Application aborts when QSaveFile is passed to Document::saveAs(QIODevice *device)

[Talkless]

Try passing QSaveFile to Document::saveAs(QIODevice *device). Application will abort due to:

qFatal("QSaveFile::close called");

(see https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/io/qsavefile.cpp?h=v6.10.2#n267)

Documentation states:

Unlike QFile, calling close() is not allowed. commit() replaces it.

so why using QSaveFile,try QFile instead
