Failing to use QFileSystemModel in Qt

I am a newbie in QT. I am working on a app where I need to display the FileSystem using a treeview.

Basically I have a widget in my .ui file on which I have put a Treeview. Then in my .cpp file I have written the following code:

Code:

---

model = new QFileSystemModel(this);
    model->setRootPath(QDir::homePath());
    ui->treeView->setModel(model);

---

In my .h file I have put the following:

Code:

---

QFileSystemModel *model;

---

When I run the app, it displays the file system inside the treeview but it also shows Name, Type, Size, DateModified above it. I want to get rid of these.

How can I achieve it?

If you mean you don't want the header visible then

Code:

---

ui->treeView->header()->hide()
