[Interest] QTemporaryFile::open()

[Mike Chinander]

See: http://doc.qt.io/qt-5/qtemporaryfile.html#open

"A QTemporaryFile will always be opened in QIODevice::ReadWrite mode, this
allows easy access to the data in the file. This function will return true
upon success and will set the fileName() to the unique filename used."
