How to I use filterAcceptsRow() function ?

tako

Don't give me url. Only view sample code with filterAcceptsRow().

http://doc.qt.io/qt-5/qsortfilterproxymodel.html#details

It is a URL but if you read it under the sub heading "Filtering" you will see a code example.

Here is a sample from something I'm working on. It accepts only rows where the string _search is contained in one of the specified columns.

sample.h

class StatusFilter : public QSortFilterProxyModel
{
public:
    explicit StatusFilter(QObject * parent = 0);
    ~StatusFilter()= default;

    void setSearch(const QString &str) noexcept;

private:
    QString _search;

    bool filterAcceptsRow(int source_row, const QModelIndex &) const override;
};

sample.cpp

bool StatusFilter::filterAcceptsRow(int source_row, const QModelIndex &) const
{
    QStringList sl= _search.split(QRegExp("[ ,]+"),QString::SkipEmptyParts);
    for (auto const &s:sl)
    {
        bool found= false;
        for (int col:
            {
                static_cast<int>(STATUS_COLUMN::RMA_NUMBER),
                static_cast<int>(STATUS_COLUMN::CUSTOMER_NAME),
                static_cast<int>(STATUS_COLUMN::LOCATION),
                static_cast<int>(STATUS_COLUMN::NOTES)
            })
        {
            QModelIndex ix= sourceModel()->index(source_row,col);
            QString str= ix.data().toString().toLower();
            if (str.contains(s))
                return true;
        }
    }
    return false;
}

void StatusFilter::setSearch(const QString &str) noexcept
{
    _search= str.toLower();
    invalidate();
}

Your question lacks detail. If you're having a problem understanding how filterAcceptsRow() works, please supply something you've tried and the problem you're having with it.
