Hi developers of finance apps & Calligra Sheets & Calligra Plan, (please keep cross-posting to both ml for now)
I (not only with my Calligra developer hat on) would like to collect experiences and ideas for conversion of curreny values to and from strings when using Qt5/KF5, especially when porting from kdelibs4's KLocale. PROBLEM QLocale is rather limited (as of Qt 5.5): - no currency string parsing method - string formatting method toCurrencyString() does not allow to control precision KLocale and its currency related methods seem the last blocker to get rid of kdelibs4support in Calligra in the Qt5/KF5 port. Plan uses them for handling the costs of resources, and Sheets for the currency formatted cells. And both limitations are a blocker. APPROACHES Long term ideally QLocale gets support in its API for that. So we developers of currency data handling software should organize and draft an API. First and short term though, until some released & wide-spread Qt version has the improved QLocale, I am looking for a solution independent of QLocale. Most obvious might be to duplicate all currency things from KLocale, which would also include duplicating the database with all currency formatting data. This is what I would plan to do if there is no better idea. Especially the database duplication is painful though, I would like to avoid at least that if possible. QUESTIONS How have developers of e.g. Skrooge & KMyMoney approached the issue of conversion of currency values to/from strings? Do you know about any activities to improve QLocale here? Seems that Calligra apps Plan & Sheets are the only KDE apps using KLocale::readMoney() ? https://lxr.kde.org/ident?v=stable-qt4&_i=readMoney&_remember=1 But KLocale::formatMoney() might be used by KMyMoney, Skrooge, Kraft & others (did not check though if not custom code): https://lxr.kde.org/ident?v=stable-qt4&_i=formatMoney&_remember=1 Cheers Friedrich _______________________________________________ calligra-devel mailing list calligra-devel@kde.org https://mail.kde.org/mailman/listinfo/calligra-devel
