Read binary file and convert to QString

[patrik08]

I have a binary file but I do not know what is written in it.
How do I read a binary file byte to byte and convert to String (QString)?
I do not know how this file is formatted, so it must convert this file to text.
Thanks.

Each binary file having a signature.... / QDataStream having a nummer (on my case!)

This function was introduced in Qt 4.1.

QIODevice::peek(4).contains("PNG");   /* pngimage */
QIODevice::peek(4).contains("GIF");   /* gifimage */
QIODevice::peek(4).contains("MZ");   /* executable */
 
QIODevice::peek(4).contains("<");   /* xml.xhtml, or xmldialect  and open as text */

QIODevice::peek(4).contains("PNG");   /* pngimage */
QIODevice::peek(4).contains("GIF");   /* gifimage */
QIODevice::peek(4).contains("MZ");   /* executable */

QIODevice::peek(4).contains("<");   /* xml.xhtml, or xmldialect  and open as text */

To copy to clipboard, switch view to plain text mode 

replace QIODevice by QFile or what else...
