CloseGates control when the dispatcher processes events.
Here is an example of using a gate:
public class MyElement : VisualElement { void Foo() { using (new EventDispatcherGate(dispatcher)) { // do something that sends events } } }
When the gate is instantiated, it closes automatically, causing the dispatcher to store the events it receives in a queue. At the end of the using
block, Dispose is called, which triggers opening the gate. When all gates on a dispatcher open, the events stored in the queue are processed. Closing a gate while the event queue is processed does not stop it from being processed. Instead, a new queue is created to store new events.
EventDispatcherGate | Constructor. |
Dispose | Implementation of IDisposable.Dispose. Opens the gate. If all gates are open, events in the queue are processed. |
