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="&#xe6f0;" 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="&#xe6f0;"                           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="&#xe6f0;" 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:
