Right. Thanks for pointing out that I still need to explicitly pass
"self."
I'm still not getting checkboxes displayed in the tree widget,
though. I
believe the problem is in the nested return value in the model's
data()
method.
The C++ example code I'm following uses a QMap data structure to hold
checkState values. After reading Assistant notes, a python
dir(QtCore),
and some googling, I've found that QMap is not implemented in
PyQt. So
I'm using a Dict instead. Still, my app complains:
TypeError: invalid result type from DirModel.data()
Here's the C++ code I'm following:
virtual QVariant data(const QModelIndex &index, int role =
Qt::DisplayRole) const
{
if (role == Qt::CheckStateRole && index.column() == 0) {
return
checkstates.value(fileInfo(index).absoluteFilePath(),
Qt::Unchecked);
You need to wrap that in a QVariant, i.e.
return QVariant(....)
data() needs to return a QVariant and Python doesn't support the
implicit constructors as C++ does.
