This page will document experiments related to the upgrade of Slicer base to Qt5.

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

  • 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.


  • CTK support: Done Check.svg


  • ITKv4: NA Check.svg


  • PythonQt: Done Check.svg


  • Slicer build system upgrade: To be done UnderConstruction.png
    • Add a switch similar to what is done in CTK (Add option Slicer_QT_VERSION that can be set to either 4 or 5)
    • Update use of QT4_* macros (see below)
    • 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


  • Usage of QT4_ macros:
