Hello, I'd like to add an "alternate calendar system" to KDE's calendar applet, which, for example, will be able to allow users set to display a Chinese Lunar Calendar in the same MonthView as the main Gregorian calendar dates. Then QCalendar seems to be a good choice to use, then I found there are some questions related to the API of QCalendar, and would like to discuss it here, hope I come to the right place, please let me know if not.
The first issue is, in order to get QCalendar support a new calendar system, it seems like I need to subclass QCalendarBackend first, which is a private Qt API. Is that correct? If so, is there any plan to make it public? If not, I hope there can be a way to add custom calendar systems in a way similar to what Qt's imageformats plugin does. The second issue is, for example, Traditional Chinese calendar have their own (localized) day name, the first day of a month names "初一" and the 22nd day of the month names "廿二". It seems there are functions that can be used to get the localized month name and weekday name, but seems there is no function provided to get a localized day name. Is that correct? If so, can we add such a feature to QCalendar? Also, currently, QCalendar doesn't seem to be able to get the Cyclic year name and also get to know if the given month is leap month. I'm not sure if it's by design since QCalendar::monthName() mentioned that issue. Then it seems we are able to get the localized month name which can indicate it's a leap month or not to the user, but not able to know if it's a leap month from the API. By the way, is there any plan to introduce the Chinese calendar system support in official Qt release? That's all that I want to ask now. Thanks for reading and have a nice holiday :) Gary Wang --- btw, some link related to this feature discussion: plasma-devel discussion thread: https://mail.kde.org/pipermail/plasma-devel/2020-December/118960.html KDE bug tracker: https://bugs.kde.org/show_bug.cgi?id=429892 _______________________________________________ Development mailing list [email protected] https://lists.qt-project.org/listinfo/development
