Set alignment for QTreeView cells

Re: Set alignment for QTreeView cells

QTreeView Cell Alignment

QStandardItem:: setTextAlignment(Qt::Alignment)

so

my_model ->item(row, column)->setTextAlignment(Qt::AlignCenter);

Please suggest me if there is another way.

@LeeHyunKyu
Why do you want another way?

I don't know if that is a question. The way Qt works is that alignments etc. are on a cell-by-cell basis, not a complete row/column. That's just how it is. However, using Qt data() way of doing things, among the roles (https://doc.qt.io/qt-5/qt.html#ItemDataRole-enum) there is e.g. Qt::TextAlignmentRole, so one can write code to affect all cells in a row/column via that return result instead of actually setting alignment on individual cells.

@Denni-0 said in Set alignment for QTreeView cells:

but I know you can affect an entire column and/or row within a QTreeView as I have done it but cannot find it now

You would look at index.row() or index.column() to affect row/column:

    def data(self, index, role):
        if (role == QtCore.Qt.TextAlignmentRole):
            if index.row() == whatever or index.column() == something:
                return QtCore.Qt.AlignHCenter

Hi,

You can use a QIdentityProxyModel between your orignal data and your view. You can alter there just what you want.
