跟着官网敲的按钮相关的内容,还涉及了wpf很多其他的知识

1.创建基本按钮

    <Grid><StackPanel HorizontalAlignment="Left"><Button>Button1</Button><Button>Button2</Button><Button>Button3</Button></StackPanel></Grid>

2.设置基本属性

        有两种方式,直接在button后面添加 ,但是我这里有三个按钮,你在项目之中会有出现更多按钮的情况,所以我们这了选择另一种方式:写按钮的样式style

        这里在App.xaml下面进行创建style,即表示把这个style应用到全局:

        <!--创建样式--><Style TargetType="Button"><Setter Property="Width" Value="90"></Setter><Setter Property="Margin" Value="10"></Setter></Style>

        这里的TargetType表示目标对象即button,下面的setter是设计器,property是button拥有的属性,value是我们设置的值.

3. 设置渐变静态资源并运用到按钮上面

        x:Key = "B1" 是上面资源的命名,下面引用的是{StaticResource B1}

        <LinearGradientBrush x:Key="B1" StartPoint="0,0" EndPoint="1,1"><GradientStop Color="DarkGray" Offset="0"></GradientStop><GradientStop Color="#CCCCFF" Offset="0.5"></GradientStop><GradientStop Color="DarkGray" Offset="1"></GradientStop></LinearGradientBrush><Style TargetType="{x:Type Button}"><Setter Property="Background" Value="{StaticResource B1}"></Setter><Setter Property="Width" Value="80"></Setter><Setter Property="Margin" Value="10"></Setter></Style>

4.模板自定义按钮外观

        更改按钮呈现：自定义模板。 添加以下突出显示的标记。 此标记指定两个具有圆角的 Rectangle 元素，后跟一个 DockPanel。 DockPanel 用于托管按钮的 ContentPresenter。 ContentPresenter 显示按钮的内容。 在本演练中，内容为文本（“Button 1”、“Button 2”、“Button 3”）。 所有模板组件（矩形和 DockPanel）都布置在 Grid 内.

 <Setter Property="Template"><Setter.Value><ControlTemplate TargetType="Button"><!--使用了Grid布局容器来组织按钮的内部元素。Width和Height属性被绑定到模板自身的宽度和高度，确保Grid的大小与按钮的大小相匹配。ClipToBounds设置为True，意味着任何超出Grid边界的内容都会被裁剪。--><Grid Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" ClipToBounds="True"><!-- Outer Rectangle with rounded corners. --><Rectangle x:Name="outerRectangle" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Stroke="{TemplateBinding Background}" RadiusX="20" RadiusY="20" StrokeThickness="5" Fill="Transparent" /><!-- Inner Rectangle with rounded corners. --><Rectangle x:Name="innerRectangle" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Stroke="Transparent" StrokeThickness="20" Fill="{TemplateBinding Background}" RadiusX="20" RadiusY="20" /><!-- Present Content (text) of the button. --><DockPanel Name="myContentPresenterDockPanel"><ContentPresenter x:Name="myContentPresenter" Margin="20" Content="{TemplateBinding  Content}" TextBlock.Foreground="Black" /></DockPanel></Grid></ControlTemplate></Setter.Value></Setter>

 

5.设置触发器

<ControlTemplate.Triggers><!-- Set properties when mouse pointer is over the button. --><Trigger Property="IsMouseOver" Value="True"><!-- Below are three property settings that occur when thecondition is met (user mouses over button).  --><!-- Change the color of the outer rectangle when user          mouses over it. --><Setter Property ="Rectangle.Stroke" TargetName="outerRectangle"Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" /><!-- Sets the glass opacity to 1, therefore, the          glass "appears" when user mouses over it. --><Setter Property="Rectangle.Opacity" Value="1"       TargetName="glassCube" /><!-- Makes the text slightly blurry as though you were          looking at it through blurry glass. --><Setter Property="ContentPresenter.BitmapEffect"       TargetName="myContentPresenter"><Setter.Value><BlurBitmapEffect Radius="1" /></Setter.Value></Setter></Trigger><!-- Set properties when button has focus. --><Trigger Property="IsFocused" Value="true"><Setter Property="Rectangle.Opacity" Value="1"       TargetName="glassCube" /><Setter Property="Rectangle.Stroke" TargetName="outerRectangle"       Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" /><Setter Property="Rectangle.Opacity" Value="1" TargetName="glassCube" /></Trigger></ControlTemplate.Triggers>
