VTK 6.3.0 Qt 5.4 MinGW 4.9.1 Configuration 配置

 

Download VTK 6.3.0

Download Qt 5.4 with MinGW 4.9.1

Download CMake 3.2.0

 

I assume you've already installed Qt 5.4 with MinGW 4.9.1 and CMake 3.2.0 correctly.

 

Pre-process the VTK:

Open CMakeLists.txt in your extracted VTK-6.3.0 folder, find set(VTK_USE_WIN32_THREADS 1), change it to: set(VTK_USE_PTHREADS 1)

mark_as_advanced(VTK_THREAD_MODEL)
if(CMAKE_USE_WIN32_THREADS_INIT)
  set(VTK_USE_PTHREADS 1)
  set(CMAKE_THREAD_LIBS_INIT "")
elseif(CMAKE_USE_PTHREADS_INIT)
  set(VTK_USE_PTHREADS 1)
  if(CMAKE_HP_PTHREADS_INIT)
    set(VTK_HP_PTHREADS 1)
  endif()
elseif(CMAKE_USE_SPROC_INIT)
  set(VTK_USE_SPROC 1)
endif()
set(CMAKE_THREAD_LIBS "${CMAKE_THREAD_LIBS_INIT}" CACHE STRING "Thread library used.")

 

Open C:\VTK6.3.0\VTK-6.3.0\ThirdParty\libxml2\vtklibxml2\threads.c , add #undef HAVE_WIN32_THREADS after #include "libxml.h"

#define IN_LIBXML
#include "libxml.h"
#undef HAVE_WIN32_THREADS
#include <string.h>

 

Compile the VTK:

Start CMake 3.2.0, fill the source and destination:

source: C:/VTK6.3.0/VTK-6.3.0

destination: C:/VTK6.3.0/build

Click Configure and use MinGW Makefiles to complie.

 

When first configure is done, select Grouped and Advanced.

Go to CMAKE->CMAKE_INSTALL_PREFIX, change the value to C:/VTK6.3.0/MinGW

Go to Module, select Module_vtkGUISupportQt、Module_vtkGUISupportQtOpenGL、Module_vtkGUISupportQtSQL、Module_vtkGUISupportQtWebkit、Module_vtkRenderingQt、Module_vtkViewsQt

Go to VTK, select VTK_Group_Qt

Go CMake->CMAKE_BUILD_TYPE, change value to Release

Click Add Entry, add QT_QMAKE_EXECUTABLE as Name, PATH as Type, C:/Qt/5.4/mingw491_32/bin/qmake.exe as value:

 

Click Add Entry, add CMAKE_PREFIX_PATH as Name, PATH as Type, C:/Qt/5.4/mingw491_32 as value:

 

Click Configure again, and you gonna get an error said: "Error in configuration processs, project files may be invalid."

Go to Ungrouped Entries->QT_VTK_VERSION, change value to 5, then click Configure again.

After configure is done, click Generate.

 

Go back to your build folder, open command line, type: mingw32-make

Wait a long time for make process, have a cup of coffee :)

After make is done, type mingw32-make install

 

Now, the configuration is done, enjoy it :)

 

Use the VTK:

Create new Qt Widgets, change .pro file to:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = ImageViewer
TEMPLATE = app

SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

INCLUDEPATH += C:\VTK6.3.0\MinGW\include\vtk-6.3

LIBS += -LC:\\VTK6.3.0\\MinGW\\bin \
        libvtkGUISupportQt-6.3 \
        libvtkIOImage-6.3 \
        libvtkInteractionImage-6.3 \
        libvtkRenderingCore-6.3 \
        libvtkCommonExecutionModel-6.3 \
        libvtkCommonCore-6.3 \
        libvtkRenderingOpenGL-6.3 \
        libvtkInteractionStyle-6.3 \

 

and the main.cpp :

#include "mainwindow.h"
#include <QApplication>

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL)
VTK_MODULE_INIT(vtkInteractionStyle)

#include "vtkImageViewer.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkRenderer.h"
#include "vtkPNGReader.h"
#include "QVTKWidget.h"
#include "vtkImageData.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QVTKWidget widget;

    char filename[] = "img.png";
    vtkPNGReader* reader = vtkPNGReader::New();
    reader->SetFileName(filename);
    reader->Update();

    vtkImageViewer* imageView = vtkImageViewer::New();
    imageView->SetInputConnection(reader->GetOutputPort());

    widget.SetRenderWindow(imageView->GetRenderWindow());
    imageView->SetupInteractor(widget.GetRenderWindow()->GetInteractor());
    imageView->SetColorLevel(138.5);
    imageView->SetColorWindow(233);

    int *dims = reader->GetOutput()->GetDimensions();
    widget.resize(dims[0], dims[1]);
    widget.show();

    app.exec();

    imageView->Delete();
    reader->Delete();
    return 0;
}

 

Use the QVTKWidget in Qt Designer:

Copy libQVTKWidgetPlugin.dll from C:\VTK6.3.0\MinGW\plugins\designer to:

C:\Qt\5.4\mingw491_32\plugins\designer

C:\Qt\Tools\QtCreator\bin\plugins\designer

 

If you use independent Qt Designer, you will find QVTK after Display Widgets.

If you want to use QVTKWidget inside QtCreator, it might not show in the left list, but you can promote a QWidget to QVTKWidget with including the QVTKWidget.h
