一.前言
申明:WPF自定义控件与样式是一个系列文章,前后是有些关联的,但大多是按照由简到繁的顺序逐步发布的等,若有不明白的地方可以参考本系列前面的文章,文末附有部分文章链接。
本文主要内容:
- CheckBox复选框的自定义样式,有两种不同的风格实现;
- RadioButton单选框自定义样式,有两种不同的风格实现;
二. CheckBox自定义样式
2.1 CheckBox基本样式
标准CheckBox样式代码如下,实现了三态的显示,其中不同状态的图标用了字体图标(关于字体图标,可以参考本文末尾附录链接)
<Style x:Key="DefaultCheckBox" TargetType="{x:Type CheckBox}"> <Setter Property="Background" Value="Transparent"></Setter> <Setter Property="Foreground" Value="{StaticResource TextForeground}"></Setter> <Setter Property="Padding" Value="0"></Setter> <Setter Property="local:ControlAttachProperty.FIconMargin" Value="1, 1, 3, 1"></Setter> <Setter Property="local:ControlAttachProperty.FIconSize" Value="22"></Setter> <Setter Property="FontSize" Value="{StaticResource FontSize}"></Setter> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type CheckBox}"> <Grid x:Name="grid" Margin="{TemplateBinding Padding}" VerticalAlignment="Center"> <StackPanel Orientation="Horizontal" VerticalAlignment="Center"> <TextBlock x:Name="icon" Style="{StaticResource FIcon}" Text="" FontSize="{TemplateBinding local:ControlAttachProperty.FIconSize}" Margin="{TemplateBinding local:ControlAttachProperty.FIconMargin}" Foreground="{TemplateBinding Foreground}"/> <ContentPresenter VerticalAlignment="Center"/> </StackPanel> </Grid> <!--触发器:设置选中状态符号--> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="true"> <Setter Property="Text" Value="" TargetName="icon" ></Setter> <Setter Property="Foreground" Value="{StaticResource CheckedForeground}"></Setter> </Trigger> <Trigger Property="IsChecked" Value="{x:Null}"> <Setter Property="Text" Value="" TargetName="icon" ></Setter> </Trigger> <Trigger Property="IsMouseOver" Value="true"> <Setter Property="Foreground" Value="{StaticResource MouseOverForeground}"></Setter> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="grid" ></Setter> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </
