<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It's a problem. In theory parent could be another ProxyNode. - but we'll never call this method when parent isn't a GroupNode (in theory!)
I'll switch to dynamic_cast and try to stress test it.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Initial draft of a replacement for GroupsModel.
The key differences are:
- It doesn't rely on ContactModel* items, just a general model so can be used with the kpeople model as well as ours
- It can work on a tree (grouping by the top level items in the tree) for working with the kpeople model
- It can group on any property in the model. Not just GroupName. This will allow the KPeople model to still group by account.
- As it is generic it can also be used to provide the grouping in the LogViewer(for example), simplifying the entity model code there.
The code is pretty complex so I would like people to comment if it makes sense.
It is expected one subclasses this model for a specific purpose. i.e to group by groupNames:
QSet<QString> GroupGroupingModel::groupsForIndex(const QModelIndex &sourceIndex) const
{
QStringList groups = sourceIndex.data(AccountsModel::GroupsRole).value<QStringList>();
if (groups.isEmpty()) {
groups.append("_unsorted");
}
return groups.toSet();
}
QVariant GroupGroupingModel::dataForGroup(const QString &group, int role) const
{
switch (role) {
case Qt::DisplayRole:
if (group == "_unsorted") {
return i18n("Unsorted");
} else {
return group;
}
case AccountsModel::IdRole:
return group;
}
return QVariant();
}
Also if anyone can think of a better class name for something that group nodes by group name that isn't GroupGroupingModel that would be much appreciated.

Tested with ContactsModel->FlatModelProxy->This
Tested grouping by GroupName, by account, by client type, and grouping by presence.
In the near future ContactsModel will be a list, so this makes more sense.
No crashes, everything appeared to work.</pre>
