[SailfishDevel] QT String issue

[Martin Kampas]

Hi Dylan,

The backslashes you see in the output are only added when you print the string, not actual characters of the string:

"\"Intex Aqua Fish\""

So what you need is to replace just the doublequotes - try data.replace("\"", "") or better data.remove('"').

BR,
Martin

Hi Dmitriy,

For some reason, it doesn't work...

QString data = line.split('=', QString::SkipEmptyParts).at(1);

data.replace("\\\"", "");

dataList.append(qMakePair(querry, data));

This is my code now, but the result is still the same for some reason.
I think I do something still wrong :(

Cheers,
Dylan

Hi Dmitriy,

Thanks for the information! I just started to learn QT C++ :)

Cheers,
Dylan

Hi Dylan,
trimmed() removes whitespaces only. You need to replace \" with an empty string and "escape" both \ and ". You need escaping because this is how string literals in C/C++ work. Try calling str.replace("\\\"", ""), where str an object of QString.

Also note that trimmed() is a const method and does not change the object for which it was called. I.e.

QString str1 = "  a  ";
str1.trimmed();
// str1 is unchanged but returns a QString object which is "a"

Cheers
Dmitriy

Hi,

I'm reading the sfos-release and the hw-release file in /etc from C++ but for some lines I get this in my strings as output:




"\"Intex Aqua Fish\""

I tried trimmed() and remove() but I can't figure out how to clean it correctly. The \" characters are annoying.

Kind regards,
Dylan Van Assche
