Hello,
I think I have fallen into a Qt bug but perhaps I am wrong.
According to the (latest) Qt documentation,
QAbstractItemModel.createIndex takes a uint32 as the model index
internalId, while the internalId() method of QModelIndex returns a
uint64. I guess my problems are coming from that inconsistency.
The problem is illustrated below. On a windows machine and on a 64-bit
linux machine everything is fine.
On a 32-bit linux machine the given internalId (= id(a) ) and the
returned internalId are not the same. In fact, one of them is negative.
Both, the linux-32 machine and the windows XP machine are running sip
4.7.9, PyQt 4.4.4 and qt 4.4.3
Am I missing some obvious solution to the problem?
Best regards,
Armando
import PyQt4.Qt as qt
class Model(qt.QAbstractItemModel):
def index(self, row, column, parent):
a=[" Hello World"]
index = self.createIndex(row, column, id(a))
print "Next two values should be the same"
print "indexInternalId = ", index.internalId()
print "id(a) = ", id(a)
return index
if __name__ == "__main__":
app = qt.QApplication([])
w = Model()
w.index(0,0,None)
