How to join 2 QList and filter by QString ?

sonichy

QDir dir1(path1);
QFileInfoList list1 = dir1.entryInfoList();
QDir dir2(path2);
QFileInfoList list1 = dir2.entryInfoList();
// How to add 2 QList and filter by member
QFileInfoList list3 = list1 + list2;
list3.filter(QFileInfoList::FileName, "dde")

I swear I'm not writing this horror on purpose

QFileInfoList list3;
list3.reserve(list1.size()+list2.size());
for(const QFileInfoList& singleList : {qAsConst(list1),qAsConst(list2)})
std::copy_if(singleList.cbegin(),singleList.cend(),std::back_inserter(list3),[](const QFileInfo& fileInfo)->bool{return fileInfo.fileName().contains(QStringLiteral("dde"),Qt::CaseInsensitive);});

QFileInfoList listSearch;
QDir dir1(path1);
QFileInfoList list1 = dir1.entryInfoList();
QDir dir2(path2);
QFileInfoList list1 = dir2.entryInfoList();
QFileInfoList list3 = list1 + list2;

void MainWindow::search(QString text)
{
    listSearch.clear();
    for (int i=0; i<list3.size(); i++) {
        QFileInfo fileInfo = list3.at(i);
        if (fileInfo.fileName().contains(text,Qt::CaseInsensitive)) {
            listSearch.append(fileInfo);
        }
    }
