublayout with content from layout. How i can do it?

QVBoxLayout* mainLayout = new QVBoxLayout; 
QHBoxLayout* subLayout = new QHBoxLayout; 
for(int i = 0; i < 3; i++)
   subLayout->addWidget(new QPushButton(this)); //some content of sublayout
mainLayout->addLayout(subLayout);
setLayout(mainLayout);

There are only QLayout::removeWidget(), but not something like QLayout::removeLayout() in this class. Just delete subLayout or 

QLayoutItem *item;
while ((item = subLayout->takeAt(0)))
   delete item;
delete subLayout;

have no correct effect too (Content still remains on the screen).

So how?

void QLayout::removeItem(QLayoutItem *item)

Removes the layout item item from the layout. It is the caller's responsibility to delete the item.

Notice that item can be a layout (since QLayout inherits QLayoutItem).
