VisualTransition 类

定义

表示当控件从一个状态转换到另一个状态时发生的可视行为。Represents the visual behavior that occurs when a control transitions from one state to another.

示例

下面的示例创建一个VisualTransition , 它指定当用户将鼠标移出控件时, 控件的边框将更改为蓝色, 然后更改为黄色, 然后在1.5 秒内更改为黑色。The following example creates a VisualTransition that specifies that when the user moves the mouse away from the control, the control's border changes to blue, then to yellow, and then to black in 1.5 seconds. 有关完整示例, 请参阅通过创建 System.windows.controls.controltemplate> 自定义现有控件的外观For the entire example, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate.

<!--Take one and a half seconds to transition from the
    MouseOver state to the Normal state. 
    Have the SolidColorBrush, BorderBrush, fade to blue, 
    then to yellow, and then to black in that time.-->
<VisualTransition From="MouseOver" To="Normal" 
                      GeneratedDuration="0:0:1.5">
  <Storyboard>
    <ColorAnimationUsingKeyFrames
      Storyboard.TargetProperty="Color"
      Storyboard.TargetName="BorderBrush"
      FillBehavior="HoldEnd" >

      <ColorAnimationUsingKeyFrames.KeyFrames>

        <LinearColorKeyFrame Value="Blue" 
          KeyTime="0:0:0.5" />
        <LinearColorKeyFrame Value="Yellow" 
          KeyTime="0:0:1" />
        <LinearColorKeyFrame Value="Black" 
          KeyTime="0:0:1.5" />

      </ColorAnimationUsingKeyFrames.KeyFrames>
    </ColorAnimationUsingKeyFrames>
  </Storyboard>
</VisualTransition>

注解

通过添加VisualTransition对象在状态之间转换时, 可以指定控件的可视行为。You can specify the visual behavior of a control when it transitions between states by adding VisualTransition objects. 当你创建VisualTransition时, 你可以指定以下一个或多个:When you create a VisualTransition, you specify one or more of the following:

  • 通过设置GeneratedDuration属性, 在状态之间进行转换所花费的时间。The time it takes for a transition between states to occur by setting the GeneratedDuration property.

  • 在转换时, 通过设置Storyboard属性来对控件外观进行的其他更改。Additional changes in the control's appearance that occur at the time of the transition by setting the Storyboard property.

  • 当通过To设置和From属性来应用时。 VisualTransitionWhen the VisualTransition is applied by setting the To and From properties.
