WPF-使按钮的下沉效果变慢

我在WPF中有一个按钮，当单击按钮时会创建一个凹陷效果。 我想知道是否有一个属性使效果显得更慢而不是默认速度？

这是我的代码：

private void btnEnglish_PreviewMouseDown(object sender, MouseButtonEventArgs e) { btnEnglish.BorderThickness = new Thickness(10, 10, 0, 0); } 

Answer 1

您可以使用厚度动画：

 private void btnEnglish_PreviewMouseDown(object sender, MouseButtonEventArgs e) { ThicknessAnimation myThicknessAnimation = new ThicknessAnimation(); myThicknessAnimation.Duration = TimeSpan.FromSeconds(1); myThicknessAnimation.From = new Thickness(0,0,0,0); myThicknessAnimation.To = new Thickness(10,10,0,0); btnEnglish.BeginAnimation(Button.BorderThicknessProperty, myThicknessAnimation); } 

编辑：

因为您希望按钮返回默认位置

 private void btnEnglish_Click(object sender, RoutedEventArgs e) { ThicknessAnimation myThicknessAnimation = new ThicknessAnimation(); myThicknessAnimation.Duration = TimeSpan.FromSeconds(0.5); myThicknessAnimation.From = new Thickness(0,0,0,0); myThicknessAnimation.To = new Thickness(10,10,0,0); myThicknessAnimation.AutoReverse = true; myThicknessAnimation.Completed += (arg, s) => { btnEnglish.BeginAnimation(Button.BorderThicknessProperty, null); }; btnEnglish.BeginAnimation(Button.BorderThicknessProperty, myThicknessAnimation); } 

Answer 2

使用厚度动画而不是显式的PreviewMouseDownEvent
