문제

Vista와 마찬가지로 로딩 아이콘을 나타내는 XAML을 찾고 있습니다.

시각적 설명 :

  • 둥근 (너비 약 1/3 인치)
  • 가벼운 파란색
  • 투명한 센터
  • 젤 버튼 모양 (둥근 모서리 wtih 작은 그림자)
  • 가장자리 주위의 흰색 스피너, 움직임을주기 위해

라이트 (ER) 스카이 블루 / 젤 팩 외모

회전하는 사각형을 발견했으며 회전의 환상을주는 XAML을 만들 수 있지만 시계의 12 개 부분을 그리며 각각을 개별적으로 애니메이션합니다.

도움이 되었습니까?

해결책

여기 WPF로 변환 할 수있는 SL에서 만든 매우 간단한 스피너가 있습니다.

다른 팁

절대적으로 Full-XAML이어야합니까? 이런 종류의 효과의 경우 투명한 PNG가 잘 작동합니다. PNG를 그리드에 쌓고 Rotatetransform과 DoubleanImation을 사용하여 PNG를 애니메이션하십시오.

애플리케이션이 많이 확대 할 필요가 없다면 트릭을 수행하는 가장 쉬운 방법입니다.

인사, 로랑

@Joeln, 감사합니다. 이것을 WPF로 변환 할 수 있었고 필요한 것을 얻을 수있었습니다. 감사합니다.
