ActivityFeed

Family: Data & Inspection
Namespace: Tessera.Controls

Use ActivityFeed when this interaction is the best match for your screen workflow.

When to use

• You need a ActivityFeed-style interaction inside the data & inspection lane.
• A titled widget surface improves scanability in dense shells.
• You want explicit user-driven events routed into app state updates.

Minimal usage

csharp.cs

using Tessera.Controls;
using Tessera.Layout;

var widget = new ActivityFeed
{
    Title = "ActivityFeed"
};

return Screen.Build(window => window.Body(body => body.Center(widget, width: 44, height: 9)));

Common pitfalls

• Do not choose ActivityFeed by name only; validate it against the target workflow.
• Keep this control scoped to the data & inspection concern; avoid cross-layer state coupling.
• Handle control events by posting/processing messages; avoid hidden mutation in render paths.
• Set focused/normal styles intentionally so keyboard focus remains obvious.
• Keep disabled state explicit and reversible so users understand why actions are blocked.
