本文整理了Java中org.eclipse.swt.graphics.Point类的一些代码示例，展示了Point类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Point类的具体详情如下：
包路径：org.eclipse.swt.graphics.Point
类名称：Point

Point介绍

[英]Instances of this class represent places on the (x, y) coordinate plane.

The coordinate space for rectangles and points is considered to have increasing values downward and to the right from its origin making this the normal, computer graphics oriented notion of (x, y) coordinates rather than the strict mathematical one.

The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.

Application code does not need to explicitly release the resources managed by each instance when those instances are no longer required, and thus no dispose() method is provided.
[中]此类的实例表示（x，y）坐标平面上的位置。
矩形和点的坐标空间被认为从原点向下和向右具有递增的值，这使得这是正常的、面向计算机图形学的（x，y）坐标概念，而不是严格的数学概念。
此类中的hashCode（）方法使用公共字段的值来计算哈希值。在散列集合中存储类的实例时，不要在插入对象后修改这些字段。
当不再需要每个实例时，应用程序代码不需要显式释放这些实例管理的资源，因此不提供dispose()方法。
