我是WPF的新手。 我想在列表框中更改滚动查看器的模板。我在blog
中找到了Apple风格的滚动条但我不知道如何将该滚动查看器模板应用于列表框。谁能帮我?
以下是Apple滚动查看器模板的XAML
代码:
<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"/>
<Setter Property="IsTabStop" Value="false"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Thumb}">

ScrollViewer
具有一些命名部分。为了在正确的地方使用,需要正确命名。此MSDN网站已解释ScrollViewer
样式,但基本上它有3个部分ScrollContentPresenter
,HorizontalScrollBar
和VerticalScrollBar
。反过来,每个ScrollBar
都有自己命名的样式部分。为此,请访问此MSDN网站。在您的情况下,您可以将ListBox
包裹在ScrollViewer
中,如下所示:
<ScrollViewer>
<ListBox/>
</ScrollViewer>
在这种情况下,您可能还会考虑隐藏ListBox
的原始滚动条。如果您对Height
的{{1}}没有任何限制,它会增长到适合所有元素,这反过来会导致您的Listbox
显示自定义滚动条。
或者,您可以更改ScrollViewer
的模板,例如MSDN):
ListBox
然后自定义<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>
