How to translate string in ListElement?

owenzhao

@ListElement {
logColor: "darkgrey"
log: qsTr("This is a long sentence.")
}@
and I got the error code
@ListElement: cannot use script for property value @

Any ideas?
Thank you.

I will consider implementing a model using C++ that will store the strings to translate. (I have done this for displaying a list with settings entries that have to be translated)

Header
@
class MyModel : public QAbstractListModel
{
Q_OBJECT
Q_PROPERTY(int count READ count NOTIFY countChanged)
public:
enum SelectorRole {
TextRole
};
explicit MyModel(QObject *parent = 0);
virtual int rowCount(const QModelIndex &parent = QModelIndex()) const;
int count() const;
virtual QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const;
Q_SIGNALS:
void countChanged(int count);
public Q_SLOTS:
void addEntry(const QString &text);
private:
QStringList _items;
};
@

Implementation
@
MyModel::MyModel(QObject *parent) :
QAbstractListModel(parent)
{
// Definition of roles
QHash <int, QByteArray> roles;
roles.insert(TextRole, "text");
setRoleNames(roles);
}

int MyModel::rowCount(const QModelIndex &parent) const
{
Q_UNUSED(parent)
return _items.count();
}

int MyModel::count() const
{
return rowCount();
}

QVariant MyModel::data(const QModelIndex &index, int role) const
{
if (index.row() < 0 or index.row() >= rowCount())
{
return QVariant();
}

switch(role) {
case TextRole:
    return _items.at(index.row());
    break;
default:
    return QVariant();
    break;
}

}

void SelectorModel::addEntry(const QString &text)
{
beginInsertRows(QModelIndex(), rowCount(), rowCount());

_items.append(text);

emit countChanged(rowCount());
endInsertRows();

}
@

And declare it in QML using

@
qmlRegisterType<MyModel>(uri, 1, 0, "MyModel");
@

Finally, invoke it in QML with

@
MyModel {
id: model
Component.onCompleted {
addEntry(qsTr("First entry with translation"))
addEntry(qsTr("Second entry with translation"))
}
}
@

PS : It seems that in Qt4.8 there are some impouvements :
