WPF 탭 컨트롤에서 사다리꼴 탭을 만드는 방법
WPF 탭 컨트롤에서 사다리꼴 탭을 만드는 방법은 무엇입니까?
Google 크롬의 탭이나 VS 2008 코드 편집기의 탭처럼 보이는 직사각형이 아닌 탭을 만들고 싶습니다.
WPF 스타일로 수행 할 수 있습니까? 아니면 코드로 그려야합니까?
인터넷에서 사용할 수있는 코드의 예가 있습니까?
편집하다:
모서리를 둥글게하거나 탭의 색상을 변경하는 방법을 보여주는 많은 예제가 있지만 다음 두 예제와 같이 탭의 지오메트리를 변경하는 예제를 찾을 수 없습니다.
VS 2008 코드 편집기 탭
Google 크롬 탭
이 두 예의 탭은 직사각형이 아니라 사다리꼴입니다.
인터넷에서이 문제에 대한 컨트롤 템플릿이나 솔루션을 찾으려고했지만 "용인 할 수있는"솔루션을 찾지 못했습니다. 그래서 나는 그것을 내 방식으로 썼고 여기에 첫 번째 (그리고 마지막 =)) 시도의 예가 있습니다.

이 두 변환기는 탭 크기를 내용에 맞게 조정하기 위해 작성했습니다. 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">

참고 : 이것은 Rooks의 훌륭한 답변에 대한 부록 일뿐입니다.
Rooks의 솔루션이 런타임에 완벽하게 작동하는 동안 VS2010 WPF 디자이너 화면에서 MainWindow를 열 때 몇 가지 문제가 발생했습니다. 디자이너가 예외를 던지고 창을 표시하지 않았습니다. 또한 TabControl.xaml의 TabItem에 대한 전체 ControlTemplate에는 파란색 물결 선이 있었고 도구 설명은 NullReferenceException이 발생했음을 알려주었습니다. 관련 코드를 내 응용 프로그램으로 옮길 때 동일한 동작이 발생했습니다. 문제는 두 개의 다른 컴퓨터에 있었기 때문에 설치 문제와 관련이 없다고 생각합니다.
누군가가 동일한 문제를 경험하는 경우 예제가 런타임 및 디자이너에서도 작동하도록 수정을 찾았습니다.
첫째 : TabControl-XAML 코드에서 교체 ...
<Path x:Name="TabPath" StrokeThickness="2"
Margin="{Binding ElementName=TabItemContent,
Converter={StaticResource content2MarginConverter}}"
Stroke="{StaticResource BorderBrush}"
Fill="{StaticResource TabItemPathBrush}">
<Path.Data>
<PathGeometry>
<PathFigure IsClosed="False" StartPoint="1,0"
Segments="{Binding ElementName=TabItemContent,
Converter={StaticResource content2PathConverter}}">
</PathFigure>
</PathGeometry>
</Path.Data>
<Path.LayoutTransform>
<ScaleTransform ScaleY="-1"/>
</Path.LayoutTransform>
</Path>
... 작성자 : ...
<Path x:Name="TabPath" StrokeThickness="2"
Margin="{Binding ElementName=TabItemContent,
Converter={StaticResource content2MarginConverter}}"
Stroke="{StaticResource BorderBrush}"
Fill="{StaticResource TabItemPathBrush}"
Data="{Binding ElementName=TabItemContent,
Converter={StaticResource content2PathConverter}}">
<Path.LayoutTransform>
<ScaleTransform ScaleY="-1"/>
</Path.LayoutTransform>
</Path>
두 번째 : ContentToPathConverter 클래스의 Convert 메서드 끝에서 바꾸기 ...
return ps;
... 작성자 : ...
PathFigure figure = new PathFigure(new Point(1, 0), ps, false);
PathGeometry geometry = new PathGeometry();
geometry.Figures.Add(figure);
return geometry;
왜 이것이 디자이너에서 안정적으로 실행되는지에 대한 설명이 없지만 rooks의 원래 코드는 아닙니다.
방금 WPF 용 Google Chrome과 유사한 탭 컨트롤을 완료했습니다. https://github.com/realistschuckle/wpfchrometabs 에서 프로젝트를 찾을 수 있으며 이를 설명하는 블로그 게시물은
사용자 지정 탭 컨트롤을 처음부터 빌드하는 방법을 더 잘 이해하는 데 도움이되기를 바랍니다.

