QTableView + sorting + numbers & special characters

[Lykurg]

Second problem:
In 3'rd column data is text type and has lithuanian characters (ĄČĘĖĮÅ ŲŪŽ) (if you don't see the characters set character encoding on your browser Baltic (Windows-1257)). When I'm sorting data using this column then data sorts something like that [A,B,C,D,E,F,G,...,ĄČĘĖĮ,...]. In lithuanian language sorting of text with lithuanian characters is [A,Ą,B,C,Č,D,E,Ę,Ė,F,G,...]

Subclass your model and alter QAbstractItemModel::sort();

and

item = new QStandardItem(tr("%0").arg(query->record().value("kk").toString()));

item = new QStandardItem(tr("%0").arg(query->record().value("kk").toString()));

To copy to clipboard, switch view to plain text mode 

could be easily written as

item = new QStandardItem(query->record().value("kk").toString());

item = new QStandardItem(query->record().value("kk").toString());

To copy to clipboard, switch view to plain text mode
