VTK 9.1 + GUISupportQtQUICK + Qt5

Support
1

Hi! I built VTK 9.1 on windows 10 with GUISupportQtQuick enabled and QT 5. The build is done without any error. However, I am not able to import VTK in qml. Here is the error I get:

error
error1146×293 17.6 KB

I have defined the environment variable QML2_Import_PATH to where qmldir directory.

Any help would be much appreciated.

Thanks,
Parisa

I figured out what was missing based on:
GitHub - dezbracaty/QtVtk9.1: A qt vtk demo with vtk 9.1

After adding the following lines to main.cpp I was able to import VTK and render 3D volume:
qmlRegisterType(“VTK”, 9, 1, “VTKRenderWindow”);
qmlRegisterType(“VTK”, 9, 1, “VTKRenderItem”);
qmlRegisterType(“VTK”, 9, 1, “VTKWidget”);

In fact , there. are many ways to fix this . You can use qmlResisterType to let qt know this object , and you can make a qml plugin to let qt know this object too , There are other methods, mainly you can let qt know this type。the second way is in vtk-example.
And i am the author of the project.
