[PyQt] vertical alignment of richtext in a table view

[Wolfgang Rohdewald]

Hi,

in Mark Summerfields book "Rapid GUI programming with Python
and QT", there is an example on page 485 with a table column
having a delegate that displays richtext. In the book,
the text in this column has a vertical alignment in the middle
of the cells, just like the other columns.

but if I execute that example (from the downloadable source:
chap16/carhirelog.pyw), the rich text is vertically not 
in the middle but above. How can I make it align vertically
just like a normal column?

His book has another such table chap14, page 436 /
ships_delegate.pyw.
Here, both the image in the book and the executable show
the same wrong vertical alignment.

BTW interesting things happen if the column with richtext
is resized to a minimum: the delegate draws outside of its
available horizontal space, showing text to the right of
the rightmost column.

(using pyqt 4.7.3 with qt4-4.7.0-rc1)

this is the paint of the delegate:

    def paint(self, painter, option, index):
        text = index.model().data(index, Qt.DisplayRole).toString()
        palette = QApplication.palette()
        document = QTextDocument()
        document.setDefaultFont(option.font)
        if option.state & QStyle.State_Selected:
            document.setHtml(QString("<font color=%1>%2</font>") \
                    .arg(palette.highlightedText().color().name()) \
                    .arg(text))
        else:
            document.setHtml(text)
        painter.save()
        color = palette.highlight().color() \
            if option.state & QStyle.State_Selected \
            else QColor(index.model().data(index,
                    Qt.BackgroundColorRole))
        painter.fillRect(option.rect, color)
        painter.translate(option.rect.x(), option.rect.y())
        document.drawContents(painter)
        painter.restore()
