大家好，

我有一个sdi项目.我试图通过创建一个单独的(CLine)类来画一条线.我的基类是CScrollView.从scrollview我通过创建一个对象来调用CLine类的成员函数.我在运行时遇到断言错误，并且在调整大小时行也超出了窗口.我的问题是CLIne的基类是什么，以及如何使用视图管理行位置，请问有谁可以帮我...

Hai all,

推荐答案

我想这样做的逻辑方法是，使CLine称为Line(C标准适用于MFC类，并且是dumb)，并具有没有基类.您的窗口应保留Line对象的集合，并在Paint事件中对其进行迭代并绘制线条.就目前而言，这听起来像是您正在创建子窗口，如果您希望这些行存在于SDI窗口中并附加到它上，那是不明智的.

I would imagine the logical way to do this, would be to make CLine called Line ( the C standard is for MFC classes, and is dumb ), and to have no base class. Your window should keep a collection of Line objects, and iterate over it in your Paint event and draw the lines. As it stands, it sounds like you''re creating child windows, which is not wise, if you want the lines to exist inside your SDI window and be attached to it.
