Public bug reported:
I wanted to replace a custom C++ model in webbrowser-app by a QML
SortFilterModel. My custom model simply does sorting by descending order
on a given role, but this didn’t work. I figured out the reason for
this: the source model being sorted has custom roles, and their keys
don’t start at 0. They are defined using an enum like so:
enum Roles {
Domain = Qt::UserRole + 1,
LastVisit,
LastVisitDate,
LastVisitedTitle,
LastVisitedIcon,
Entries
};
(see http://bazaar.launchpad.net/~phablet-team/webbrowser-
app/trunk/view/head:/src/app/webbrowser/history-domainlist-model.h#L42
and http://bazaar.launchpad.net/~phablet-team/webbrowser-
app/trunk/view/head:/src/app/webbrowser/history-domainlist-
model.cpp#L48).
The implementation of SortFilterModel has a
QSortFilterProxyModelQML::roleByName() method which incorrectly assumes
that role keys start at 0 (see http://bazaar.launchpad.net/~ubuntu-sdk-
team/ubuntu-ui-
toolkit/trunk/view/head:/src/Ubuntu/Components/plugin/sortfiltermodel.cpp#L112).
This method should be fixed to account for custom keys.
