WPF提供了样式、模板、触发器、状态管理、矢量形状等方式,让我们不需要背景图片,也可以轻松定制控件的风格样式。下面是笔者针对Checkbox进行的样式定制,让“正确”绿得好看,让“错误”红的显眼。
本文提供了两种风格,如果不是很适应自己系统的整体风格,可以对样式代码进行修改。
(1)普通风格
资源样式代码:
class="brush:csharp;gutter:true;"> <Style x:Key="CheckStyle1" TargetType="{x:Type CheckBox}"> <Setter Property="Height" Value="40"/> <Setter Property="Width" Value="70"/> <Setter Property="Foreground" Value="White"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type CheckBox}"> <Border x:Name="ForegroundPanel" CornerRadius="4" BorderBrush="#d4d5d5" BorderThickness="1" Padding="0"> <DockPanel> <Border x:Name="CheckFlag" HorizontalAlignment="Left" VerticalAlignment="Center" CornerRadius="10" Margin="10,0,0,0" BorderThickness="1" Width="20" Height="20"> <Grid> <Path Visibility="Collapsed" Width="20" Height="20" x:Name="CheckMark" SnapsToDevicePixels="False" StrokeThickness="2" Stroke="White" Fill="White" Data="M 5 7 L 7 15 L 18 2 L 17 2 L 7 14 L 6 7 L 5 7"> </Path> <Path Visibility="Collapsed" Width="20" Height="20" x:Name="InderminateMark" SnapsToDevicePixels="False" StrokeThickness="3" Stroke="White" Data="M 5 5 L 15 15 M 5 15 L 15 5"> </Path> </Grid> </Border> <TextBlock x:Name="Content" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="2,0" /> </DockPanel> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal" /> <VisualState x:Name="MouseOver"></VisualState> <VisualState x:Name="Pressed"></VisualState> <VisualState x:Name="Disabled" /> </VisualStateGroup> <VisualStateGroup x:Name="CheckStates"> <VisualState x:Name="Checked"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="CheckMark"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Visible}" /> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Unchecked"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="InderminateMark"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Visible}" /> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Indeterminate"></VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Border> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter TargetName="ForegroundPanel" Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="1,0"> <GradientStop Color="#89b601" Offset="0.0"/> <GradientStop Color="#73a80c" Offset="1"/> </LinearGradientBrush> </Setter.Value> </Setter> <Setter TargetName="Content" Property="Text" Value="正确"/> <Setter TargetName="CheckFlag" Property="Background" Value="#559800"></Setter> <Setter TargetName="Content" Property="DockPanel.Dock" Value="Right"/> <Setter TargetName="CheckFlag" Property="DockPanel.Dock" Value="Left"/> </Trigger> <Trigger Property="IsChecked" Value="False"> <Setter TargetName="ForegroundPanel" Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="1,0"> <GradientStop Color="#edb200" Offset="0.0"/> <GradientStop Color="#ed9e00" Offset="1"/> </LinearGradientBrush> </Setter.Value> </Setter> <Setter TargetName="Content" Property="Text" Value="错误"/> <Setter TargetName="CheckFlag" Property="Background" Value="#F64708"></Setter> <Setter TargetName="Content" Property="DockPanel.Dock" Value="Right"/> <Setter TargetName="CheckFlag" Property="DockPanel.Dock" Value="Left"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>
主界面Checkbox控件对样式引用代码:
<CheckBox Style="{StaticResource CheckStyle1}"/>
(2)左右滑动风格
资源样式代码:
<Style x:Key="CheckStyle2" TargetType="{x:Type CheckBox}"> <Setter Property="Height" Value="40"/> <Setter Property="Width" Value="70"/> <Setter Property="Foreground" Value="White"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type CheckBox}"> <Border x:Name="ForegroundPanel" CornerRadius="4" BorderBrush="#d4d5d5" BorderThickness="1" Padding="0"> <DockPanel> <Border x:Name="CheckFlag" HorizontalAlignment="Left" VerticalAlignment="Center" CornerRadius="10" Margin="10,0,0,0" BorderThickness="1" Width="20" Height="20"> <Grid> <Path Visibility="Collapsed" Width="20" Height="20" x:Name="CheckMark" SnapsToDevicePixels="False" StrokeThickness="2" Stroke="White" Fill="White" Data="M 5 7 L 7 15 L 18 2 L 17 2 L 7 14 L 6 7 L 5 7"> </Path> <Path Visibility="Collapsed" Width="20" Height="20" x:Name="InderminateMark" SnapsToDevicePixels="False" StrokeThickness="3" Stroke="White" Data="M 5 5 L 15 15 M 5 15 L 15 5"> </Path> </Grid> </Border> <TextBlock x:Name="Content" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="2,0" /> </DockPanel> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal" /> <VisualState x:Name="MouseOver"></VisualState> <VisualState x:Name="Pressed"></VisualState> <VisualState x:Name="Disabled" /> </VisualStateGroup> <VisualStateGroup x:Name="CheckStates"> <VisualState x:Name="Checked"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="CheckMark"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Visible}" /> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Unchecked"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="InderminateMark"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Visible}" /> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Indeterminate"></VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Border> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter TargetName="ForegroundPanel" Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="1,0"> <GradientStop Color="#89b601" Offset="0.0"/> <GradientStop Color="#73a80c" Offset="1"/> </LinearGradientBrush> </Setter.Value> </Setter> <Setter TargetName="Content" Property="Text" Value="正确"/> <Setter TargetName="CheckFlag" Property="Background" Value="#559800"></Setter> <Setter TargetName="Content" Property="DockPanel.Dock" Value="Right"/> <Setter TargetName="CheckFlag" Property="DockPanel.Dock" Value="Left"/> </Trigger> <Trigger Property="IsChecked" Value="False"> <Setter TargetName="ForegroundPanel" Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="1,0"> <GradientStop Color="#edb200" Offset="0.0"/> <GradientStop Color="#ed9e00" Offset="1"/> </LinearGradientBrush> </Setter.Value> </Setter> <Setter TargetName="Content" Property="Text" Value="错误"/> <Setter TargetName="CheckFlag" Property="Background" Value="#F64708"></Setter> <Setter TargetName="Content" Property="DockPanel.Dock" Value="Right"/> <Setter TargetName="CheckFlag" Property="DockPanel.Dock" Value="Left"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>
