different source colours or prefixes

[fnetX]

Hey,

When using multiple calendar sources, it might be a nice idea to specify keep them distinguishable, e.g. by using different (background / highlight) colours or prefixes for each of them.

There seems to be an in official attribute for color: X-APPLE-CALENDAR-COLOR

BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
PRODID:-//SabreDAV//SabreDAV//EN
X-WR-CALNAME:chaostreff-potsdam
X-APPLE-CALENDAR-COLOR:#CACBCD
END:VCALENDAR

This seems to be used by nextcloud

Pardon my ignorance but how would you add that?

[niccokunzmann]

Each event goes through Javascript. That could be the place. Also, the attribute might need to be copied over from the Python event object into the JSON data that is sent to the website by flask.

@niccokunzmann : I have now added the above attribute but still no change in the calendar colors... Am I missing something?

+1 for this. I'm working with Outlook calendars, and I don't think I can add colours to the calendars themselves, but I'd like to be able to distinguish between different calendars that have been imported into the view.

Going off the DHTMLX docs, and having had a quick nose through the codebase, am I right in thinking that adding the following line or similar to the return statement at /convert_to_dhtmlx.py:42 would at least get the background colour changing for coloured events?

"color": calendar_event.get("X-APPLE-CALENDAR-COLOR", ""),

Additionally, the below line might be needed:

"textColor": "#ffffff",

assuming that the calendar program has provided colours with high enough contrast from white.

I am happy to receive a pull request for that. It could be simple and I guess If it creates unexpected behavior, we will hear back. Am 24. März 2022 16:37:42 GMT+00:00 schrieb Barnaby Collins ***@***.***>:

As linked in the Pull Requests above, now you can change the color of the calendars.
