Qt - custom decimal point and thousand separator

Question

How can I convert a number (double) to string, with custom decimal point and thousand separator chars?

I\'ve seen QLocale, but I don\'t want to choose the localization c

Answer 1

Qt doesn't support custom locale. But to deal with just group and decimal point characters is trivial:

const QLocale & cLocale = QLocale::c();
QString ss = cLocale.toString(yourDoubleNumber, 'f');
ss.replace(cLocale.groupSeparator(), yourGroupChar);
ss.replace(cLocale.decimalPoint(), yourDecimalPointChar);

BTW, spbots' question is not irrelevant. More detail about the goal always helps and it could lead to different approach that may serve you better.
