1、效果截图
拖动Slider,相应的灯光图片,字体颜色、大小都改变
2、前端代码
1 <Grid Height="224" Margin="0,561,0,205"> 2 <Image Stretch="Fill" Height="44" Source="/BirdDetect_Images/bar04.png" Margin="0,0,0,180"></Image> 3 <Label Content="灯光控制" Padding="15,8" Foreground="White" FontSize="18" FontFamily="Microsoft YaHei" Margin="0,0,0,180"></Label> 4 <Image Height="80" Width="80" Stretch="Fill" Source="{Binding BtnLight, Converter={StaticResource LightTypeToPicConverter} }" Margin="98,49,95,95"></Image> 5 <StackPanel Orientation="Horizontal" Margin="10,148,10,45"> 6 <TextBlock Text="关闭" TextAlignment="Center" FontSize="{Binding BtnLight, Converter={StaticResource LightSliderConverter},ConverterParameter=1}" FontFamily="Microsoft YaHei" Width="50" Foreground="{Binding BtnLight, Converter={StaticResource LightTypeToColorConverter},ConverterParameter=1}" ></TextBlock> 7 <TextBlock Text="弱光" TextAlignment="Center" FontSize="{Binding BtnLight, Converter={StaticResource LightSliderConverter},ConverterParameter=2}" FontFamily="Microsoft YaHei" Width="50" Foreground="{Binding BtnLight, Converter={StaticResource LightTypeToColorConverter},ConverterParameter=2}" ></TextBlock> 8 <TextBlock Text="中光" TextAlignment="Center" FontSize="{Binding BtnLight, Converter={StaticResource LightSliderConverter},ConverterParameter=3}" FontFamily="Microsoft YaHei" Width="50" Foreground="{Binding BtnLight, Converter={StaticResource LightTypeToColorConverter},ConverterParameter=3}" ></TextBlock> 9 <TextBlock Text="强光" TextAlignment="Center" FontSize="{Binding BtnLight, Converter={StaticResource LightSliderConverter},ConverterParameter=4}" FontFamily="Microsoft YaHei" Width="50" Foreground="{Binding BtnLight, Converter={StaticResource LightTypeToColorConverter},ConverterParameter=4}" ></TextBlock> 10 <TextBlock Text="爆闪" TextAlignment="Center" FontSize="{Binding BtnLight, Converter={StaticResource LightSliderConverter},ConverterParameter=5}" FontFamily="Microsoft YaHei" Width="50" Foreground="{Binding BtnLight, Converter={StaticResource LightTypeToColorConverter},ConverterParameter=5}" ></TextBlock> 11 </StackPanel> 12 <Slider x:Name="lightSlider" Value="{Binding BtnLight, Converter={StaticResource SliderToLightConverter}}" HorizontalAlignment="Left" Height="30" Margin="28,184,0,0" VerticalAlignment="Top" Width="216" Style="{DynamicResource LightSliderStyle2}" Maximum="5" Minimum="1" SmallChange="1" TickFrequency="1" IsSnapToTickEnabled="True" > 13 <i:Interaction.Triggers> 14 <i:EventTrigger EventName="LostMouseCapture"> 15 <Command:EventToCommand Command="{Binding SetSpeakerLightCmd}" /> 16 </i:EventTrigger> 17 </i:Interaction.Triggers> 18 </Slider> 19 <Image Stretch="Fill" Height="10" Source="/BirdDetect_Images/bar05.png" Margin="0,232,0,-18"></Image> 20 </Grid>

3)、LightSliderConverter
1 public class LightSliderValueConverter : IValueConverter 2 { 3 4 public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 5 { 6 LightType lt1 = (LightType)value; 7 LightType lt2 = (LightType)int.Parse(parameter.ToString()); 8 if (lt1 == lt2 ) 9 { 10 return 18; 11 } 12 else 13 { 14 return 15; 15 } 16 } 17 18 public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 19 { 20 throw new NotImplementedException(); 21 } 22 }
4)、LightTypeToColorConverter
1 public class LightTypeToColorConverter : IValueConverter 2 { 3 public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 4 { 5 LightType lt1 = (LightType)value; 6 LightType lt2 = (LightType)int.Parse(parameter.ToString()); 7 if (lt1 == lt2) 8 { 9 return "#FF1546EE"; 10 } 11 else 12 { 13 return "White"; 14 } 15 } 16 17 public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 18 { 19 throw new NotImplementedException(); 20 } 21 }
枚举
public enum LightType { [Description("关闭")] Close = 1, [Description("弱光")] Low = 2, [Description("中光")] Normal = 3, [Description("强光")] High = 4, [Description("爆闪")] Sharpflash = 5 }
