I was unable to allocate a minimum example. Here is pseudocode situations:
[code]
class BaseData(QObject):
def save(self, obj):
self.emit(QtCore.SIGNAL('datat_change'), obj)
class Model(QAbstractItemModel):
def __init__(self, data):
# data Mast be derived from BaseData
self.connect(
data, QtCore.SIGNAL('data_change'), self.__data_changes)
def __data_changes(self, arg):
row = self.__getRowForArg(arg)
ind = self.createIndex(row, 0, self.objects[row]) #!!! RuntimeError
class Mixin(object):
data = None #Mast be derived from BaseData
result = None #Setup brfore accept()
def __init__(self, ...):
...
def initUi(self):
ui = self.__ui = Ui_DlgFrame()
ui.setupUi(self)
model = self.__model = self.Model(self.dataCls.singleton())
ui.tableView.setModel(model)
class DlgFrame(QDialog, Mixin):
def __init__(self, data, parent=None, ...):
QDialog.__init__(self, parent)
Mixin.__init__(self, ...)
self.initUi()
@classmethod
def getRes(cls, parent ...):
frm = cls(parent, ...)
if frm.exec_() == QtGui.QDialog.Accepted:
return frm._result
return None
class FinalDlg(DlgFrame, ...):
# This class generated by function 'type'
dataCls = FinalData #Derived from BaseData
class Main(QMainWindow):
def __init__(self):
data = FinalData.singleton()
@QtCore.pyqtSignature('')
def on_btGetRes_clicked(self):
self.res = FinalDlg.getRes(self, ...)
@QtCore.pyqtSignature('')
def on_btSaveRes_clicked(self):
self.data.save(self.res)
[/code]
Scenario for reproduction:
start Application
press btGetRes
press btSaveRes
In PyQt-win-gpl-4.5-snapshot-20090419.zip error also.
