触发器触发触发后触发

Question

所以我试图制作一个按钮，当鼠标越过/ out / down / up时会改变图像....

并提出以下内容：

<Image>
    <Image.Style>
        <Style TargetType="{x:Type Image}">
            <Style.Triggers>
                <Trigger Property="IsEnabled" Value="True">
                    <Setter Property="Source" Value="/MyWPF;component/Resources/MediaPlayer/Play-Normal-icon.png"/>
                </Trigger>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Source" Value="/MyWPF;component/Resources/MediaPlayer/Play-Pressed-icon.png"/>
                </Trigger>
                <Trigger Property="IsMouseOver" Value="False">
                    <Setter Property="Source" Value="/MyWPF;component/Resources/MediaPlayer/Play-Normal-icon.png"/>
                </Trigger>
                <Trigger Property="IsEnabled" Value="False">
                    <Setter Property="Source" Value="/MyWPF;component/Resources/MediaPlayer/Play-Disabled-icon.png"/>
                </Trigger>
                <EventTrigger RoutedEvent="MouseDown">
                    <EventTrigger.Actions>
                        <BeginStoryboard>
                            <Storyboard>
                                <ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetProperty="Source" Duration="00:00:00.5">
                                    <DiscreteObjectKeyFrame KeyTime="00:00:00">
                                        <DiscreteObjectKeyFrame.Value>
                                            <BitmapImage UriSource="/MyWPF;component/Resources/MediaPlayer/Play-Hot-icon.png"/>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                            </Storyboard>
                        </BeginStoryboard>
                    </EventTrigger.Actions>
                </EventTrigger>
                <EventTrigger RoutedEvent="MouseUp">
                    <EventTrigger.Actions>
                        <BeginStoryboard>
                            <Storyboard>
                                <ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetProperty="Source" Duration="00:00:00.5">
                                    <DiscreteObjectKeyFrame KeyTime="00:00:00">
                                        <DiscreteObjectKeyFrame.Value>
                                            <BitmapImage UriSource="/MyWPF;component/Resources/MediaPlayer/Play-Normal-icon.png"/>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                            </Storyboard>
                        </BeginStoryboard>
                    </EventTrigger.Actions>
                </EventTrigger>
            </Style.Triggers>
        </Style>
    </Image.Style>
</Image>

鼠标过度/突出的工作。

但是，一旦我拍摄鼠标点击（向下），触发事件启发器，我可以看到图像已更改。

释放鼠标单击（向上），EventTriggers再次触发，我可以看到图像更改为假设的方式。

现在我鼠标过度/掉图像。它不再更改图像....

但是当我做鼠标下降时仍然工作...

所以我在某种程度上讨厌突击事件撤消了ismouseover触发器？

eventTrigger会覆盖其他触发器吗？

p.s.:对于那些读我以前的问题的人，对不起我不知道问题是因为按钮从数据绑定中禁用了问题。

这是因为依赖属性值优先级，要么更改其他触发器，要使单帧动画或使动画不是保持它们的值。
