Como: Animate a Beveled Visual Effect

  • Artigo

This example shows how to animate a BevelBitmapEffect on a button.

Exemplo

The following example shows how to animate the BevelWidth and LightAngle properties of a BevelBitmapEffect. As a result, when the mouse pointer moves over the Button, the inner level of the bevel increases while the artificial light source that is used for the bevel, revolves around the Button.

  <StackPanel>

    <Button Width="200" Height="80" Margin="50">
      MouseOver ME!
      <Button.BitmapEffect>

        <!-- This BitmapEffect is targeted by the animation. -->
        <BevelBitmapEffect x:Name="myBevelBitmapEffect" BevelWidth="0" EdgeProfile="CurvedIn"  />
      </Button.BitmapEffect>
      <Button.Triggers>
        <EventTrigger RoutedEvent="Button.MouseEnter">
          <BeginStoryboard>
            <Storyboard>

              <!-- Animate the BevelWidth from 0 to 15. -->
              <DoubleAnimation
               Storyboard.TargetName="myBevelBitmapEffect"
               Storyboard.TargetProperty="BevelWidth"
               From="0" To="15" Duration="0:0:0.5" AutoReverse="True"
               />

              <!-- Animate the LightAngle so that the light source and 
                   corresponding bevel shadows move around the button. -->
              <DoubleAnimation
               Storyboard.TargetName="myBevelBitmapEffect"
               Storyboard.TargetProperty="LightAngle"
               From="360" To="0" Duration="0:0:0.5" AutoReverse="True"
               />
            </Storyboard>
          </BeginStoryboard>
        </EventTrigger>
      </Button.Triggers>
    </Button>

  </StackPanel>
