1 增加按钮、增打开文档提示
今天又来更新文档了，今天这个四视图中又增加了点东西，今天这篇是添上上篇的坑的。三个按钮终于实现了。在实现三个按钮的情况下，还给他增加了一个打开文件夹的提示，不过这英文用的好像是不咋对，凑乎看吧，如下图：
还记得在上上片文中中增加按钮失败那，哪里使用了QVTKOpenGLWidget，死活都没法实现，我个人感觉应该是因为布局的问题。这次再升级VTK9.0.3后，使用了QVTKOpenGLNativeWidget 实现了这个功能。
2 自定义模块"VTKRenderWidget"
这里我自己定义了模块VTKRenderWidget，包含一个QVTKOpenGLNativeWidget 和三个QPushbutton ，如下图所示
2.1 vtkrenderwidget.h

在我的这自定义模块中，还使用了自己定义的QVTKOpenGLNativeWidget名字为MyQVTKOpenGLNativeWidget.
3 重写模块“QVTKOpenGLNativeWidget”
其实目前来看，这个类和原生基础的QVTKOpenGLNativeWidget没有太多区别。目前只是增加了鼠标双击事件。
