Detailed Description

Plugin class to expose a VTK C++ module to QML applications.

QQmlVTKPlugin registers various VTK C++ classes as QML types so that QtQuick applications can directly import and use these types from QML.

Importing the VTK module in QML

As part of VTK's compilation process, it would compile and install a qmldir file that provides the module definition and relevant plugin information required by QML to load VTK. To load the plugin, set the environment variable QML2_IMPORT_PATH to the path of the directory containing the qmldir file.

# /projects/Import has a sub-directory VTK.9.0/qmldir
$ export QML2_IMPORT_PATH=/projects/Import

Once the import path is set correctly, the module can be imported in the .qml file as follows:

import VTK 9.0

Registered types

The C++ classes exposed to QML and their associated typenames are as follows:

VTK C++ class	QML type
QQuickVTKRenderWindow	VTKRenderWindow
QQuickVTKRenderItem	VTKRenderItem
QQuickVTKInteractiveWidget	VTKWidget

Versioning

The VTK QML module follows the version number of the VTK source tree. For example, if compiled against VTK 9.0.x, the VTK module version will be 9.0
