重新想象 Windows 8.1 Store Apps (75) - 新增控件: Hub, Hyperlink

作者：webabcd


介绍
重新想象 Windows 8.1 Store Apps 之新增控件

• Hub - 中心控件（由一个 header 和多个 section 组成）
• Hyperlink - 超链接控件（在 RichEditBox, RichTextBlock, RichTextBlockOverflow 内使用）

示例
1、演示 Hub 的应用
HubDemo.xaml

<Page
    x:Name="pageRoot"
    x:Class="Windows81.Controls.HubDemo"
    DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows81.Controls"
    xmlns:common="using:Windows81.Common"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Page.Resources>
        <x:String x:Key="AppName">我的 hub</x:String>
    </Page.Resources>

    <Grid Background="Transparent">
        <Grid.ChildrenTransitions>
            <TransitionCollection>
                <EntranceThemeTransition/>
            </TransitionCollection>
        </Grid.ChildrenTransitions>

        <!--
            Hub - 中心控件（本例是通过 Hub 模板创建的）
                Header - Hub 的 Header（注：其是固定不动的）
                HubSection - Hub 的 Section
                    Header - HubSection 的 Header
                    DataTemplate - HubSection 的 DataTemplate
                    IsHeaderInteractive - 指定 HubSection 的 Header 是否是可点击的，如果是可点击的则 header 的右侧有一个“>”符号
                SectionHeaderClick - Hub 的 HubSection 的 Header 被点击后所触发的事件
                Orientation - Hub 内 Section 的排列方式（Horizontal 或 Vertical）
                DefaultSectionIndex - Hub 中被选中的 Section
        
            另：Hub 实现了 ISemanticZoomInformation 接口，关于 ISemanticZoomInformation 请参见：http://www.cnblogs.com/webabcd/archive/2013/03/21/2972537.html

HubDemo.xaml.cs

/*
 * Hub - 中心控件（由一个 header 和多个 section 组成）
 */

using System;
using Windows.UI.Popups;
using Windows.UI.Xaml.Controls;

namespace Windows81.Controls
{
    public sealed partial class HubDemo : Page
    {
        public HubDemo()
        {
            this.InitializeComponent();
        }

        // Hub 的 HubSection 的 Header 被点击后所触发的事件
        private async void Hub_SectionHeaderClick(object sender, HubSectionHeaderClickEventArgs e)
        {
            switch (e.Section.Name)
            {
                case "s2":
                    await new MessageDialog("点击了 Section 2", "提示").ShowAsync();
                    break;
                case "s3":
                    await new MessageDialog("点击了 Section 3", "提示").ShowAsync();
                    break;
                default:
                    break;
            }
        }
    }
}

2、演示 Hyperlink 的应用
HyperlinkDemo.xaml

<Page
    x:Class="Windows81.Controls.HyperlinkDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows81.Controls"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="120 0 0 0">
            
            <!--
                Hyperlink - 超链接控件（在 RichEditBox, RichTextBlock, RichTextBlockOverflow 内使用）
                    NavigateUri - 需要链接到的地址
            
                其他场景使用超链的话通过 HyperlinkButton 实现，参见：http://www.cnblogs.com/webabcd/archive/2013/01/10/2853974.html
            -->
            
            <RichTextBlock Width="200" Style="{StaticResource BasicRichTextStyle}">
                <Paragraph>
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                    <Hyperlink NavigateUri="http://webabcd.cnblogs.com" Foreground="Blue">webabcd blog</Hyperlink>
                    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
                </Paragraph>
            </RichTextBlock>
            
        </StackPanel>
    </Grid>
</Page>

HyperlinkDemo.xaml.cs

/*
 * Hyperlink - 超链接控件（在 RichEditBox, RichTextBlock, RichTextBlockOverflow 内使用）
 */

using Windows.UI.Xaml.Controls;

namespace Windows81.Controls
{
    public sealed partial class HyperlinkDemo : Page
    {
        public HyperlinkDemo()
        {
            this.InitializeComponent();
        }
    }
}
