【WPF】WPF(样式)

Window.Resources 当前窗体作用域资源

TargetType=“Button”

  使得当前窗体的组件类型都适配此样式

    <Window.Resources><Style TargetType="Button"><Setter Property="Background" Value="WhiteSmoke"></Setter><Setter Property="Margin" Value="20,10"></Setter><!--左右20 上下10--></Style></Window.Resources><StackPanel><Button Content="登录"  /><Button Content="退出"/><Button Content="忘记密码" /><Button Content="忘记密码" /></StackPanel>

x:Key=“loginStyle” 指定样式

    <Window.Resources><Style TargetType="Button"><Setter Property="Background" Value="WhiteSmoke"></Setter><Setter Property="Margin" Value="20,10"></Setter><!--左右20 上下10--></Style><Style x:Key="QuitStyle" TargetType="Button"><Setter Property="Background" Value="Red"></Setter><Setter Property="Width" Value="200"></Setter><Setter Property="Height" Value="50"></Setter></Style></Window.Resources><StackPanel><Button Content="登录"  /><Button Content="退出"  Style="{StaticResource QuitStyle}"/><Button Content="忘记密码" /><Button Content="忘记密码" /></StackPanel>

BasedOn=“{ StaticResource {x:Type Button}}” 继承样式

  继承通用样式后设置样式会覆盖继承的样式
