[wpf] WPF 탭 컨트롤에서 사다리꼴 탭을 만드는 방법

인터넷에서이 문제에 대한 컨트롤 템플릿이나 솔루션을 찾으려고했지만 “용인 할 수있는”솔루션을 찾지 못했습니다. 그래서 나는 그것을 내 방식으로 썼고 여기에 나의 첫 번째 (그리고 마지막 =)) 시도의 예가 있습니다.

이 두 변환기는 탭 크기를 내용에 맞게 조정했습니다. 사실 콘텐츠 크기에 따라 Path 객체를 만듭니다. 다양한 너비의 탭이 필요하지 않은 경우 다음과 같이 수정 된 사본을 사용할 수 있습니다.

<Style x:Key="tabPath" TargetType="{x:Type Path}">
      <Setter Property="Stroke" Value="Black"/>
      <Setter Property="Data">
          <Setter.Value>
              <PathGeometry Figures="M 0,0 L 0,14 C 0,18 2,20 6,20 L 60,20 C 70,20 80,0 84,0"/>
          </Setter.Value>
      </Setter>
  </Style>
