[英]Disable Storyboard or Animation in WPF
我创建了一个带有动画和一些消息的简单通知窗口。 但是,我可以禁用动画或情节提要吗? MouseEnter事件,例如Facebook通知。 逐渐降低不透明度,当我在窗口上拖动鼠标时,将不透明度设置为100%。 怎么做? 这是一个xaml代码:
WindowStyle="None" AllowsTransparency="True" Background="Transparent" >
<Grid x:Name="gridData" RenderTransformOrigin="0,1" MouseRightButtonDown="Window_MouseRightButtonDown" MouseEnter="Grid_MouseEnter">
<Border BorderThickness="1" Background="SkyBlue" BorderBrush="Black" CornerRadius="10">
<StackPanel Margin="20">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="32"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="40"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="txtTitle" Grid.Row="0" Grid.Column="0" Text="" FontWeight="Bold" VerticalAlignment="Center"/>
<Image x:Name="image" Grid.Row="0" Grid.Column="1" HorizontalAlignment="Left" Visibility="Collapsed"/>
<TextBlock x:Name="txtMessage" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Text="" TextWrapping="Wrap"/>
</Grid>
</StackPanel>
</Border>
<Grid.Triggers>
<EventTrigger RoutedEvent="FrameworkElement.Loaded" >
<BeginStoryboard >
<Storyboard>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleY)">
<SplineDoubleKeyFrame KeyTime="0:0:0" Value="0"/>
<SplineDoubleKeyFrame KeyTime="0:0:0.5" Value="1"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)">
<SplineDoubleKeyFrame KeyTime="0:0:2" Value="1"/>
<SplineDoubleKeyFrame KeyTime="0:0:4" Value="0"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Grid.Triggers>
<Grid.RenderTransform>
<ScaleTransform ScaleY="1" />
</Grid.RenderTransform>
</Grid>
为您的BeginStoryboard
添加一个名称:
<BeginStoryboard Name="ScaleAndFadeOut">
然后为另一个事件添加另一个事件触发器,并使用StopStoryboard
元素:
<Grid.Triggers>
<EventTrigger RoutedEvent="FrameworkElement.Loaded">
...
</EventTrigger>
<EventTrigger RoutedEvent="FrameworkElement.MouseMove">
<StopStoryboard BeginStoryboardName="ScaleAndFadeOut" />
</EventTrigger>
</Grid.Triggers>
