Question

我正在尝试在UWP Windows 10中创建一个带有白色边框和透明背景（如Windows 8.1中的旧AppBarButtons）的圆形按钮。

我找到了几个这样的样本：

https://comentsys.wordpress.com/2015/05/23/windows-10-universal-windows-platform-custom-button/

https://social.msdn.microsoft.com/Forums/sqlserver/en-US/cda7a526-5e99-4d4a-a73c-0be4ce77f961/uwpwindows10-how-to-make-button-with-round-edges?forum=wpdevelop&prof=required

但问题在于边境。当我将BorderBrush设置为某种颜色时，结果是边框适用于Button＆＃34; Rectangle＆＃34;。

有没有办法为按钮创建圆形边框？

Are you looking for something like this?

<StackPanel>
    <Button Background="Transparent">
        <StackPanel>
            <Border CornerRadius="10" 
                    Background="Transparent" 
                    BorderBrush="White" 
                    BorderThickness="3">
                <TextBlock Text="MyButton" 
                           Margin="10" 
                           Foreground="White"/>
            </Border>
        </StackPanel>
    </Button>
</StackPanel>

实现此目的的方法很少，一种方法可以使用样式 - 从 ContentPresenter 中删除 BorderBrush 并添加 Ellipse 用那把刷子。 XAML中的示例：

<Page.Resources>
    <Style x:Key="CircleButtonStyle" TargetType="Button">
        <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}"/>
        <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
        <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}"/>
        <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}"/>
        <Setter Property="Padding" Value="8,4,8,4"/>
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="VerticalAlignment" Value="Center"/>
        <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
        <Setter Property="FontWeight" Value="Normal"/>
        <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
        <Setter Property="UseSystemFocusVisuals" Value="True"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid x:Name="RootGrid">
                       <VisualStateManager.VisualStateGroups>

                                        </ObjectAnimationUsingKeyFrames>

                        <ContentPresenter x:Name="ContentPresenter" VerticalAlignment="Center" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" Content="{TemplateBinding Content}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Ellipse x:Name="BorderCircle" Stroke="{TemplateBinding BorderBrush}" StrokeThickness="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Button Content="text" Width="50" Height="50" BorderBrush="Blue" Style="{StaticResource CircleButtonStyle}"/>
</Grid>

我还在 VisualStates 中进行了一些更改，以便在点击/禁用后看起来并不奇怪。

Answer 3

我不知道OP是否仍然对圆角按钮感兴趣，但是出于完整性考虑，我认为这可能对其他用户有所帮助，正如peterincumbria用户所说的那样，这是针对Windows的最新版本的10（1809）在Control类中有一个新属性：CornerRadius。因此，现在下面的代码就足够了：

<Button Content="DEMO"
        Background="Transparent"                    
        BorderThickness="1.0"
        BorderBrush="White"
        CornerRadius="10"
        HorizontalAlignment="Center"
        VerticalAlignment="Center"/>

将其放在Grid内，我们在Page的中间有一个圆角按钮。

或创建完全可自定义的cornerradius

        this.DefaultStyleKey = typeof(CustomRoundedButton);

    }
    public CornerRadius CornerRadius
    {

        set { SetValue(CornerRadiusProperty, value); }
    }
    public static readonly DependencyProperty CornerRadiusProperty =
        DependencyProperty.Register("CornerRadius", typeof(CornerRadius), typeof(CustomRoundedButton), new PropertyMetadata(new CornerRadius(10,10,10,10)));

Answer 5

我刚才使用的方法是简单地将CornerRadius添加到Button模板的“ RootGrid”网格中。

onException(YourException.class)
                .maximumRedeliveries(3) // You can call some method too
                .redeliveryDelay(100) // You can call some method too
                .onRedelivery(exchange -> {
                    int retryCount = exchange.getIn().getHeader(Exchange.REDELIVERY_COUNTER, Integer.class);
                    log.debug("Recoverable exception occurred. Retried {} time " , retryCount);
                })
                .retryAttemptedLogLevel(LoggingLevel.DEBUG)
                .to("someOtherRoute // Probably to error-topic

Answer 6

在1809版及更高版本中（即使您的目标是以下类似的较早版本），也可以仅以圆形按钮为例：

<Button
    Content="Stuff"
    Windows10version1809:CornerRadius="90,90,90,90"
    Height="64"
    Width="64">
</Button>

瞧！
