Home < Documentation < Labs < Qt5-and-VTK8This page documents the update of Slicer to use Qt 5.
Contents
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
- Current main integration branch for testing:
https://github.com/jcfr/Slicer/commits/support-qt5
- Work-in-progress branch that partially builds
- 2017-01:
- 2016-12:
- Superbuild configure command on mac using Qt 5.7 stock downloads
cmake \ -DQT_QMAKE_EXECUTABLE:FILEPATH=/Users/pieper/Qt/5.7/clang_64/bin/qmake \ -DCMAKE_PREFIX_PATH:PATH=/Users/pieper/Qt/5.7/clang_64/ \ -DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.9 \ -DSlicer_USE_PYTHONQT_WITH_TCL:BOOL=OFF \ -DSlicer_USE_SimpleITK:BOOL=OFF \ -DSlicer_USE_QtTesting:BOOL=OFF \ -DSlicer_BUILD_EXTENSIONMANAGER_SUPPORT:BOOL=OFF \ -DSlicer_QT_VERSION:STRING=5 \ ../Slicer
Platform Notes
Experimental build on Window:
- Visual Studio Community 2015
- Qt 5.7
- Include QtWebEngine and QtScript during install
- Select 2015 64 bit install
Known Issues
- Slice viewers do not have the expected size after changing layout
To Do List
All platforms
- Slicer build system upgrade: To be done
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) - See
Update use of QT4_* macros (see below) - See what is done in CTK- Port from QtWebKit to QtWebEngine
- Update of classes using WebKit to work with
WebEngineView
(these includes "Extension Manager", "Data Store", "Chart View" and `qMRMLExpandingWebView`). - `qSlicerWebWidget` should be improved, moved to CTK and used for all widgets making use of a web view.
- Update of classes using WebKit to work with
update PythonQt to the latest Qt version- Look at updating PythonQt to support QWebEngine
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
- Command line arguments to expose webgl and webengine debugging
./Slicer-build/Slicer --enable-experimental-web-platform-features --enable-unsafe-es3-apis --remote-debugging-port=12117 --use-gl=desktop
Linux
- fix fox `libpng warning: iCCP: known incorrect sRGB profile`
Minimal working release experimental build (no cli, ssl, simpleitk, ...) built on ubuntu 16.04, tested on debian 8
- needed to manually copy shared libraries:
- libasound.so.2
- libxslt.so.1
- libsmime3
- libstdc++.so.6 (glibc mismatch, needed GLIBCXX_3.4.21) should build instead with manylinux
- like on mac, need to create bin/platfrms and bin/sqldrivers and copy in platforms/libqxcb.so and sqldrivers/libqsqlite.so
Mac
- on Mac, QT_NO_OPENSSL is defined, but so is QSslError leading to redefined symbol [1](here).
- Mac crash in qSlicerUnitsSettingsPanelPrivate::addQuantity, appears to be corrupted model. partly addressed by r25855 . Most expedient solution is probably to disable the units settings panel in the application settings since is not widely used in the application.
- Add libqcocoa.dylib and libqsqlite.dylib to package for mac
mkdir Slicer-build/bin/Slicer.app/Contents/MacOS/sqldrivers cp ~/Qt/5.7/clang_64/plugins/sqldrivers/libqsqlite.dylib Slicer-build/bin/Slicer.app/Contents/MacOS/sqldrivers/ mkdir Slicer-build/bin/Slicer.app/Contents/MacOS/platforms cp ~/Qt/5.7/clang_64/plugins/platforms/libqcocoa.dylib Slicer-build/bin/Slicer.app/Contents/MacOS/platforms/
- Workarounds here:
https://gist.github.com/pieper/59de820ad08cf3c0f7a33926397e612d
Windows
qtstyleplugins library needs to be removed or ported to support windows- add declspec exports/imports
- create .lib for use in QTGUI
- support shared/static build?
- AppLauncher settings need to be update
- Add to PYTHONPATH: <superbuild>/VTKv7-build/bin/Debug (currently lib not bin)
- Add to PATH: <Qt>/5.7/msvc2013_64/bin
- Debug build is very slow - can it be improved?
SuperBuild Dependencies
- PythonQt:
Done- Need to update to Qt 5.7 in current PythonQt trunk (currently 5.6) and CommonTK PythonQt (currently 5.4)
- VTK
- Usage of QT4_ macros:

Migration Guide
To do items (partial list):
- update loadable modules to use new plugin macros
- any use of QWebKit needs to switch to QWebEngine
List of extensions that may require updates
TBD (probably all extensions need work)
Future works
