How to get the MIME type of a file in Qt?

Question

Is there a way to get the MIME type of a file in Qt?

I am writing an application that needs to find the MIME type of a given file.

Answer 1

Qt 5 has added support for MIME types:

http://doc.qt.io/qt-5/qmimedatabase.html

QString path("/home/my_user/my_file");
#if QT_VERSION >= QT_VERSION_CHECK(5, 0, 0)
    QMimeDatabase db;
    QMimeType type = db.mimeTypeForFile(path);
    qDebug() << "Mime type:" << type.name();
#endif

Answer 2

#include <QMimeDatabase>  

QString mimeType( const QString &filePath ){ return QMimeDatabase().mimeTypeForFile( filePath ).name(); }

Answer 3

You need to use 3rd party libraries for this purpose, there is no mime-type guessing support in Qt itself. On Linux/Unix you could use libmagic.
