QTreeView/QDirModel persisting current directory selection

[bigduv]

Just to close this off I found a reasonable solution.
Calling setCurrentIndex() expands to the selected node.
Calling setExpanded() expands the selected node too.

class DirectoryTree : public QTreeView
{
public:
    void readSettings(QSettings& oSettings)
    {
        QString sLastSelection = oSettings.value("LastSelection").toString();
        if (!sLastSelection.isEmpty()) {
            QModelIndex index = m_oModel.index(sLastSelection);
            setCurrentIndex(index);
            setExpanded(index, true);
        }
    }
 
    void writeSettings(QSettings& oSettings) {
        oSettings.setValue("LastSelection", m_oModel.filePath(currentIndex()));
    }
 
protected:
    QDirModel& m_oModel;
};

class DirectoryTree : public QTreeView
{
public:
    void readSettings(QSettings& oSettings)
    {
        QString sLastSelection = oSettings.value("LastSelection").toString();
        if (!sLastSelection.isEmpty()) {
            QModelIndex index = m_oModel.index(sLastSelection);
            setCurrentIndex(index);
            setExpanded(index, true);
        }
    }

    void writeSettings(QSettings& oSettings) {
        oSettings.setValue("LastSelection", m_oModel.filePath(currentIndex()));
    }

protected:
    QDirModel& m_oModel;
};
