我正在尝试使用代码隐藏同时为a TranslateTransform和ScaleTransforma 设置动画.我研究了一些类似的问题,但我有些问题,我仍然坚持第一步.RectangleStoryBoard
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Rectangle x:Name="MyRectangle" Width="100" Height="100" Fill="Aqua"></Rectangle>
<Button Grid.Row="1" Content="Animate" Click="ButtonBase_OnClick"/>
</Grid>
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
var translate_x = new DoubleAnimation()
{
From = 0,
To = 100,
Duration = TimeSpan.FromSeconds(5),
};
var translate_y = new DoubleAnimation()
{
From = 0,
To = 100,
Duration = TimeSpan.FromSeconds(5),
};
var scale_x = new DoubleAnimation()
{
From = 1,
To = 2,
Duration = TimeSpan.FromSeconds(5),
}; …这应该是相当简单的,但我似乎无法做到正确.我有一个集合System.Windows.Controls.Image.当我选择其中一个时,我希望所有其他人都能获得不透明度0.5.我正在使用MVVM,这背后的逻辑(找到所选图像并将其设置为Enabled)已完成ViewModel,并且正在运行.所以基本上这是有效的:
<Image Grid.Row="0" Source="{Binding ItemImage}" IsEnabled="{Binding ItemImageEnabled}">
<Image.Style>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="0.5"/>
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="Opacity" Value="1.0"/>
</Trigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
现在我想的不透明度转变到进行动画,从衰落它1.0到0.5当没有选择图像,和从衰落0.5到1.0当它.我会想到这会工作:
<Image Grid.Row="0" Source="{Binding ItemImage}" IsEnabled="{Binding ItemImageEnabled}">
<Image.Style>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0.5" BeginTime="0:0:0" Duration="0:0:1"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" …我是 WPF 新手，我只想为两个对象一个接一个地制作动画。这意味着第二个动画应该在第一个动画完成后开始。我尝试使用计时器和睡眠方法，但效果不佳。下面是示例代码：
DoubleAnimation da1 = new DoubleAnimation()
{
From = 10,
To = 200,
Duration = new System.Windows.Duration(TimeSpan.FromSeconds(sec)),
};
temLabel1.BeginAnimation(Canvas.TopProperty, da1);
Delay(); // Delay when busy
DoubleAnimation da2 = new DoubleAnimation()
{
From = 300,
To = 500,
Duration = new System.Windows.Duration(TimeSpan.FromSeconds(sec)),
};
ItemLabels2.BeginAnimation(Canvas.LeftProperty, da2);
我用来Timer在两个动画之间创建时间延迟
/* Setting Timer For delay during animation */
timer.Interval = sec * 1000 + 50;
timer.Elapsed += Timer_Elapsed;
延迟函数的代码是：
void Delay()
{
busy = true;
timer.Start();
while (busy) {} …我正在尝试用故事板管理一个动画,它是一个闪烁的标签,并且实现了这个效果我已经使用了这个代码(动画我首选只在后面的代码中工作):我宣布我的故事板;
public partial class Example: Page
{
public Storyboard LabelStoryboard=new Storyboard();
}
然后我发布动画:
private void FlashWinLabel(){
DoubleAnimation Flash= new DoubleAnimation();
Flash.Duration = TimeSpan.FromMilliseconds(400);
Flash.From = 1.0d;
Flash.To = 0.0d;
Flash.RepeatBehavior = RepeatBehavior.Forever;
WinLabel.BeginAnimation(Label.OpacityProperty, Flash);
SolidColorBrush myAnimatedBrush = new SolidColorBrush();
myAnimatedBrush.Color = Colors.White;
WinLabel.Foreground = myAnimatedBrush;
this.RegisterName("MyAnimatedBrush", myAnimatedBrush);
ColorAnimation LabelColorAnimation = new ColorAnimation();
LabelColorAnimation.To = Colors.GreenYellow;
LabelColorAnimation.Duration = TimeSpan.FromMilliseconds(200);
LabelColorAnimation.RepeatBehavior = RepeatBehavior.Forever;
LabelColorAnimation.AutoReverse = true;
Storyboard.SetTargetName(LabelColorAnimation, "MyAnimatedBrush");
Storyboard.SetTargetProperty(
LabelColorAnimation, new PropertyPath(SolidColorBrush.ColorProperty));
LabelStoryboard.Children.Add(LabelColorAnimation);
WinLabel.BeginStoryboard(LabelStoryboard);
}
所有这一切都有效,直到这一点,当我试图通过按下屏幕上的按钮来停止故事板时出现问题:
private void StopStoryBoard()
{
LabelStoryboard.Stop();
} …
