Which version of MITK do you use? I guess you are reading an outdated version
of our tutorial (which would also explain why you are using the deprecated
DataNodeFactory instead of IOUtils). There are some major differences in the
current version (MITK 2015.05): http://docs.mitk.org/2015.05/Step01Page.html
Do you really want to code your own application from the very beginning instead
of just using/extending the full-featured MitkWorkbench?
Regarding MITK images in QtWidgets: I found a code snippet in my archive which
I wrote a few years ago. I cannot guarantee that it will still work out of the
box but you should get the idea of what is necessary to accomplish that task
(see it as pseudo code). Maybe Rostislav has a better snippet (as far as I
remember he displays images in his widgets, too - added him explicitly to Cc):

mitk::ExtractSliceFilter::New();
extractSliceFilter->SetInterpolationMode(mitk::ExtractSliceFilter::RESLICE_CUBIC);

extractSliceFilter->SetWorldGeometry(planarFigure->GetGeometry2D());

Hi Stefan,
so the first problem was solved...but then another came.
As I was saying earlier Im using the Tutorial Part1 and all I want to change is
the way an image is used. Instead of having it in the command argument thingy I
want to open an image using QfileDialog which works but its not displaying the
image yet.
Heres the source code for clarification:
MainWindow.cpp
//Construktor Destruktor...
void MainWindow::on_openButton_pressed()
{
// Create a DataStorage
mitk::StandaloneDataStorage::Pointer ds =
mitk::StandaloneDataStorage::New();
// Create a DataNodeFactory to read a data format supported
mitk::DataNodeFactory::Pointer reader = mitk::DataNodeFactory::New();
QString imagePath = QFileDialog::getOpenFileName(this,
"Select one or more files to open",
"/home",
"Images (*.DCM)");
char* filename;
filename = new char[imagePath.toStdString().size() + 1];
strcpy(filename, imagePath.toStdString().c_str());
try
{
reader->SetFileName(filename);
reader->Update();
// Add the node to the DataStorage
ds->Add(reader->GetOutput());
}
catch (...)
{
fprintf(stderr, "Could not open file %s \n\n", filename);
exit(2);
}
//create render window
QmitkRenderWindow *scene;
// Tell the RenderWindow which part of the datastorage to render
scene->GetRenderer()->SetDataStorage(ds);
// Initialize the RenderWindow
mitk::TimeGeometry::Pointer geo =
ds->ComputeBoundingGeometry3D(ds->GetAll());
mitk::RenderingManager::GetInstance()->InitializeViews(geo);
// Select a slice
mitk::SliceNavigationController::Pointer sliceNaviController =
scene->GetSliceNavigationController();
if (sliceNaviController)
sliceNaviController->GetSlice()->SetPos(0);
//Show image
scene->show();
scene->resize(256, 256);
ds = NULL;
The QmitkRegisterClasses() Funktion is in main.cpp, but causes the following
error when not commented out:
error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl
QmitkRegisterClasses(void)" (__imp_?QmitkRegisterClasses@@YAXXZ) referenced in
function main
Also, is there a way to have the image show up in a widget of my ui-file
(QGraphicsView)? How can they be connected?
Thank you in advance
Best regards
Sina

I guess in that case it is the MODULES line at the end. :)
(Please keep the conversation on the list so that others can benefit from it as
well, thank you)

Hi Stefan,
thanks for the fast response.
I'm not quite sure where to add that mentioned line.
This is what my cmakelists looks like:
project(AwesomeApp)
set(_app_options)
if(${MY_PROJECT_NAME}_SHOW_CONSOLE_WINDOW)
list(APPEND _app_options SHOW_CONSOLE)
endif()
# Plug-ins listed below will not be
# - added as a build-time dependency to the executable
# - listed in the provisioning file for the executable
# - installed if they are external plug-ins
set(_exclude_plugins
)
mitkFunctionCreateBlueBerryApplication(
NAME ${MY_APP_NAME}
DESCRIPTION "MITK - ${MY_APP_NAME} Application"
EXCLUDE_PLUGINS ${_exclude_plugins}
${_app_options}
)
mitk_use_modules(TARGET ${MY_APP_NAME}
MODULES MitkAppUtil
PACKAGES Qt4|QtGui Qt5|Widgets
)
Best

Hi Sina,
it seems that the linker isn’t able to find mitk::DataNodeFactory, which is
located in the MitkLegacyIO module. Add MitkLegacyIO to the DEPENDS line of
your module CMakeLists.txt.
Best,
Stefan

Hello,
I am new to MITK and am trying to use the MITK Tutorial to display an image in
my own Qt User Interface.
When trying to build my project the following error occurs:
7> Creating library
C:/MITK-pt-sb/AwesomeProject-build/bin/Debug/AwesomeApp.lib and object
C:/MITK-pt-sb/AwesomeProject-build/bin/Debug/AwesomeApp.exp
7>MainWindow.obj : error LNK2019: unresolved external symbol
"__declspec(dllimport) public: static class itk::SmartPointer<class
mitk::DataNodeFactory> __cdecl mitk::DataNodeFactory::New(void)"
(__imp_?New@DataNodeFactory@mitk@@SA?AV?$SmartPointer@VDataNodeFactory@mitk@@@itk@@XZ)
referenced in function "public: void __cdecl
MainWindow::on_openButton_pressed(void)"
(?on_openButton_pressed@MainWindow@@QEAAXXZ)
I know this is a linker problem but I dont know which library to link or what
else has to be done to solve this error.
I hope anyone can help
Best Regards
Sina
