wpf之样式

在Window.Resources中书写样式 ；

<Window.Resources>
<Style TargetType="Button" >

</Style>
</Window.Resources>

TargetType 是指定标签的类型 ；

<Style TargetType="Button" >

</Style>中的style样式会在所有的button按钮中生效 ；

 <Window.Resources>
        <Style TargetType="Button" >
            <Setter Property="FontSize" Value="18"></Setter>
            <Setter Property="Content" Value="BUTTON"></Setter>
            <Setter Property="Background" Value="red"></Setter>
            <!-- 字体 -->
            <Setter Property="Foreground" Value="white"></Setter>
        </Style>
    </Window.Resources>
    <Grid>
        <StackPanel>
            <Button />
            <Button />
            <Button />
            <Button />
        </StackPanel>
    </Grid>

x:key 可以给一个Style一个唯一的标识（类名）可以单独设置某一个button的样式，而不是现在给所有的button都设置了样式 ；

比如：

 <Window.Resources>
        <Style x:Key="ButtonStyle" TargetType="Button" >
            <Setter Property="FontSize" Value="18"></Setter>
            <Setter Property="Content" Value="BUTTON"></Setter>
            <Setter Property="Background" Value="red"></Setter>
            <!-- 字体 -->
            <Setter Property="Foreground" Value="white"></Setter>
        </Style>
    </Window.Resources>
    <Grid>
        <StackPanel>
            <Button Style="{StaticResource ButtonStyle}" />
            <Button />
            <Button   Style="{StaticResource ButtonStyle}" />
            <Button />
        </StackPanel>
    </Grid>

 样式：静态资源

如果想要从这些样式提取公共的样式复用，一些样式单独使用：比如给四个按钮不同的字体颜色 ；

<Window x:Class="WpfApp1.MainWindow"

        </Style>
    </Window.Resources>
    <Grid>

            <Button   Style="{StaticResource ButtonStyle3}" />
            <Button Style="{StaticResource ButtonStyle4}" />
        </StackPanel>
    </Grid>
</Window>
