So does this module need an API for determining mime type from data? e.g. something like: static QMimeType determineMimeType(QIODevice* device, QString fileNameHint); static QMimeType determineMimeType(QFile file); //convenience wrapper for common case Given a known filename, the type can be guessed if the extension is unambiguous (e.g. "picture.jpg" is probably "image/jpeg") Given an unknown filename or ambiguous extension, the type can be guessed by reading & parsing the file header (e.g. a binary file with "JFIF" in the right place in the first 16 bytes is probably "image/jpeg") There are some edge cases e.g. a file called "image.jpg" that actually contains data of the "image/tiff" type. Also, the IO device may be unavailable (e.g. you have the filename but no permission to open the file) Or the file name may be unknown (e.g. you don't have a file, just a data stream from the network) ________________________________ This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.
