I am creating a subclass of QAbstractItemModel
to be displayed in an QTreeView
.
My index()
and parent()
function creates the QModelIndex
using the QAbstractItemModel
inherited function createIndex
and providing it the row
, column
, and data
needed. Here, for testing purposes, data is a Python string.
class TestModel(QAbstractItemModel):
def __init__(self):
QAbstractItemModel.__init__(self)
def index(self, row, column, parent):
if parent.isValid():
return self.createIndex(row, column, "bar")
return self.createIndex(row, column, "foo")
def parent(self, index):
if index.isValid():
if index.data().data() == "bar": <--- NEVER TRUE
return self.createIndex(0, 0, "foo")
return QModelIndex()
def rowCount(self, index):
if index.isValid():
if index.data().data() == "bar": <--- NEVER TRUE
return 0
return 1
def columnCount(self, index):
return 1
def data(self, index, role):
if index.isValid():
return index.data().data() <--- CANNOT DO ANYTHING WITH IT
return "<None>"
Within the index()
, parent()
, and data()
functions I need to get my data back. It comes as a QVariant
. How do I get my Python object back from the QVariant?
