wpf - 在 Windows 应用商店应用程序（Windows 8 Metro）中创建图标的最佳方式？

Question

我只是了解在 Visual Studio 2012 的 Windows Store App 中创建后退按钮，微软使用这个值/键对

<x:String x:Key="BackButtonGlyph">&#xE071;</x:String>

是 Unicode 吗？如果是，如何获取 Windows 应用商店应用程序的有效代码列表，因为我使用了其中一些代码，它显示了一个空矩形？

Answer 1

基于这篇文章我创建了一个样式。

首先，在 StandardStyle.xaml（文件顶部）中添加字符串字典项

<ResourceDictionary.ThemeDictionaries>
         <ResourceDictionary x:Key="Default">
         <x:String x:Key="DeleteButtonGlyph">&#xE107;</x:String>
   </ResourceDictionary>
   .

然后，在另一个或相同的 xaml 文件（样式文件）中添加以下样式

 <Style x:Key="DeleteButtonStyle" TargetType="Button">
    <Setter Property="MinWidth" Value="0"/>
    <Setter Property="ToolTipService.ToolTip" Value="Delete Selected Word"></Setter>
    <Setter Property="Margin" Value="5"/>
    <Setter Property="VerticalAlignment" Value="Bottom"/>
    <Setter Property="FontFamily" Value="Segoe UI Symbol"/>
    <Setter Property="FontWeight" Value="Normal"/>
    <Setter Property="FontSize" Value="24"/>
    <Setter Property="AutomationProperties.AutomationId" Value="DeleteButton"/>
    <Setter Property="AutomationProperties.Name" Value="Delete"/>
    <Setter Property="AutomationProperties.ItemType" Value="Delete Button"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid x:Name="RootGrid" Width="80">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition/>
                        </Grid.ColumnDefinitions>
                        <Grid.RowDefinitions>
                            <RowDefinition/>
                            <RowDefinition/>
                        </Grid.RowDefinitions>
                        <TextBlock Text="&#xE0DD;" FontSize="32" Margin="15, 0,0,0"></TextBlock>
                        <TextBlock x:Name="BackgroundGlyph" FontSize="32" Margin="15,0,0,0" Text="&#xE0DE;" Foreground="{StaticResource BackButtonBackgroundThemeBrush}"/>
                        <TextBlock Grid.Column="0" Grid.Row="0" Margin="25, 9,0,0"  x:Name="NormalGlyph" Text="{StaticResource DeleteButtonGlyph}" Foreground="{StaticResource BackButtonForegroundThemeBrush}"/>
                        <TextBlock Grid.Column="0" Grid.Row="0" Margin="25, 9,0,0" x:Name="ArrowGlyph" Text="{StaticResource DeleteButtonGlyph}" Foreground="{StaticResource BackButtonPressedForegroundThemeBrush}" Opacity="0"/>
                        <TextBlock Margin="0,10,0,5" Grid.Row="1" FontSize="12" Text="Delete Word" VerticalAlignment="Center" HorizontalAlignment="Center"></TextBlock>
                    </Grid>

                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal" />

关于获取有效代码列表，如果您有 Windows 8 设备可以运行它，我强烈推荐此应用程序。它提供了大量现有 Windows 8 Dev 图标及其匹配代码的列表。它还让您更好地了解它们在 Metro 环境中的显示方式，并且该应用程序还提供了 XAML 示例，用于在各种结构中呈现图标，包括按钮、文本框或 AppBar。

正如您在上面的链接中看到的那样，您已经将 Metro Icons 作为字体，但我建议使用我提供的应用程序作为参考，以便轻松找到每个图标的代码。
