UWP 为枢轴创建边框 Header
UWP Create border for Pivot Header
我正在使用 pivot 创建一个包含 3 个选项的菜单。代码如下。
<Pivot x:Name="menuPivot" Margin="0" SelectedIndex="0" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Row="1" Grid.ColumnSpan="2" SelectionChanged="ListView_SelectionChanged">
<PivotItem Header="Day" VerticalAlignment="Center" HorizontalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Margin="0,0,10,0" />
<PivotItem Header="Week" VerticalAlignment="Center" HorizontalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Margin="0,0,10,0" />
<PivotItem Header="Month" VerticalAlignment="Center" HorizontalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Margin="-1,0,0,0" Background="#FFFB0000" BorderBrush="{StaticResource currentThemeColor}" />
</Pivot>
我需要实现菜单的外观：
到目前为止，我已经使用以下代码更改了 Header 的 Pivots 默认样式：
<Style TargetType="PivotHeaderItem">
<Setter Property="FontSize" Value="{ThemeResource PivotHeaderItemFontSize}" />
<Setter Property="FontFamily" Value="{ThemeResource PivotHeaderItemFontFamily}" />
<Setter Property="FontWeight" Value="{ThemeResource PivotHeaderItemThemeFontWeight}" />
<Setter Property="CharacterSpacing" Value="{ThemeResource PivotHeaderItemCharacterSpacing}" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="Gray" />
<!-- original value {ThemeResource SystemControlForegroundBaseMediumBrush} -->
<Setter Property="Padding" Value="{ThemeResource PivotHeaderItemMargin}" />
<Setter Property="Height" Value="48" />

我是这样看的：
我不知道如何像第一张图片那样添加边框，以及如何更改所选的边框颜色header？
此外，如果您认为使用 Pivot 以外的其他控件可以更轻松地完成此操作，那也会有所帮助。
您可以在顶部使用 RadioButtons 的 3（或者 5，如果您将分隔符放在它们自己的列中）列网格来展开您自己的控件，以显示 headers。看着 default template 它似乎是一个非常黑的盒子，你最好自己做。您也可以只从默认的 headers 中删除，并在重新设计的 Pivot.
上方有一个 3 列网格
您可以像这样在 PivotHeaderItem 模板中添加四个 Border：
<Style TargetType="PivotHeaderItem">

<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="PivotHeaderItem">
<Grid x:Name="Grid" Background="{TemplateBinding Background}" Width="100">

VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
<ContentPresenter.RenderTransform>
<TranslateTransform x:Name="ContentPresenterTranslateTransform" />
</ContentPresenter.RenderTransform>
</ContentPresenter>
<Border x:Name="TopLine" Height="3" Background="Blue" VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<Border x:Name="BottomLine" Height="2" Background="LightGray" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" />
<Border x:Name="RightLine" Width="1" Background="LightGray" VerticalAlignment="Center"
HorizontalAlignment="Right" Height="{TemplateBinding FontSize}" />
<Border x:Name="SelectedLine" Height="2" VerticalAlignment="Bottom" HorizontalAlignment="Stretch"
Background="LightGray" Margin="15,0,0,0" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我在样式中注释了部分代码，以便清楚地显示我修改的内容，你可以看到我给Grid设置了一个宽度来测试这里，你可以去掉它。
我还修改了 Selected 视觉状态，以更改页眉的前景、"Separator" 的宽度和我的 SelectedLine 的背景。下面是我的风格渲染图：
