UiEvent

class Core/Vixen.Ui/UiEvent.cs:46
csharp
public abstract class UiEvent

Anything routed through the element tree.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

Capture down, target, bubble back out — the DOM's model, and it is the right one for the same reason: an ancestor sometimes needs to see an event before its children (a scroll view swallowing a drag) and usually needs to see it after (a button inside a list row that also wants the click). One direction can express neither case without the handler knowing about the other.

Handled stops the walk for everyone except handlers that asked for handled events too. That exception exists because "did anyone deal with this" is a legitimate question — a focus manager or a diagnostic overlay needs to hear about the click that a button already consumed.
