adorner를 사용하여 모든면에서 창 크기 조정을 구현하는 방법은 무엇입니까?

Question

나는 모든면에서 크기를 조정할 수있는 경계없는 투명 wpf 창 (WindowStyle = None)이 있습니다. ResizeMode = CanResizeWithGrip을 설정하면 현재 크기 조정은 위의 설정으로 만 작동합니다. 이것은 시각적 큐에 좋지만 한 구석에서 크기를 조정할 수 있기 때문에 좋지 않습니다.

저는 adorner와 함께이 작업을하고 싶습니다. 따라서 윈도우가 크기 조절 모드 (켜기/끄기 가능) 일 때 시각적 큐를 줄 수도 있습니다. 이것이 가능한가? 그렇다면 어떻게해야할까요?

이 질문에 대한 답변이 이미 stackoverflow 어딘지 알려졌습니다. 나는 그것을 지금 실제로 발견 할 수 없다. 그러나 내가 그것을 어떻게 여기에서했는지에 관해 여기에서있다.
