When I run following code (of course with some implementation of tree objects):
class QCategorizedItemModel(QAbstractItemModel):
def __init__(self, tree):
QAbstractItemModel.__init__(self)
self.__root = tree
def root(self):
return self.__root
def columnCount(self, parent):
# there is only one column with all categories inside
return 1
def rowCount(self, parent):
return parent.internalPointer().childrenCount()
def flags(self, index):
if not index.isValid():
return 0
return Qt.ItemIsSelectable
def index(self, row, column, parent):
if column != 0:
return QModelIndex()
child = parent.internalPointer().child(row)
if child:
return self.createIndex(row, column, child)
else:
return QModelIndex()
def parent(self, index):
internal = index.internalPointer()
if internal == self.__pointer:
return QModelIndex()
return createIndex(internal.childNumber(), 0, internal)
it displayed an empty tree view and didn't shout about the need of
subclassing data method, which is pure virtual. I don't know it that's
a problem.
