Reading from QFile when QTextStream is open

[dawwin]

I use

QTextStream in(stdin, QIODevice::ReadOnly)

QTextStream in(stdin, QIODevice::ReadOnly)

To copy to clipboard, switch view to plain text mode 

To read text from standard input. But I need getChar() function to block execution until user press enter so i need to open

file.open(stdin, QIODevice::ReadOnly);

file.open(stdin, QIODevice::ReadOnly);

To copy to clipboard, switch view to plain text mode 

Is this ok to call QFile::getChar when file is already open in QTextStream?
