Custom QAbstractProxyModel

[alizadeh91]

Thanks wysota, Yes i'm reading! i just want to clear the problem!

If you wish to modify values returned by the model, reimplement data().

Thanks again wysota, I've implemented the data() and it's ok except that the table doesn't update itself when i modify values returned by the model. I've even
try emit dataChanged() signal but i'm getting a weird error:

error: C2662: 'QAbstractItemModel::dataChanged' : cannot convert 'this' pointer from 'const TCustomProxyModel' to 'QAbstractItemModel &'
Conversion loses qualifiers

error: C2662: 'QAbstractItemModel::dataChanged' : cannot convert 'this' pointer from 'const TCustomProxyModel' to 'QAbstractItemModel &'
Conversion loses qualifiers

To copy to clipboard, switch view to plain text mode 

(TCustomProxyModel: my custom proxy model)

Just another thing: when i click on table the table update itself!!!

You can't emit dataChanged() from data() which is a const method. Invalidate the proxy model when its data changes (that is when you perform action that will cause the proxy to return different values).
