WPF 将选项卡项样式设置为箭头状
WPF styling tab items as arrow-like
我想设置我的 TabControl 的样式使其具有与此类似的项目:
我尝试将边界(右侧厚度为 0)和三角形多边形组合在一起,将多边形推到边界外一点以重叠,但它并没有真正起作用,因为多边形的边界外部分被隐藏了.这是我的尝试,现在我被困住了,真的不知道还能尝试什么:
<!-- Styles -->
<Style TargetType="{x:Type TabItem}">
<Setter Property="Padding" Value="15 0 15 0" />
<Setter Property="Background" Value="#f5f5f5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid ClipToBounds="False">
<Border x:Name="PART_Border"
Padding="{TemplateBinding Padding}"
Background="{TemplateBinding Background}"
BorderThickness="1 1 0 1"
BorderBrush="LightGray">
<ContentPresenter ContentSource="Header" VerticalAlignment="Center" />
</Border>
<Polygon Points="0,0 20,25, 0,50"
Stroke="#e8e8e8"
Fill="#ffffff"
HorizontalAlignment="Right"
Margin="0 0 -10 0"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="PART_Border" Property="Background" Value="#ffffff" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- Content -->
<TabControl>
<TabItem Header="First" />
<TabItem Header="Second" />
<TabItem Header="Third" />
</TabControl>
这将为您完成工作:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Background" Value="#f5f5f5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Path x:Name="Back" Data="M0,0 L 80,0 L100,20 L80,40 L0,40 L 20,20 " Stretch="None" VerticalAlignment="Stretch"
Stroke="#e8e8e8" StrokeThickness="2"
Fill="{TemplateBinding Background}"
HorizontalAlignment="Stretch" Margin="-30,0,0,0"/>
<ContentPresenter ContentSource="Header" VerticalAlignment="Center" />
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Back" Property="Fill" Value="#ffffff" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我没有使用边框和多边形来为您绘制形状。
您可以在边距中使用 -(负)值来重叠项目。
结果:
