So, we should definitely put whatever we use in a wrapper function, because:
1. That way, it's easy to fix whatever we wrote if we run into some corner case where it doesn't work.
2. From Qt 5.4 onwards, one can write:
QUrl::fromUserInput(arg, QDir::currentPath(), QUrl::AssumeLocalFile)
(see http://doc-snapshot.qt-project.org/qt5-5.4/qurl.html#fromUserInput-2)
which should do exactly what we want. (Unfortunately, that overload is new in 5.4. Thanks to Lukáš Tinkl for pointing me to it.)
The exact code Qt 5.4 uses is:
https://qt.gitorious.org/qt/qtbase/commit/31ce6f50c679e61dc53f09ee1b1637918da38a82
If we're writing a function anyway, we may as well use that logic, as in:
```c++
QUrl urlFromArg(const QString& arg)
{
#if QT_VERSION >= 0x050400
return QUrl::fromUserInput(arg, QDir::currentPath(), QUrl::AssumeLocalFile);
#else
// Logic from QUrl::fromUserInput(QString, QString, UserInputResolutionOptions)
QUrl testUrl = QUrl(arg, QUrl::TolerantMode);
if (testUrl.isRelative() && !QDir::isAbsolutePath(arg)) {
QFileInfo fileInfo(QDir::current(), arg);
return QUrl::fromLocalFile(fileInfo.absoluteFilePath());
}
return QUrl::fromUserInput(arg);
#endif
}
```
(Okular is doing something similar, as pointed out by Lukáš.)
Please note that I definitely want AssumeLocalFile, even where we don't need to accept files that don't exist, because I don't want Kompare to do a hostname lookup if it's passed a nonexisting file, I think it doesn't make any sense to assume a URL if no http:// is given.
