Updated for PyQt5

from PyQt5.QtCore import Qt, QAbstractProxyModel, QModelIndex, QSortFilterProxyModel

class HorizontalProxyModel(QAbstractProxyModel):
    """Rotates model 90 degrees"""

    def __init__(self, src, parent=None):
        super(HorizontalProxyModel, self).__init__(parent)
        self.setSourceModel(src)

    def mapToSource(self, proxyIndex: QModelIndex) -> QModelIndex:
        if self.sourceModel():
            return self.sourceModel().index(proxyIndex.column(), proxyIndex.row())
        else:
            return QModelIndex()

    def mapFromSource(self, sourceIndex: QModelIndex) -> QModelIndex:
        return self.index(sourceIndex.column(), sourceIndex.row())

    def index(self, row: int, column: int, parent: QModelIndex = ...) -> QModelIndex:
        return self.createIndex(row, column)

    def parent(self, child: QModelIndex) -> QModelIndex:
        return QModelIndex()

    def rowCount(self, parent: QModelIndex = ...) -> int:
        return self.sourceModel().columnCount() if self.sourceModel() else 0

    def columnCount(self, parent: QModelIndex = ...) -> int:
        return self.sourceModel().rowCount() if self.sourceModel() else 0

    def headerData(self, section: int, orientation: Qt.Orientation, role: int = ...) -> typing.Any:
        if not self.sourceModel():
            return None
        new_orientation = Qt.Vertical if orientation == Qt.Horizontal else Qt.Horizontal
        return self.sourceModel().headerData(section, new_orientation, role)
