我正在尝试使以下PointerOver
VisualState 工作。理想情况下,当鼠标指针悬停在按钮上时,我想用黑色边框突出显示按钮。
我一直在尝试各种方法来完成这项工作,请帮忙。
注意:如果我设置 BorderHighlight、Border 元素的 BorderColor 值,我会得到所需的边框,但当我将它作为 VisualState 的一部分时却没有。
<Style x:Key="SecondaryButton" TargetType="Button">
<Setter Property="Background" Value="LightSkyBlue"></Setter>
<Setter Property="Foreground" Value="Black"></Setter>
<Setter Property="Padding" Value="5"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Height="{TemplateBinding Height}" Width="{TemplateBinding Width}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" x:Name="ButtonHighlight" BorderThickness="2" BorderBrush="Transparent">
<Grid>
<Rectangle x:Name="innerRectangle" HorizontalAlignment="Stretch"
VerticalAlignment="Stretch" Stroke="Transparent"
StrokeThickness="20" Fill="{TemplateBinding Background}"
RadiusX="15" RadiusY="15" />
<ContentPresenter x:Name="Text" Content="{TemplateBinding Content}" VerticalAlignment="Center" HorizontalAlignment="Center"/>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal">
<Storyboard>
<ColorAnimation From="Transparent" To="Black" Storyboard.TargetName="Text" Storyboard.TargetProperty="(Button.Foreground).(SolidColorBrush.Color)" BeginTime="0" Duration="1"></ColorAnimation>
<ColorAnimation From="Transparent" To="LightSkyBlue" Storyboard.TargetName="Text" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)" BeginTime="0" Duration="1"></ColorAnimation>
</Storyboard>
</VisualState>
<VisualState x:Name="PointerOver">
<Storyboard>
<ColorAnimation From="Transparent" To="Black" Storyboard.TargetName="ButtonHighlight" Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" Duration="0:0:1"></ColorAnimation>
</Storyboard>

我剪掉了多余的代码以使问题简短明了,但这一切都可以编译,只是没有得到所需的结果。我也可以使用 2 个矩形(一个比另一个小),但想让它与实际边框一起使用。
此外,定位之间有什么区别:
<ColorAnimation From="Transparent" To="Black"
Storyboard.TargetName="ButtonHighlight"
Storyboard.TargetProperty="BorderBrush.(SolidColorBrush.Color)"
Duration="0:0:1"></ColorAnimation>
和
<ColorAnimation From="Transparent" To="Black"
Storyboard.TargetName="ButtonHighlight"
Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)"
Duration="0:0:1"></ColorAnimation>
