如何在WPF中重新设置TabControl

Question

我是WPF的新手。在这里，我发布了TabControl的图片。只需指导我如何根据我的图片重新设置WPF中具有相同UI的选项卡。

Answer 1

在这种情况下，您需要为Style实施Template / TabControl才能获得此表单。 TabControl标签有三个方向：中央（ default ），左右方向。你需要离开方向，从图片来判断。

TabItem的样式（TabControl的元素）将是所有方向的样式。

TabControl的样式，左方向：

<Style x:Key="LeftTabControl" TargetType="{x:Type TabControl}">
        <Setter Property="TabStripPlacement" Value="Left" />
        <Setter Property="Margin" Value="0" />
        <Setter Property="Padding" Value="0" />
        <Setter Property="Background" Value="White" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="BorderBrush" Value="Transparent" />

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TabControl}">
                    <Grid ClipToBounds="True" SnapsToDevicePixels="True" KeyboardNavigation.TabNavigation="Local">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Name="ColumnDefinition0" />
                            <ColumnDefinition Width="0" Name="ColumnDefinition1" />
                        </Grid.ColumnDefinitions>

                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto" Name="RowDefinition0" />
                            <RowDefinition Height="*" Name="RowDefinition1" />
                        </Grid.RowDefinitions>

                        <Border x:Name="HeaderBorder" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0" Background="#FAFAFA" Margin="0">
                            <TabPanel IsItemsHost="True" Name="HeaderPanel" Panel.ZIndex="1" KeyboardNavigation.TabIndex="1" Grid.Column="0" Grid.Row="0" />
                        </Border>

                        <Grid Name="ContentPanel" KeyboardNavigation.TabIndex="2" KeyboardNavigation.TabNavigation="Local" KeyboardNavigation.DirectionalNavigation="Contained" Grid.Column="0" Grid.Row="1">
                            <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0">
                                <ContentPresenter Content="{TemplateBinding SelectedContent}" ContentTemplate="{TemplateBinding SelectedContentTemplate}" ContentStringFormat="{TemplateBinding SelectedContentStringFormat}" ContentSource="SelectedContent" Name="PART_SelectedContentHost" Margin="2" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" />
                            </Border>
                        </Grid>
                    </Grid>

                    <ControlTemplate.Triggers>
                        <Trigger Property="TabControl.TabStripPlacement" Value="Left">
                            <Setter TargetName="HeaderPanel" Property="Grid.Row" Value="0" />
                            <Setter TargetName="ContentPanel" Property="Grid.Row" Value="0" />

                            <Setter TargetName="ColumnDefinition1" Property="ColumnDefinition.Width" Value="*" />
                            <Setter TargetName="RowDefinition0" Property="RowDefinition.Height" Value="*" />
                            <Setter TargetName="RowDefinition1" Property="RowDefinition.Height" Value="0" />
                            <Setter TargetName="HeaderBorder" Property="FrameworkElement.Margin" Value="0,0,0,0" />
                        </Trigger>

                </ControlTemplate>
            </Setter.Value>
        </Setter>

TabItem的样式：

MainWindow

<TabControl Style="{StaticResource LeftTabControl}" Background="Gainsboro" Width="300" HorizontalAlignment="Left">
    <TabItem Header="New">
        <Label Content="TestNew" />
    </TabItem>

    <TabItem Header="Old">
        <Label Content="TestOld" />
    </TabItem>

    <TabItem Header="Recent">
        <Label Content="RecentHelp" />
    </TabItem>
</TabControl>

Output

要添加三角形选择，您需要修复TabItem的模板。添加带有三角形的Path并将其显示在当前TabItem：

中

<ControlTemplate TargetType="{x:Type TabItem}">
    <Border SnapsToDevicePixels="True" Name="Border" Margin="0,0,2,0" Padding="2" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0">
        <Grid>
            <Path x:Name="CurrentTriangle" Width="10" Height="14" Stretch="Fill" Margin="0,0,-3,0" Fill="#FAFAFA" HorizontalAlignment="Right" Data="F1 M 287.328,237.333L 319.344,255.818L 319.344,218.849L 287.328,237.333 Z " Visibility="Collapsed" />
            <ContentPresenter Name="ContentSite" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="5,5,5,5" VerticalAlignment="Center" RecognizesAccessKey="True" ContentSource="Header" />
        </Grid>
    </Border>

    <ControlTemplate.Triggers>
        ...

        <Trigger Property="IsSelected" Value="True">
            <Setter TargetName="CurrentTriangle" Property="Visibility" Value="Visible" />
        </Trigger>
    </ControlTemplate.Triggers>
</ControlTemplate>

三角形输出：

            </Trigger>
        </Style.Triggers>
</Style>

Edit:我会按顺序告诉你。

我上面给出的所有Styles都放在App.xaml那样的（最好是他们在那里）：

<Application x:Class="SomeProgram.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:PresentationOptions="http://schemas.microsoft.com/winfx/2006/xaml/presentation/options" 
         StartupUri="MainWindow.xaml">

<Application.Resources>
    <Style x:Key="LeftTabControl" TargetType="{x:Type TabControl}">
     ...
    </Style>

<Style x:Key="{x:Type TabItem}" TargetType="{x:Type TabItem}">
     ...
    </Style>
</Application.Resources>

  

指定Triangle的图片路径。

默认情况下，TabItem的模板如下所示：

<Setter Property="Template">
    <Setter.Value>
        <Border SnapsToDevicePixels="True" Name="Border" Margin="0,0,2,0" Padding="2" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0">
            <ContentPresenter Name="ContentSite" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="5,5,5,5" VerticalAlignment="Center" RecognizesAccessKey="True" ContentSource="Header" />
        </Border>

负责显示内容的ContentPresenter，在这种情况下用于显示标题中的文本。但是我们需要显示一个三角形，所以将他添加为数字Path：

<Path x:Name="CurrentTriangle" Width="10" Height="14" Stretch="Fill" Margin="0,0,-3,0" Fill="#FAFAFA" HorizontalAlignment="Right" Data="F1 M 287.328,237.333L 319.344,255.818L 319.344,218.849L 287.328,237.333 Z " Visibility="Collapsed" />

这不是Image，Path更容易使用，无需保留资源。您可以找到更多信息here。

所以，现在我们出现了一个三角形，但是我们需要在选择标签时显示它。为此，我们使用触发器来执行此操作：

<Trigger Property="IsSelected" Value="True">
    <Setter TargetName="CurrentTriangle" Property="Visibility" Value="Visible" />
</Trigger>

有关您可以找到here的触发器的更多信息。

  

所选TabItem的渐变背景色。

所选TabItem的颜色也设置为TabItem样式的触发器：

<Trigger Property="IsSelected" Value="True">
    <Setter Property="Background" Value="#F5B79C" />
    <Setter Property="Foreground" Value="Black" />
</Trigger>

此处设置所选Background的{​​{1}}和Foreground的值。渐变颜色定义如下：

TabItem

您需要在触发器中为属性<LinearGradientBrush> <GradientStop Color="Yellow" Offset="0.0" /> <GradientStop Color="Orange" Offset="0.5" /> <GradientStop Color="Red" Offset="1.0" /> </LinearGradientBrush> 设置渐变颜色。

  

TabControl的背景

此行的Background样式设置为

Background：

TabControl's

Answer 2

试试这个。 在窗口上添加选项卡控件，然后将TabStripPlacement设置为Left。然后向此选项卡控件添加一些选项卡项。现在在Windows.Resource部分添加Style。
