Gate

Descripción

Gates control when the dispatcher processes events.

Here is an example of using a gate:

public class MyElement : VisualElement
{
    void Foo()
    {
        using (new EventDispatcher.Gate(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.
