问题描述
例如,当发生点击时,我尝试缓慢地将带有动画的椭圆围绕(0,0)旋转.为此,我在RotateTransform.AngleProperty上使用DoubleAnimation,如下所示:
i try to rotate a ellipse with animation around (0,0) slowly for example when a click occured. for this i use DoubleAnimation on RotateTransform.AngleProperty like this :
DoubleAnimation da = new DoubleAnimation();
da.Duration = new Duration(TimeSpan.FromSeconds(2));
da.To = -50;
RotateTransform rt = new RotateTransform();
rt.BeginAnimation(RotateTransform.AngleProperty, da);
rt.CenterX = ellipse.Width / 2 - ellipse.Margin.Left / 2;
rt.CenterY = ellipse.Height / 2 - ellipse.Margin.Top / 2;
ellipse.RenderTransform = rt;
但是当完成修复时,椭圆的Margin属性不会改变.
我想在动画结束到新位置后动态更改边距.
怎么办?
谢谢.
but when aniamtion finished Margin property of ellipse not change.
i want to dynamically change Margin when animation finished to the new location.
how do it?
thanks.
推荐答案
我没看到问题.属性System.Windos.FrameworkElement.Margin
是类型为System.Windows.Thickness
的读/写属性;因此您可以自由为其分配新值.计算动画结束后期望的值,并将其分配给您的Ellipse
或其他形状:

I don''t see a problem. The propertySystem.Windos.FrameworkElement.Margin
is a read/write property of the typeSystem.Windows.Thickness
; so you can freely assign a new value to it. Calculate the value you expect to have after the end of animation and assign it to yourEllipse
or other shape:
