Knowledge is not alone, it must be systematic. More my personal summary and related experience can be found in this column: Visual Studio .
The lack of knowledge can be found in the previous few articles.

The learning idea is:
- Copy the source code
Cylinder.cxxdown - Source code
Cylinder.cxxEnglish comment changed Chinese form programClinerVTKTest.cpp - Combining with the previously implemented Qt display example [VTK] VTK display ball example, use Visual Studio and Qt to build VTK on Windows , carry out project transplantation, and clarify the Qt display core
- Finally got the file
VTKTest.cpp
The effect is as follows:
VTKTest.cpp
#include "VTKTest.h"
VTKTest::VTKTest(QWidget* parent)
: QMainWindow(parent)
{
ui.setupUi(this);
}
VTKTest::~VTKTest()
