TsgcHTMLComponent_ActivityFeed — render a live, newest-first activity feed with relative timestamps and out-of-band WebSocket push, in Delphi, C++ Builder and .NET.
Push activities with AddActivity, read HTML for the first render, then push new items live with a WebSocket fragment.
TsgcHTMLComponent_ActivityFeed
Bootstrap 5 list + scoped CSS + live relative-time script
Delphi, C++ Builder, .NET
Call AddActivity for each entry, read HTML for the initial page, then push a new item as an out-of-band fragment over WebSockets with GetLastItemFragmentHTML.

engine.BroadcastFragment(feed.GetLastItemFragmentHTML());The members you reach for most often.
AddActivity(aActor, aAction, aTarget, aColor, aIcon, aActorAvatarURL) appends one entry and returns the TsgcHTMLActivityItem.
MaxItems caps how many entries are kept; the oldest item is dropped automatically once the limit is reached.
ShowRelativeTime renders "3 min ago"-style timestamps kept live client-side; TimeFormat is the fallback when it's off.
GetItemFragmentHTML / GetLastItemFragmentHTML build an out-of-band htmx fragment for PushFragment / BroadcastFragment, so a new activity appears without a reload.
EmptyText is the placeholder shown while Items is empty; GetEmptyFragmentHTML re-renders it as a push fragment.
Title labels the feed, Compact tightens row spacing, and HTML returns the feed plus its scoped CSS and script.
