在列表框中更改scrollviewer模板

Question

我是WPF的新手。 我想在列表框中更改滾動查看器的模板。 我在此博客中找到了一個Apple風格的滾動條

但是我不知道如何將滾動查看器模板應用於列表框。 誰能幫我？ 這是Apple滾動查看器模板的XAML代碼：

<SolidColorBrush x:Key="ScrollBarDisabledBackground" Color="#F4F4F4"/>
        <Style x:Key="VerticalScrollBarPageButton" TargetType="{x:Type RepeatButton}">
            <Setter Property="OverridesDefaultStyle" Value="true"/>
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="Focusable" Value="false"/>
            <Setter Property="IsTabStop" Value="false"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type RepeatButton}">
                        <Rectangle Fill="{TemplateBinding Background}" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        <Style x:Key="ScrollBarThumb" TargetType="{x:Type Thumb}">
            <Setter Property="OverridesDefaultStyle" Value="true"/>

Answer 1

就像WPF中的其他幾個控件一樣， ScrollViewer也具有一些命名部分。 為了在正確的地方使用它們，需要正確命名。 在此MSDN站點上已經解釋了ScrollViewer樣式，但是基本上它包含ScrollContentPresenter ， HorizontalScrollBar和VerticalScrollBar 3部分。 反過來，每個ScrollBar將具有其自己的命名部分以進行樣式設置。 為此，請轉到此MSDN網站。 在您的情況下，您可以像這樣將ListBox包裝在ScrollViewer ：

<ScrollViewer>
   <ListBox/>
</ScrollViewer>

在這種情況下，您還可以考慮隱藏ListBox原始滾動條。 如果您對“ Listbox Height ”不加任何限制，它將增長為適合所有元素，這又將導致ScrollViewer顯示自定義滾動條。 或者，您可以像這樣更改ListBox模板（ MSDN ）：

<Style TargetType={x:Type ListBox}>
   <Setter Property="Template">
      <Setter.Value>
         <ControlTemplate TargetType="{x:Type ListBox}">  
            <ScrollViewer x:Name="ScrollViewer">  
               <ItemsPresenter/> 
            </ScrollViewer> 
         </ControlTemplate>
      </Setter.Value>
   </Setter>
</Style>

然后在那里自定義您的ScrollViewer
