wpf - 在 WPF TabControl 上 - 我可以在选项卡标题旁边添加内容吗？

Question

有没有一种简单的方法可以将另一个控件(即按钮)内联定位到 WPF 中选项卡标题的右侧？

在网络中，我会使用 float 或绝对定位来实现这一点。

这张图片中的红线是我想要达到的:

做到这一点的可靠方法是重新模板化 TabControl就像我对 ActiveAwareCommand sample 中的关闭按钮所做的那样:

<ControlTemplate x:Key="TabControlTemplate" TargetType="TabControl">
    <Grid ClipToBounds="true" SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local">
        <Grid.ColumnDefinitions>
            <ColumnDefinition x:Name="ColumnDefinition0"/>
            <ColumnDefinition x:Name="ColumnDefinition1" Width="0"/>
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition x:Name="RowDefinition0" Height="Auto"/>
            <RowDefinition x:Name="RowDefinition1" Height="*"/>
        </Grid.RowDefinitions>
        <Grid Panel.ZIndex="1">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TabPanel Margin="2,2,2,0" x:Name="HeaderPanel" IsItemsHost="true" KeyboardNavigation.TabIndex="1"/>
            <Button Grid.Column="1" Command="{Binding DataContext.CloseCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">X</Button>
        </Grid>
        <Border x:Name="ContentPanel" Grid.Column="0" Grid.Row="1" BorderBrush="#D0CEBF" BorderThickness="0,0,1,1" KeyboardNavigation.DirectionalNavigation="Contained" KeyboardNavigation.TabIndex="2" KeyboardNavigation.TabNavigation="Local">
            <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                <Border Background="{TemplateBinding Background}">
                    <Grid x:Name="PART_ItemsHolder"/>
                </Border>
            </Border>
        </Border>
    </Grid>
</ControlTemplate>

注意 TabPanel和 Button永远不能重叠。结果:
