WPF自定义控件 使用阿里巴巴图标

原文:WPF自定义控件 使用阿里巴巴图标

上一篇介绍了 WPF自定义控件
按钮 的初步使用，在进一步介绍WPF自定义控件
按钮之前，先介绍一下如何在WPF项目中使用阿里巴巴图标，方便以后做示例。

1.还是在上一篇项目基础上，在WPF自定义控件类库项目 Controls 文件夹下，新建一个资源字典（WPF）文件，取名： MyIcon.xaml ，并且添加如下代码:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:WpfCustomControlLibrary.Controls">

    <Style x:Key="MyIcon" TargetType="TextBlock">
        <Setter Property="FontFamily" Value="/WpfCustomControlLibrary;component/Resources/#iconfont"></Setter>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="TextAlignment" Value="Center"/>
        <Setter Property="HorizontalAlignment" Value="Center"/>
        <Setter Property="VerticalAlignment" Value="Center"/>
        <Setter Property="FontSize" Value="20"/>
    </Style>

</ResourceDictionary>

2.在项目下新建一个 Resources 文件夹，去阿里巴巴图标网站  http://www.iconfont.cn/ 下载 ttf 文件，放到该文件夹下，注意将此ttf文件的生成操作设置成 Resource ；

3.在Generic.xaml文件中，添加对MyIcon.xaml的引用：

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfCustomControlLibrary">

    <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary;component/Controls/MyButton1.xaml"/>
            <ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary;component/Controls/MyIcon.xaml" />
    </ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

4.在测试项目的 app.xaml 文件中加入MyIcon.xaml的引用：

<Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApplication1"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary;component/Controls/MyIcon.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

</Application>

5.在测试项目中加入一个textblock用以测试：

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication1"
        xmlns:controls="clr-namespace:WpfCustomControlLibrary.Controls;assembly=WpfCustomControlLibrary"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition></ColumnDefinition>
            <ColumnDefinition></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <Button Grid.Row="0" Grid.Column="0" Content="Default Button" Width="100" Height="50"></Button>
        <controls:MyButton1  Grid.Row="0" Grid.Column="1" Width="80" Height="80" >
            <controls:MyButton1.Content>
                <TextBlock Text="MyButton1" Margin="10,30,10,10"></TextBlock>
            </controls:MyButton1.Content>
        </controls:MyButton1>

        <TextBlock Grid.Row="1" Grid.Column="0" Text="" FontSize="50" Foreground="Green" Style="{StaticResource MyIcon}" ></TextBlock>

    </Grid>
</Window>

最终效果就是显示一个微信图标：

将这个icon图标和上一篇介绍的 MyButton1 结合起来使用，可以达到 图标按钮的效果，如：

1）将 MyButton1.xaml 改成：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:WpfCustomControlLibrary.Controls">

    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary;component/Controls/MyIcon.xaml" />
    </ResourceDictionary.MergedDictionaries>

    <ControlTemplate x:Key="MyButton1_Template" TargetType="{x:Type local:MyButton1}">
        <Border x:Name="border" Background="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path= Background}"
                                    Height="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Height}"
                                    CornerRadius="2"
                                    BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"
                                    Width="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Width}">
            <!--Icon/Text-->
            <StackPanel Orientation="Horizontal" VerticalAlignment="Center"
                        Margin="{TemplateBinding Padding}"
                        HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}">
                <TextBlock x:Name="icon"  Margin="3"
                           RenderTransformOrigin="0.5,0.5" Style="{StaticResource MyIcon}"
                           Text=""
                           FontSize="30"
                           Foreground="Green">
                    <TextBlock.RenderTransform>
                        <RotateTransform x:Name="transIcon" Angle="0"/>
                    </TextBlock.RenderTransform>
                </TextBlock>

                <TextBlock VerticalAlignment="Center"  x:Name="txt"
                           TextDecorations="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=ContentDecorations}"
                                               Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Content}" />
            </StackPanel>
        </Border>
    </ControlTemplate>

    <Style TargetType="{x:Type local:MyButton1}">
        <Setter Property="Template" Value="{StaticResource MyButton1_Template}"/>
    </Style>

</ResourceDictionary>

2）测试代码改成：

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication1"
        xmlns:controls="clr-namespace:WpfCustomControlLibrary.Controls;assembly=WpfCustomControlLibrary"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition></ColumnDefinition>
            <ColumnDefinition></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <Button Grid.Row="0" Grid.Column="0" Content="Default Button" Width="100" Height="50"></Button>
        <controls:MyButton1  Grid.Row="0" Grid.Column="1" Width="100" Height="50" Content="MyButton1" Background="Orange" />
        <TextBlock Grid.Row="1" Grid.Column="0" Text="" FontSize="50" Foreground="Green" Style="{StaticResource MyIcon}" ></TextBlock>

    </Grid>
</Window>

那么 按钮将变成图标+文字的组合，如图：
