Can mig calendar support subclasses of the Calendar object? We are looking into implementing a ComputedIslamicCalendar subclass of java.util.Calendar. We are interested in purchasing MigCalendar but require calendars other than Gregorian. Is this possible with MigCalendar?

Hello,

That's impossible to say unfortunately. It depends on which customizations you make to it. You'll have to test it.

Thanks,

I am looking on http://migcalendar.com/docs/javadoc/index.html and cannot find any way of setting a java.util.Calendar in the API. Can you direct me to the method that allow the setting of a java.util.Calendar that the MigCalendar will use?

It is using Calendar.getInstance(..) everywhere so no connection to a specific calendar type.

Thanks,

Ok, so what are my options:

1. You folks update MigCalendar to take a java.util.Calendar as input. As long as our custom class extends the java.util.Calendar base type I don't see this as a big issue.

2. Buy the source code and modify it ourselves to take a java.util.Calendar as input.

We'd like to buy your control but we cannot unless it supports Calendar types not returned by Calendar.getInstance(). Java (including 1.7) currently only has 3 sub classes of Calendar: java.util.Gregorian, sun.util.BuddhistCalendar, and java.util.JapaneseImperialCalendar.

Gregorian and Buddhist both seem to work with MigCalendar. Just set your locale on the command line for Buddhist.

java -Duser.language=th -Duser.region=TH AppFrame

JapaneseImperialCalendar gets an exception with the AppFrame example.

java -Duser.language=ja -Duser.country=JP -Duser.variant=JP AppFrame

Can you post the latest post as a support ticket?

From there it's easier to track the progress.
