커스텀 이벤트를 합성하고 전송하기 전에 UIElement가 운영체제 이벤트를 할당하고 전송하는 방식을 이해해야 합니다.
UIElements는 이벤트 풀을 사용하여 이벤트 오브젝트의 반복 할당을 방지합니다. 고유한 이벤트를 합성하고 전송하려면 다음의 동일한 단계에 따라 이벤트를 할당하고 전송해야 합니다.
using
블록으로 둘러싸서 이벤트 풀에 반환되도록 만듭니다.element.SendEvent()
로 전달합니다.일반적으로 운영체제에서 오는 이벤트(예: 키보드 이벤트, 일부 마우스 이벤트 등)를 전송하려면 UnityEngine.Event
를 사용하여 UIElements 이벤트를 초기화하십시오.
다음 예제는 이벤트를 합성하고 전송하는 방식을 보여줍니다.
void SynthesizeAndSendKeyDownEvent(IPanel panel, KeyCode code,
char character = '\0', EventModifiers modifiers = EventModifiers.None)
{
// Create a UnityEngine.Event to hold initialization data.
// Also, this event will be forwarded to IMGUIContainer.m_OnGUIHandler
var evt = new Event() {
type = EventType.KeyDownEvent,
keyCode = code,
character = character,
modifiers = modifiers
};
using (KeyDownEvent keyDownEvent = KeyDownEvent.GetPooled(evt))
{
UIElementsUtility.eventDispatcher.DispatchEvent(keyDownEvent, panel);
}
}
