将图形封装在类中 [英] Encapsulate Graphing in a Class

问题描述

我希望将所有与绘图有关的例程放在与Form1类分开的类中.该图形将绘制在表单上的面板上.我有一个尝试执行我想要的操作的测试代码，但是paint事件处理程序无法正常工作.有人解决方案吗?

I wish to put all routines having to do with graphing in a class separate from the Form1 class. The graph is to be drawn on a panel located on the form. I have a test code that tries to do what I want but the paint event handler does not work right. Does anybody have a solution?

推荐答案

将其放入UserControl:这样便可以绘制自身.处理它的Paint事件，然后将MyGraphControl添加到窗体中-一切正常.

Make it into a UserControl: that way it can draw itself. Handle it''s Paint event, and add a MyGraphControl to your form - it should all work fine.

请查看我过去的解决方案:

Please see my past solution: How do I clear a panel from old drawing[^].

Please ask me your follow-up questions. The problem is pretty simple.
