Hi
I've found something rather odd that happens when sorting in a
QSortFilterProxyModel with datetime.date datatypes. If I call sort()
on a column containing datetime.date values, it doesn't appear to do
anything. If I then call sort on another column, then on the first
column again, it works. I am using python 3.2 and PyQt 4.8.3 on
Windows XP. I haven't tried this on any other platform. Does anyone
else get this behaviour?
The following code shows illustrates the problem:
from datetime import date
from PyQt4.QtCore import QAbstractTableModel, Qt, QDate
from PyQt4.QtGui import QSortFilterProxyModel
class Model(QAbstractTableModel):
def rowCount(self, parent=None):
return 4
def columnCount(self, parent=None):
return 2
def data(self, index, role):
if role != Qt.DisplayRole:
return super().data(index, role)
values = [(11, date(2011, 1, 1)),
(10, date(2010, 1, 1)),
(14, date(2014, 1, 1)),
(5, date(2005, 1, 1))]
return values[index.row()][index.column()]
model = Model()
sortModel = QSortFilterProxyModel()
sortModel.setSourceModel(model)
col = 1
print("These should be sorted, but aren't")
sortModel.sort(col)
for row in range(4):
print(sortModel.data(sortModel.index(row, col), Qt.DisplayRole))
print("Now they are sorted")
sortModel.sort(0)
sortModel.sort(col)
for row in range(4):
print(sortModel.data(sortModel.index(row, col), Qt.DisplayRole))
