Re: [nebula-dev] CalendarCombo + CDateTime Mashup

[Chris Gross <schtoo@xxxxxxxxxx>]

Hi Peter,

Hmm... I think your email points that we need some unification of our 
datetime widgets.  It sounds like you'd like to include the calendar 
popup from CalendarCombo with the date modification portion of 
CDateTime.  I wonder if you and Emil could work on something to 
completely combine the two widgets?

Is that something that sounds interesting to you Peter?  Emil?

Regards,
-Chris
