Home < Documentation < Labs < Qt5-and-VTK8

This page documents the update of Slicer to use Qt 5.

Overview

Because Qt4 is not actively developed (as documented here support ended), we need to work toward supporting Qt5. This page summarizes support status of the various components of Slicer stack and remaining tasks.

Status

To Do List

  • Slicer build system upgrade: To be done UnderConstruction.png
    • Add Slicer_QT_VERSION option that could be set to either 4 or 5 - See what is done in CTK
    • Fix qRestAPI to support Qt5 (or turn off Slicer_BUILD_EXTENSIONMANAGER_SUPPORT for testing)
    • Update use of QT4_* macros (see below) - See what is done in CTK
      • The QT5_ versions of the macros appear to be directly compatible
    • Port from QtWebKit to QtWebEngine
    • Fix differences in plugin loading
    • Update packaging scripts (SlicerBlockInstallQt.cmake, SlicerCPackBundleFixup.cmake)
    • Update build script to support qt5 (see https://github.com/jcfr/qt-easy-build )
    • Update Slicer build instruction on developer wiki
  • PythonQt: Done Check.svg


  • CTK support: Done Check.svg


  • VTK
    • Support for QVTKWidget/QVTKWidget2: Done Check.svg
    • QML support for VTK render windows: To Be Done UnderConstruction.png
      • Not yet required by Slicer core
      • Jc@Kitware: We experimented with few approaches internally.


  • ITKv4: NA Check.svg


  • Usage of QT4_ macros:
