我有一个WPF应用程序,我需要用户选择屏幕框的一个角和一个角。
对我来说,按钮的类型应该是单选按钮。一次只能选择一个角。
但是,在Windows和WPF中,单选按钮自然是圆形的。但是WPF允许某人重新设计UI元素(如果他们了解如何)。
有人可以告诉我如何重新设置样式。我希望看到它的完成方式不会影响同一窗口中其他单选按钮的外观。

要为RadioButton
设计样式,您需要将其ControlTemplate
更改为自定义样式。该link具有样本ControlTemplate
。我对其进行了调整,以使RadioButton
显示为正方形。这是简化的ControlTemplate
,因为它没有动画:
<Style x:Key="SquareRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="FocusVisualStyle" Value="{DynamicResource RadioButtonFocusVisual}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<BulletDecorator Background="Transparent">
<BulletDecorator.Bullet>
<Grid Width="13" Height="13">
<Rectangle
x:Name="Border"
StrokeThickness="1"
Stroke="Black"
Fill="White"
/>
<Rectangle
x:Name="CheckMark"
Fill="Black"
Visibility="Collapsed"
Margin="2"
/>
</Grid>
</BulletDecorator.Bullet>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver" />
<VisualState x:Name="Pressed" />
<VisualState x:Name="Disabled">
<Storyboard>
<ColorAnimationUsingKeyFrames
Storyboard.TargetName="Border"
Storyboard.TargetProperty="Stroke.Color"
>
<DiscreteColorKeyFrame KeyTime="0" Value="LightGray" />
</ColorAnimationUsingKeyFrames>
<ColorAnimationUsingKeyFrames
Storyboard.TargetName="CheckMark"
Storyboard.TargetProperty="Fill.Color"
>
<DiscreteColorKeyFrame KeyTime="0" Value="LightGray" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked" >
<Storyboard>
<ObjectAnimationUsingKeyFrames
Storyboard.TargetName="CheckMark"
Storyboard.TargetProperty="(UIElement.Visibility)"
>
<DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Visible}" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Unchecked" />
<VisualState x:Name="Indeterminate" />
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter
Margin="4,0,0,0"
VerticalAlignment="Center"
HorizontalAlignment="Left"
RecognizesAccessKey="True"
/>
</BulletDecorator>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
然后可以将其应用于要设置样式的RadioButton
:
<RadioButton Style="{StaticResource SquareRadioButton}" Content="Option 1" />
