How do I convert a QStyleOptionViewItem into a QStyleOptionViewItemV4? Qt
has the qstyleoption_cast() method, but no such method exists in PyQt4.
I have my own subclass of QStyledItemDelegate and have overridden the
initStyleOption() method so that I can provide my own foreground/background
colors, fonts, etc. The problem I'm running into is with the background
color -- I need to set the backgroundBrush attribute, which is only
available on QStyleOptionViewItemV4. So I need to somehow cast the
QStyleOptionViewItem object into a QStyleOptionViewItemV4 object...
from PyQt4 import *
class MyItemDelegate(QStyledItemDelegate):
def initStyleOption(self, option, index):
QStyledItemDelegate.initStyleOption(self, option, index)
# set font family and color
option.font.setFamily("Courier")
option.palette.setBrush(QPalette.Text, QtCore.Qt.red)
# set background color
# this doesn't work:
option.backgroundBrush = QBrush(QtCore.Qt.black)
# neither does this:
option = QStyleOptionViewItemV4(option)
option.backgroundBrush = QBrush(QtCore.Qt.black)
