custom model + PyQt4

[wirasto]

Someone give me a sample code

def data(self, index, role):
   value=QSqlQueryModel.data(self, index, role)
   if role == Qt.TextAlignmentRole:
       if (index.column()==2):
              return QVariant(Qt.AlignRight)
   return value

def data(self, index, role):
   value=QSqlQueryModel.data(self, index, role)
   if role == Qt.TextAlignmentRole:
       if (index.column()==2):
              return QVariant(Qt.AlignRight)
   return value

To copy to clipboard, switch view to plain text mode 

i hope can be useful for others

And your sample, the same as that in there. But unfortunately code like that do not display data.

That's because it is only a part out of the whole function. You have to respect the other roles by yourself or - as below - call the base class.

def data(self, index, role):
   value=QSqlQueryModel.data(self, index, role)
   if role == Qt.TextAlignmentRole:
       if (index.column()==2):
              return QVariant(Qt.AlignRight)
   return value

def data(self, index, role):
   value=QSqlQueryModel.data(self, index, role)
   if role == Qt.TextAlignmentRole:
       if (index.column()==2):
              return QVariant(Qt.AlignRight)
   return value

For speed and performance issues you should better use:

def data(self, index, role):
  if role == Qt.TextAlignmentRole:
    if (index.column()==2):
      return QVariant(Qt.AlignRight)
  return QSqlQueryModel.data(self, index, role)

def data(self, index, role):
  if role == Qt.TextAlignmentRole:
    if (index.column()==2):
      return QVariant(Qt.AlignRight)
  return QSqlQueryModel.data(self, index, role)
