NotifyEvents Property

Selects how threaded server events are synchronized with the main VCL/FMX thread.

Syntax

property NotifyEvents: TwsNotifyEvent read GetNotifyEvents write SetNotifyEvents;

—

Defines the threading model used to dispatch all server events (OnSTUN* and OnTURN*):

neAsynchronous (default): events are queued and delivered to the main thread asynchronously; the listener thread keeps processing new datagrams.
neSynchronous: events are delivered via TThread.Synchronize; the listener thread is blocked until the handler returns, which is safer for UI code but reduces throughput — not recommended for busy TURN servers because it serializes every relayed packet against the UI.
neNoSync: events fire directly on the listener thread. Recommended for the relay hot-path (OnTURNBeforeRelayIndication, OnTURNBeforeRelayChannelData) when the server runs headless; you must serialize any shared state yourself and avoid touching non-thread-safe UI controls.

oTURN.NotifyEvents := neAsynchronous;
oTURN.Active := True;
