QStringList, how to access elements after getOpenFileNames

[wrdieter]

How do I access the individual strings in a QStringList that was created using getOpenFileNames?

QStringList fileNames;
fileNames = QFileDialog::getOpenFileNames(this,"Select File(s) to search","/home");

To assign the ith filename to fn:

QString fn = fileName.at(i)

QString fn = fileName.at(i)

To copy to clipboard, switch view to plain text mode 

You can write a straightforward for loop to iterate through the QStringList. The number of elements in the fileNames QStringList will be fileNames.size().

Or you can use

QStringList list = QFileDialog::getOpenFileNames(...);
foreach (QString s, list) {
    // do some useful stuff here
    qDebug() << "Working on file " << s;
}

QStringList list = QFileDialog::getOpenFileNames(...);
foreach (QString s, list) {
    // do some useful stuff here
    qDebug() << "Working on file " << s;
}

To copy to clipboard, switch view to plain text mode 

provided you have keywords enabled. The foreach functionality will be available as Q_FOREACH in any case.

offtop, it's better to use const refs in foreach, you can take a look on this tests.
