Thank you very much for your prompt answer. As I wrote to Dan, we have to use QtCreator for the development here. Then I have access only for qmake and I can edit project files for it. If QVTKOpenGLWidget is the only VTK widget class supported for Qt5 then I ave to find out how to insert such an object into the UI form file of QT.<br>

Kind regards,<br>

Also, when working with VTK, it will be a lot easier to switch to using CMake instead of Qt project files (QtCreator supports CMake). Look at the examples Dan linked to. You will have to update the CMakelists.txt file for Qt. You will probably have to add the following:<br>
<br>
FIND_PACKAGE(Qt5Core REQUIRED)<br>
FIND_PACKAGE(Qt5Widgets REQUIRED)<br>
<br>
and update the target_link_libraries line(add Qt5::Widget) , e.g.,:<br>
<br>
target_link_libraries(QtBarCha<wbr>rt Qt5::Widgets ${VTK_LIBRARIES})<br>

This is unrelated to the error you are seeing however:<br>
<br>
For Qt5 you'll need to use QVTKOpenGLWidget rather than QVTKWidget. See<br>

<<a href="https://lorensen.github.io/VTKExamples/site/Cxx/" rel="noreferrer" target="_blank">https://lorensen.github.io/VT<wbr>KExamples/site/Cxx/</a>><br>
All examples are converted to Qt5. Also, VTK master has a number of<br>
examples that have been converted to Qt5: Examples/GUI/Qt<br>

Hope this helps,<br>

Dear all,<br>
<br>
In CMake I generated a solution project of VTK-8.0.1 with Qt5<br>
support for MSVS2013. After having run the ALL_BUILD and INSTALL<br>
projects with the install prefix C:\VTK\8.0.1 in VM2013 I could<br>
installed the Win32 bit binaries of VTK 8.0.1 in that folder.<br>
The header files and the libraries are located in<br>
C:\VTK\8.0.1\include\vtk-8.0 and<br>
C:\VTK\8.0.1\lib.<br>
<br>
I copied the file QVTKWidgetPlugin.dll from the VTK binary<br>
folders to the plugin folder of QTCreator, which uses QT 5.8<br>
msvs2013 32 bit version.<br>
<br>
Then I set the include and library paths and added all the VTK<br>
libary files from C:\VTK\8.0.1\lib for the linker setting in the<br>
project file<br>
of a QT application in QtCreator:<br>

However, if I add a QVTKWidget on the UI file of the<br>
application, include the file QVTKWidget.h in the header file of<br>
the application and I try to link it in QtCreator with the<br>
32-bit VTK and Qt libraries, MSVS2013 (in the toolchain of<br>
QtCreator) sends error messages for unresolved external symbols<br>
for all the functions/classes belonging to the QVTKWidget, such as<br>
<br>
distortionpage.obj:-1: Fehler: LNK2019: unresolved external<br>
symbol "__declspec(dllimport) public: __thiscall<br>
QVTKWidget::QVTKWidget(class QWidget *,class QFlags<enum<br>
Qt::WindowType>)"<br>
(__imp_??0QVTKWidget@@QAE@PAVQ<wbr>Widget@@V?$QFlags@W4WindowType<wbr>@Qt@@@@@Z)<br>
referenced in function "public: void __thiscall<br>
Ui_DistortionPage::setupUi(cla<wbr>ss QWidget *)"<br>
(?setupUi@Ui_DistortionPage@@Q<wbr>AEXPAVQWidget@@@Z)<br>
<br>
<br>
It seems that the linker could not find the libary for the<br>
QVTKWidget plugin, which is loaded since I could chose QtWidget<br>
from the widget list in the UI form editor in QtCreator. I do<br>
not see any ABI issue here since I use the 32 bit mscv2103<br>
version of Qt and I also compiled and linked the 32 bit version<br>
of VTK libaries and plugin files with MSVS2013. I am wondering<br>
if anybody could make VTK-8.1 working with Qt. Thanks a lot.<br>

Hi Zoltan,<br>
<br>
I don't know how the widget should be installed or set up in<br>
a project, but you could just search for the header file and<br>
point INCLUDEPATH to the folder that contains it.<br>

Hi Joni,<br>
<br>
I see. However I found MSCV2013 32 bit version for Qt<br>
5.8. I install<br>
that version and I built the VTK binaries for win32<br>
platform with<br>
MVS2013. After having copied the VTK plugin file into<br>
the plugin folder<br>
of QtCreator I could launch it successfully. The<br>
QVTKWidget is in the<br>
Widget list of QtCreator now. I could insert a<br>
QVTKWidget in the UI form<br>
as well. The only problem now is that QtCreator cannot<br>
find the header<br>
file for QVTKWidget. It is not cleat how to set the<br>
INCLUDEPATH in the<br>
project file since VS2103 did not create a separate<br>
include folder in<br>
the target folder C:/VTK/bin for the VTK binaries. Only<br>
the library<br>
files have a separate folder, C:/VTK/bin/lib/Release.<br>
<br>

Hi Joni,<br>
<br>
Thank you very much for your answer. Then I try<br>
to install everything<br>
from scratch. The only prolem is I have only<br>
MSVC 2103 and the only<br>
option in the selection list of the online<br>
installer for MSVC 2013 is<br>
the 64 bit version. Is there somewhere an<br>
installer on your website wich<br>
provides a relatively new Qt version with MSVC<br>
2103 32 bit version?<br>
Thank you very much for your help.<br>
<br>
<br>
No, but you could compile it from source yourself.<br>
However, note that you cannot build plugins for new<br>
Qt Creator with MSVC 2013 as it uses different ABI.<br>
You could use MSVC 2015 or MSVC 2017.<br>
<br>
Or you could build 64bit version of Qt Creator from<br>
source with that Qt version you have installed.<br>
<br>
