画布儿童不能拖出画布边界 [英] canvas children can't drag out of the canvas boundaries

问题描述

大家好，

这是克里希纳(Krishna)，我正在画布上的该应用程序中使用wpf应用程序，我绘制了不同的形状，然后拖动这些形状并调整这些元素的大小，但是当我通过鼠标选择一个形状并将该形状从该画布的外侧拖动时，我想限制画布中的那些元素，这些元素可以在画布边界中转换，但不能在画布外部翻译.

请任何人知道如何通过不跨越画布边界来控制画布中的孩子.

在此应用程序中使用了一些装饰概念，但是我对装饰是陌生的，所以请解释一下如何轻松理解并实现它.



谢谢与问候
