[Moose-dev] RTCalendarBuilder

May I ask: Roassal and Pharo are really fantastic. I’m trying to get a grip on it and use it. What makes me think: In the introduction of the superb “Agile Visualization” book it is stated, that the Roassal OO approach allows for visualizations that are “easily extensible”. I guess compared to hand-crafted, imperative visualizations. Let’s take an example: RTCalendarBuilder I noticed that present visualization of week days start with Sunday as first day of week. E.g. in Europe/Germany weeks start on Monday (according ISO8601). We are visually so used to it, that other schemes make us think (not intuitive). How could I modify this? P.S.: Especially in calendrical visualizations there will be many (local) variations. So maybe it’s a good example to understand how to easily extend Roassal in above and similar topics as an interested user. BR Mike
