VTK与MFC联合编程实现的单文档实例vtkSDI详解

1. 实例的编译运行

新建工程时，可以直接通过cmake生成，但如果工程没有编译完全或者安装成功的话，在安装目录没法找到GUISupport/MFC/VTKMFCSettings.cmake,从而无法正常新建工程。这里主要讲解手动新建工程的过程，以方便大家的学习

和进一步理解。

a.新建工程，然后将vtkSDI文件夹直接覆盖工程里面的文件，res文件可以不复制。

b.设置头文件

b.添加lib路径和文件

c.修改property里面的general选项里的character set的设置。

d.编译运行

e.选择vtkdata中的vtk文件，然后进行查看处理

 

值得注意的是，要运用vtk和MFC联合编程，编译VTK源代码的时候一定要选择vtk gui support里的MFC.

 

2.实例源码详解

学过MFC的基本都知道，MFC中view类主要处理显示视图，doc类处理文档，mainframe主要为整个窗口的和工程的设置管理。由此，VTK与MFC联合编程时，需要主要的是数据操作，以及显示要很好的与MFC中的结构结合，做到MVC分离的要求和规范，视图-模型和控制一定要处理开来，尤其是大工程的处理时，才能不混乱。
