WPF之资源字典zz

最近在看wpf相关东西，虽然有过两年的wpf方面的开发经验，可是当时开发的时候，许多东西只知其一;不知其二，至今都是模模糊糊，框架基本是别人搭建，本身也就照着模板写写，如今许多东西慢慢的理解了，回顾之前的若干记忆，而后解决本身不懂的方面，在CSDN作记录，写下一些本身的理解，方便之后查阅：

    今天写的是关于wpf的资源字典里面作触发器，而后主界面进行调用：

   1： 首先创建了个wpf窗体程序WpfApplication1；工程里面自动生成App.xaml和MainWindow.xaml两个文件，这两个文件就不作介绍了，App.xaml会在下面用到。

    2：而后呢。通常都会将控件的触发器写成这样：

  <Button Name="btnUpdate" Grid.Row="1" Width="100" Height="30" Content="更 新"  Command="{Binding CmdCommand}" CommandParameter="{Binding Oberve}">
                <Button.Style>
                    <Style TargetType="{x:Type Button}">
                        <Style.Triggers>
                            <Trigger Property="Button.IsMouseOver" Value="True">
                                <Setter Property="Button.Foreground" Value="Blue"/>
                            </Trigger>
                            <Trigger Property="Button.IsPressed" Value="True">
                                <Setter Property="Button.Foreground" Value="Red"/>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </Button.Style>
        </Button>

  那么控件多的时候，就显得臃肿了，因而就想到了【资源字典】，在资源字典里面写这些，而后调用，新建了【Dictionary1.xaml】文件

将要是实现的式样写进它里面：

  <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="CircleButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Border.BorderThickness" Value="1,1,1,1" />
        <Setter Property="Border.CornerRadius" Value="3" />
        <Setter Property="Height" Value="36" />
        <Setter Property="Width" Value="36" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                        <Ellipse Fill="{TemplateBinding Background}"/>
                        <Ellipse>
                            <Ellipse.Fill>
                                <RadialGradientBrush>
                                    <GradientStop Offset="0" Color="#00000000"/>
                                    <GradientStop Offset="0.88" Color="#00000000"/>
                                    <GradientStop Offset="1" Color="#80000000"/>
                                </RadialGradientBrush>
                            </Ellipse.Fill>
                        </Ellipse>
                        <Ellipse Margin="10" x:Name="highlightCircle" >
                            <Ellipse.Fill >
                                <LinearGradientBrush >
                                    <GradientStop Offset="0" Color="#50FFFFFF"/>
                                    <GradientStop Offset="0.5" Color="#00FFFFFF"/>
                                    <GradientStop Offset="1" Color="#50FFFFFF"/>
                                </LinearGradientBrush>
                            </Ellipse.Fill>
                        </Ellipse>
                        <ContentPresenter x:Name="content" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="RenderTransform">
                        <Setter.Value>
                            <RotateTransform Angle="10"></RotateTransform>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="RenderTransformOrigin" Value="0.5,0.5"></Setter>
                    <Setter Property="Background" Value="#FF0CC030" />
                </Trigger>
                <Trigger Property="IsPressed" Value="True">
                    <Setter Property="Foreground" Value="Red"/>
                </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary>

     3：这下就用到App.xaml发挥做用了；App这个文件是协助运行主窗口的文件，在app文件里面将数据资源里面的东东引进：

   <Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionary1.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

  4：这样后，MainWindow.xaml文件中就能够引进数据字典里面的式样和触发器了；

        <Grid>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="157,119,0,0" Name="button1"
  Style="{StaticResource CircleButtonStyle}"//引进数据字典里面的式样
                VerticalAlignment="Top" Width="75" />
    </Grid>

生成以下效果：
