【问题描述】:
所有,我有以下资源,这些资源定义了一个自定义 CheckBox 和用于选中/未选中状态的图像。
<sys:String x:Key="Up">
F1 M 37.8516,35.625L 34.6849,38.7917L 23.6016,50.2708L
23.6016,39.9792L 37.8516,24.9375L 52.1016,39.9792L 52.1016,
50.2708L 41.0182,38.7917L 37.8516,35.625 Z
</sys:String>
<sys:String x:Key="Down">
F1 M 37.8516,39.5833L 52.1016,24.9375L 52.1016,35.2292L
37.8516,50.2708L 23.6016,35.2292L 23.6016,24.9375L 37.8516,39.5833 Z
</sys:String>
<Style x:Key="styleCustomCheckBox" TargetType="{x:Type CheckBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<StackPanel Orientation="Horizontal">
<Path x:Name="MyPin" Width="18" Height="18" Stretch="Fill" Fill="#FF000000"
Data="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=(local:CustomCheckBoxClass.IsCheckedOnData)}" />
<ContentPresenter VerticalAlignment="Center" Margin="10,0,0,0" />
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="MyPin" Property="Data"
Value="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=(local:CustomCheckBoxClass.IsCheckedOffData)}" />
<Setter TargetName="MyPin" Property="Fill" Value="Gray" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这里使用如下
<StackPanel Orientation="Vertical" HorizontalAlignment="Center" Background="Beige">
<CheckBox Height="35"
local:CustomCheckBoxClass.IsCheckedOnData="{StaticResource Up}"
local:CustomCheckBoxClass.IsCheckedOffData="{StaticResource Down}"
Style="{StaticResource styleCustomCheckBox}"
Content="MySolution1" />
<CheckBox Height="35"
local:CustomCheckBoxClass.IsCheckedOnData="{StaticResource Up}"
local:CustomCheckBoxClass.IsCheckedOffData="{StaticResource Down}"
Style="{StaticResource styleCustomCheckBox}"
Content="MySolution2" />
</StackPanel>
我使用下面的DependencyPropertys 来支持这个
public class CustomCheckBoxClass : DependencyObject
{
public static readonly DependencyProperty IsCheckedOnDataProperty;
public static void SetIsCheckedOnData(DependencyObject DepObject, string value)
{
DepObject.SetValue(IsCheckedOnDataProperty, value);
}
public static string GetIsCheckedOnData(DependencyObject DepObject)
{
return (string)DepObject.GetValue(IsCheckedOnDataProperty);
}
public static readonly DependencyProperty IsCheckedOffDataProperty;
public static void SetIsCheckedOffData(DependencyObject DepObject, string value)
{
DepObject.SetValue(IsCheckedOffDataProperty, value);
}
public static string GetIsCheckedOffData(DependencyObject DepObject)
{
return (string)DepObject.GetValue(IsCheckedOffDataProperty);
}
static CustomCheckBoxClass()
{
PropertyMetadata MyPropertyMetadata = new PropertyMetadata(string.Empty);
IsCheckedOnDataProperty = DependencyProperty.RegisterAttached(
"IsCheckedOnData", typeof(string), typeof(CustomCheckBoxClass), MyPropertyMetadata);
IsCheckedOffDataProperty = DependencyProperty.RegisterAttached(
"IsCheckedOffData", typeof(string), typeof(CustomCheckBoxClass), MyPropertyMetadata);
}
}
现在我想知道如何扩展它,以便使用更详细的矢量图形。我有一些使用 Expression Design 创建的图形,并将它们导出为 XAML 文件。这些文件之一的标记是
<DrawingBrush x:Key="Layer_1" Stretch="Uniform">
<DrawingBrush.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
<GeometryDrawing Brush="#FF565656" Geometry="M 107.455,171.715L 107.455,29.3347L 220.225,29.3347L 220.225,171.715L 107.455,171.715 Z "/>
<GeometryDrawing Brush="#FF565656" Geometry="F1 M 152.5,298.345L 152.5,201.955L 175.18,201.955L 175.18,298.345L 152.5,298.345 Z "/>
<GeometryDrawing Brush="#FFFFFFFF" Geometry="M 124.15,172.975L 124.15,48.8647L 165.73,48.8647L 165.73,172.975L 124.15,172.975 Z "/>
<GeometryDrawing Brush="#FF565656" Geometry="F1 M 83.1999,208.885L 83.1999,162.895L 244.48,162.895L 244.48,208.885L 83.1999,208.885 Z "/>
</DrawingGroup.Children>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush>
如何将其包含在可直接在窗口/组件中使用的资源字典中? 我已尝试更改 DependencyProperty 以提供对 DrawingBrush 的访问,但我已更改XAML 到
<CheckBox Height="35"
local:CustomCheckBoxClass.IsCheckedOnData="{StaticResource Layer_1}"
local:CustomCheckBoxClass.IsCheckedOffData="{StaticResource Down}"
Style="{StaticResource styleCustomCheckBox}"
Content="MySolution1" />
我在哪里引用了相关的ResourceDictionary,但这不起作用。
感谢您的宝贵时间。
编辑。基于@HighCore 的评论。假设我有以下自定义Checkbox
<Style x:Key="MheckBox"
TargetType="{x:Type CheckBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<StackPanel Orientation="Horizontal">
<Image x:Name="imageCheckBox"
Width="16"
Height="16"
Source="F:\Camus\ResourceStudio\Graphics\Images\UnPinned16.png"/>
<ContentPresenter VerticalAlignment="Center"/>
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="imageCheckBox"
Property="Source"
Value="F:\Camus\ResourceStudio\Graphics\Images\Pinned16.png"/>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="imageCheckBox"
Property="Source"
Value="F:\Camus\ResourceStudio\Graphics\Images\UnPinned16.png"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
效果很好。 如何更改Value="F:\Camus\ResourceStudio\Graphics\Images\UnPinned16.png" 以使用我上面概述的矢量图形?
【问题讨论】:
-
你错了。我建议你开始阅读 Here 控制创作。
-
谢谢我会读这个。你能告诉我为什么你这么耐心地认为这种方法是错误的吗?再次感谢您的宝贵时间...这就是为什么我想“窥探”VS2012 的 XAML。我下载了 RedGate Reflector,但无法让 XAML 反射/反编译器工作。
-
如果您需要 CheckBox 样式,只需创建一个 CheckBox 样式。不需要附加属性。
-
我希望能够更改用于此类复选框的图像,以便我可以在需要时更改它们。这使我能够对其他事情使用相同的控件。上面的简单方法有效,我现在遇到的主要问题是使用包含在自己的资源文件/字典中的矢量图形......

@HighCore 你能快速看看我的编辑吗?
