获取给定其项目句柄的Canvas小部件上项目的当前坐标？ [英] Get the current coordinates of an item on a Canvas widget given its item handle?

问题描述

通过阅读文档（ http://effbot.org/tkinterbook/canvas.htm#reference ），在我看来没有办法做到这一点。只是想确保我没有记错。 （即，例如，如果要进行边界检查，则必须在程序中内部存储各个项目的坐标。[例如，在移动椭圆形之前，检查它不会撞到墙壁上，用一条线表示）当前画布，其坐标信息也已存储。]）

From reading the docs (http://effbot.org/tkinterbook/canvas.htm#reference), there doesn't appear to me to be a way to do this. Just wanted to make sure I hadn't made a mistake. (I.e. one would have to internally store the coordinates of various items in a program if one wanted to do boundary checking, for example. [e.g. Check, before moving an oval, that it will not bump into a wall, represented by a line on the current canvas, the coordinate information of which is also stored.])

推荐答案

使用坐标方法：

coords = the_canvas.coords(item_id)
