Update QAbstractTableModel?

[adutzu89]

I made use of QAbstractTableModel to show data retrieved through QNetworkAccessManager in a QTableView, it works well, the only issue is that if the data is changed the model doesn't "refresh" until I click on the tableview or scroll through the table.

header:

class ModelLClienti:public QAbstractTableModel{
    Q_OBJECT
public:
    ModelLClienti(QObject *parent=0);
 
    int rowCount(const QModelIndex &parent) const;
    int columnCount(const QModelIndex &parent) const;
    QVariant data(const QModelIndex &index, int role) const;
    QVariant headerData(int section, Qt::Orientation orientation, int role) const;
    void setLista(QList<QString> lista);
private:
    QList<QString> listaCli;
};

class ModelLClienti:public QAbstractTableModel{
    Q_OBJECT
public:
    ModelLClienti(QObject *parent=0);

    int rowCount(const QModelIndex &parent) const;
    int columnCount(const QModelIndex &parent) const;
    QVariant data(const QModelIndex &index, int role) const;
    QVariant headerData(int section, Qt::Orientation orientation, int role) const;
    void setLista(QList<QString> lista);
private:
    QList<QString> listaCli;
};

I need to change the data inside the model and afterwards, show in the tableview.

When you change data in the model, you have to emit dataChanged() signal for the index range that gets changed.

Thank you, I managed it.
