QAbstractTableModel and sort

[foxyproxy]

Hello, I have created my own QAbstractTableModel that uses. Now I have added the possibility to sort columns by using QSortFilterProxyModel. The problem is the model uses QList for adding new rows and when I sort a column the index between the model and QList doesnt match :S

How can I fix it? Can some1 help me pls?

Thank you for your help and suggestions

See QAbstractProxyModel::mapToSource() and QAbstractProxyModel::mapFromSource().

Thank wysota for your answer

Then I should reimplement those 2 methods. But what should they do? Sorting QList?

[wysota]

You shouldn't implement them. You should use them - they are already implemented in the proxy. The truth is you shouldn't need to use them but interface through the proxy instead of accessing the source model directly.

Sorry if I bug you but can you make an example to be more clear please? Thank you

How to use mapToSource

[wysota]

QModelIndex proxyIndex = ...
QModelIndex srcIndex = proxy->mapToSource(proxyIndex);

QModelIndex proxyIndex = ...
QModelIndex srcIndex = proxy->mapToSource(proxyIndex);
