如何在 Tab Control 对象中禁用 Tab 环绕 [英] How to disable tab wrapping in the Tab Control object

问题描述

我正在 WPF/C# 中设计一个 GUI，我正在使用 Tab Control 对象.我的 tab 控件 将包含很多选项卡，我想知道如何禁用对象的默认包装"行为.基本上与这个问题相反.我该怎么做?

I'm designing a GUI in WPF/C# and I'm using the Tab Control object. My tab control will contain a lot of tabs, and I would like to know how to disable the default "wrapping" behavior of the object. Basically the opposite of this question. How would I go about doing that?

谢谢.

推荐答案

只需更改ItemsPanel:

<TabControl ....>
   <TabControl.ItemsPanel>
     <ItemsPanelTemplate>
        <StackPanel Orientation="Horizontal"/>
     </ItemsPanelTemplate>
   </TabControl.ItemsPanel>
  ....
</TabControl>

刚刚测试过，没有用.@SimonBelanger 是对的.

Just tested and it doesn't work. @SimonBelanger is right.

这是<代码的默认模板的副本>TabControl，稍作修改，将 TabPanel 更改为 Horizo​​ntal StackPanel:

Here is a copy of the Default Template of the TabControl, with a slight modification that changes the TabPanel to a Horizontal StackPanel:

<TabControl>
        <TabControl.Template>
            <ControlTemplate TargetType="{x:Type 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>
                    <StackPanel x:Name="HeaderPanel" Grid.Column="0" IsItemsHost="true" Margin="2,2,2,0" Grid.Row="0" KeyboardNavigation.TabIndex="1" Panel.ZIndex="1" Orientation="Horizontal"/>
                    <Border x:Name="ContentPanel" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Column="0" KeyboardNavigation.DirectionalNavigation="Contained" Grid.Row="1" KeyboardNavigation.TabIndex="2" KeyboardNavigation.TabNavigation="Local">

                    </Border>
                </Grid>
