问题描述
我刚接触 WPF 和 XAML,所以我有 ResourceDictionary
(现在只有一个按钮):
I new to WPF and XAML, so I have ResourceDictionary
(one button for now):
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="ButtonProduct" TargetType="Button">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border"
CornerRadius="0"
BorderThickness="0"
Focusable="False"
BorderBrush="Transparent" Background="White">
<ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="#52b0ca"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
悬停时按钮的颜色会发生变化,但如何更改淡入淡出以实现颜色的平滑过渡?
On hover the color of the button changes, but how can I make change in fade in and out, for smooth transition of the color?
推荐答案
您可以使用 EventTrigger
在 MouseEnter
和 上启动
:ColorAnimation
>鼠标离开
You can use EventTrigger
to start ColorAnimation
on MouseEnter
and MouseLeave
:
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border" CornerRadius="0" BorderThickness="0" Focusable="False" BorderBrush="Transparent" Background="White">
<ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<EventTrigger RoutedEvent="MouseEnter">
<BeginStoryboard>
<Storyboard>
<ColorAnimation From="White" To="#52b0ca" Duration="0:0:1" Storyboard.TargetName="Border" Storyboard.TargetProperty="Background.Color"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="MouseLeave">
<BeginStoryboard>
<Storyboard>
<ColorAnimation From="#52b0ca" To="White" Duration="0:0:1" Storyboard.TargetName="Border" Storyboard.TargetProperty="Background.Color"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
