WPF Metro UI - LinkGroup 水平滚动问题

WPF Metro UI - LinkGroup horizontal scrolling issue

我有带 Metro 的 WPF 应用 UI。 Main window 全屏打开。最重要的是,我有 MenuLinkGroup,它看起来像这样:

 <mui:ModernWindow.MenuLinkGroups>
        <mui:LinkGroup DisplayName="FirstGroup">
            <mui:LinkGroup.Links>
                <mui:Link DisplayName="Very long description" Source=""/>
                <mui:Link DisplayName="Very long description" Source=""/>
            </mui:LinkGroup.Links>
        </mui:LinkGroup>
        <mui:LinkGroup DisplayName="SecondGroup">
            <mui:LinkGroup.Links>
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
            </mui:LinkGroup.Links>
        </mui:LinkGroup>
        <mui:LinkGroup DisplayName="ThirdGroup">
            <mui:LinkGroup.Links>
                <mui:Link DisplayName="Very long description" Source="" />
                <mui:Link DisplayName="Very long description" Source="" />
            </mui:LinkGroup.Links>
        </mui:LinkGroup>
</mui:ModernWindow.MenuLinkGroups>

主要问题是,当用户的显示器较小时,他无法看到 SecondGroup 中的所有名称,并且他无法使用鼠标光标轻松导航 tchem。

我的问题:屏幕太小的时候,有没有可以放一些卷轴或者包裹的东西?

要修复 FirstFloor.ModernUI 中的菜单布局,您需要为 ModernMenu 控件编写新的 wpf 样式以覆盖默认布局。默认样式代码可以在项目 github 页面 https://github.com/firstfloorsoftware/mui/blob/master/1.0/FirstFloor.ModernUI/Shared/Themes/ModernMenu.xaml 上找到。在您的应用程序中,例如在 App.xaml 中添加对 ModernMenu class 命名空间的引用:

xmlns:firstfloor="clr-namespace:FirstFloor.ModernUI.Windows.Controls;assembly=FirstFloor.ModernUI"

然后在资源中定义新的默认样式:

<Style TargetType="firstfloor:ModernMenu"></Style>

改成wrapped menu的关键点是把2个列表框ItemsPanel从StackPanel改成WrapPanel,然后设置属性 ScrollViewer.HorizontalScrollBarVisibility="Disabled"。完成这些更改后,您的样式应如下所示:

<Style TargetType="firstfloor:ModernMenu">
    <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="firstfloor:ModernMenu">
                <Grid>
                    <Grid.Resources>
                        <Style TargetType="ListBox" BasedOn="{StaticResource {x:Type ListBox}}">
                            <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Hidden"/>
                            <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Hidden"/>
                            <Setter Property="ScrollViewer.CanContentScroll" Value="false"/>
                            <Setter Property="ScrollViewer.PanningMode" Value="Both"/>
                        </Style>
                    </Grid.Resources>

                    <Grid.RowDefinitions>
                        <RowDefinition />
                        <RowDefinition />
                    </Grid.RowDefinitions>

                    <ListBox ItemsSource="{TemplateBinding VisibleLinkGroups}"
                             ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                             SelectedItem="{Binding SelectedLinkGroup, RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}">
                        <ListBox.ItemContainerStyle>
                            <Style TargetType="ListBoxItem">
                                <Setter Property="FocusVisualStyle" Value="{x:Null}" />
                                <Setter Property="FontFamily" Value="Segoe UI Light" />
                                <Setter Property="Foreground" Value="{DynamicResource MenuText}" />
                                <Setter Property="FontSize" Value="23"/>
                                <Setter Property="HorizontalContentAlignment" Value="Center" />
