在WPF的色彩过渡 [英] Color transition in WPF
本文介绍了在WPF的色彩过渡的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想打一个WPF窗口的背景
颜色的颜色过渡。
如何我能做到这一点
例如:
刷i_color = Brushes.Red; //这是初始颜色
刷f_color = Brushes.Blue; //这是最后的颜色
当我点击按钮
按钮1
私人无效的button1_Click(对象发件人,RoutedEventArgs E)
{
本。背景= f_color; //这里过渡的开始。我不希望要快。也许4秒的间隔。
}
解决方案
在代码中是可以做到的与此
私人无效的button1_Click(对象发件人,RoutedEventArgs E)
{
ColorAnimation CA =新ColorAnimation (Colors.Red,Colors.Blue,新的持续时间(TimeSpan.FromSeconds(4)));
Storyboard.SetTarget(CA,这一点);
Storyboard.SetTargetProperty(CA,新的PropertyPath(Background.Color));
故事板STB =新的故事板();
stb.Children.Add(CA);
stb.Begin();
}
由于H.B.指出这将工作太
私人无效的button1_Click(对象发件人,RoutedEventArgs E)
{
ColorAnimation CA =新ColorAnimation(Colors.Blue,新的持续时间(TimeSpan.FromSeconds(4)));
this.Background =新的SolidColorBrush(Colors.Red);
this.Background.BeginAnimation(SolidColorBrush.ColorProperty,CA);
}
I want to make a color transition of Background
color of a WPF window.
How can I do this?
For example:
Brush i_color = Brushes.Red; //this is the initial color
Brush f_color = Brushes.Blue; //this is the final color
When I click on Button
button1
private void button1_Click(object sender, RoutedEventArgs e)
{
this.Background = f_color; //here the transition begins. I don't want to be quick. Maybe an interval of 4 seconds.
}
解决方案
In code it can be done with this
private void button1_Click(object sender, RoutedEventArgs e)
{
ColorAnimation ca = new ColorAnimation(Colors.Red, Colors.Blue, new Duration(TimeSpan.FromSeconds(4)));
Storyboard.SetTarget(ca, this);
Storyboard.SetTargetProperty(ca, new PropertyPath("Background.Color"));
Storyboard stb = new Storyboard();
stb.Children.Add(ca);
stb.Begin();
}
As H.B. pointed out this will work too
private void button1_Click(object sender, RoutedEventArgs e)
{
ColorAnimation ca = new ColorAnimation(Colors.Blue, new Duration(TimeSpan.FromSeconds(4)));
this.Background = new SolidColorBrush(Colors.Red);
this.Background.BeginAnimation(SolidColorBrush.ColorProperty, ca);
}
