Question

Pretty simple task but I didn’t manage to find anything useful in documentation. I want a QTreeView to contain a single column called “Files” with data from QFileSystemView. Here’s what I’ve got:

    QFileSystemModel *projectFiles = new QFileSystemModel();
    projectFiles->setRootPath(QDir::currentPath());
    ui->filesTree->setModel(projectFiles);
    ui->filesTree->setRootIndex(projectFiles->index(QDir::currentPath()));

    // hide all but first column
    for (int i = 3; i > 0; --i)
    {
        ui->filesTree->hideColumn(i);
    }

That gives me a single column with “Name” header. How do I rename this header?

Answer 1

QAbstractItemModel::setHeaderData() should work. If not, you can always inherit from QFileSystemModel and override headerData().
