如何添加工具箱为此.

具有相当数量的代码.我过去做的方式是创建一个基本的"shape"类.然后派生不同形状的类.每个形状都知道如何绘制自己以及它的位置.表单的绘画事件，遍历了一系列形状实例，并让它们都在表单上绘制自己.

With a fair amount of code. The way I''ve done it in the past, is to create a basic ''shape'' class. Then derive classes for different shapes. Each shape knows how to draw itself, and it''s location. The paint event of the form, goes over a collection of shape instances, and lets them all draw themselves on the form.