나는 이것이 오래되었다는 것을 알고 있지만 제안하고 싶습니다.

<Setter TargetName="Polygon_Part" Property="Stroke" Value="LightGray"/>
<Setter TargetName="Polygon_Part" Property="Fill" Value="DimGray" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Polygon_Part" Property="Fill" Value="Goldenrod" />
<Setter TargetName="Polygon_Part" Property="Stroke" Value="LightGray"/>

yep, you can do that--basically all you have to do is make a custom control-template. Check out http://www.switchonthecode.com/tutorials/the-wpf-tab-control-inside-and-out for a tutorial. Just googling "wpf" "tabcontrol" "shape" turns up pages of results.
I have not tried this myself, but you should be able to replace the tag(s) in the template with tags to get the shape that you want.
To slope both left and right tab edges, here is a modification of Slauma's enhancement to rook's accepted answer. This is a replacement of Convert method of the ContentToPathConverter class:
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
var ps = new PathSegmentCollection(4);
ContentPresenter cp = (ContentPresenter)value;
double h = cp.ActualHeight > 10 ? 1.4 * cp.ActualHeight : 10;
double w = cp.ActualWidth > 10 ? 1.25 * cp.ActualWidth : 10;
// Smaller unit, so don't need fractional multipliers.
double u = 0.1 * h;
// HACK: Start before "normal" start of tab.
double x0 = -4 * u;
// end of transition
double x9 = w + 8 * u;
// transition width
double tw = 8 * u;
// top "radius" (actually, gradualness of curve. Larger value is more rounded.)
double rt = 5 * u;
// bottom "radius" (actually, gradualness of curve. Larger value is more rounded.)
double rb = 3 * u;
// "(x0, 0)" is start point - defined in PathFigure.
// Cubic: From previous endpoint, 2 control points + new endpoint.
ps.Add(new BezierSegment(new Point(x0 + rb, 0), new Point(x0 + tw - rt, h), new Point(x0 + tw, h), true));
ps.Add(new LineSegment(new Point(x9 - tw, h), true));
ps.Add(new BezierSegment(new Point(x9 - tw + rt, h), new Point(x9 - rb, 0), new Point(x9, 0), true));
// "(x0, 0)" is start point.
PathFigure figure = new PathFigure(new Point(x0, 0), ps, false);
PathGeometry geometry = new PathGeometry();
geometry.Figures.Add(figure);
return geometry;
}
또한 TabControl의 ControlTemplate에서 탭 항목의 컨테이너에 왼쪽 (및 선택적으로 오른쪽) 여백을 추가합니다 (변경 사항 만 추가됨 Margin="20,0,20,0").
<Style x:Key="TabControlStyle" TargetType="{x:Type TabControl}">
...
<Setter Property="Template">
...
<StackPanel Grid.Row="0" Panel.ZIndex="1" Orientation="Horizontal" IsItemsHost="true" Margin="20,0,20,0"/>
문제 : 선택한 탭이 아닌 경우 탭의 왼쪽 가장자리 하단에 약간의 시각적 "글리치"가 있습니다. 탭 영역이 시작되기 전에 시작하는 것이 "뒤로 가기"와 관련이 있다고 생각합니다. 또는 탭 하단의 선 그리기와 관련이 있습니다 (탭 "일반"직사각형의 왼쪽 가장자리 이전에 시작한다는 것을 알지 못함).
