How to centralize the QTreeWidget header

Question

How to centralize the QTreeWidget header?

I have the following QTreeWidget:

And I want to centralize the header to look like this:

I already tried to set this stylesheet:

QHeaderView::section {
     text-align: center;
 }

But it didn't work.

I know that with QTableWidget we can do something like this:

myTableWidget->horizontalHeaderItem(0)->setTextAlignment(Qt::AlignCenter);

But QTreeWidget doesn't have horizontalHeaderItem().

I'm on Qt 5.3.

Answer 1

I found a solution:

ui->myTreeWidget->header()->setDefaultAlignment(Qt::AlignCenter);

Set the default alignment as centralized to the QHeaderView.
