c++ - QByteArray to QString

Question

I'm having issues with QByteArray and QString.

I'm reading a file and stores its information in a QByteArray. The file is in unicode, so it contains something like: t e s t

I'm trying to compare this value to my specified value, but it fails, because in the debugger I see it's not an unicode string.

The code will explain everything:

QByteArray Data; //contains unicode string "t e s t  "
QString myValue = "test"; //value to compare.
if(Data.contains(myValue))
    //do some stuff.
else
    //do other stuff.

In the debugger, it shows me that the variable Data has the value "t e s t " and myValue has the value "test". How can I fix it?

You can use this QString constructor for conversion from QByteArray to QString:

QString(const QByteArray &ba)

QByteArray data;
QString DataAsString = QString(data);
