WP7工具包GestureService是否有高级替代品? [英] Is there a high level replacement for the WP7 Toolkit GestureService?

问题描述

我目前在一些应用程序中使用WP7 Takeit的GestureService，以便在Silverlight UI元素上执行Flick和Pinch/Zoom手势.但是，鉴于该服务已被弃用，我试图找到一个可以以类似方式执行所有低层计算的替换库.

I currently use the WP7 tookit's GestureService in a few of my applications in order to perform Flick and Pinch/Zoom gestures on Silverlight UI elements. However, seeing that the service has been deprecated, I am trying to find a replacement library that can do the perform all the low level calculations in a similar fashion.

我一直在读，迷上ManipulationDelta是必经之路，但我宁愿不去探究，如果我不必-有人知道吗?

I've been reading that hooking into ManipulationDelta is the way to go, but I'd rather not delve into that if I don't have to - is there an alternative that anyone is aware of?

推荐答案

您可以使用ManipulationStarted，ManipulationDelta和ManipulationCompleted-这是高级的.您还可以使用Touch.FrameReported-提供有关用户触摸的低级界面

you can use ManipulationStarted, ManipulationDelta and ManipulationCompleted - which are high level. you can also use Touch.FrameReported - which provides a low-level interface on user touch

我使用GestureService而不是自己滚动来进行缩放，轻拂和拖动

I use GestureService instead of rolling my own for pinch zoom, flick and drag

找到了更多可用于替换手势服务的内容.

Found some more stuff that can be used to replace gesture service.

// Scale the rectangle.
this.scale.ScaleX *= e.DeltaManipulation.Scale.X;
this.scale.ScaleY *= e.DeltaManipulation.Scale.Y;

// Move the rectangle.
this.translation.X += e.DeltaManipulation.Translation.X;
this.translation.Y += e.DeltaManipulation.Translation.Y;
