Initialization

• Create the Module directory

cd Slicer4
python Utilities/Scripts/ModuleWizard.py MY_MODULE_NAME

Where you replace MY_MODULE_NAME with the name of the module you want (e.g. HelloWorld) Note: on Windows

..\Slicer4-Superbuild\python-build\PCBuild\python.exe UtilitiesScripts\ModuleWizard.py MY_MODULE_NAME

• Edit the file Slicer4/Modules/Loadable/CMakeLists.txt

Add the name of your module at the end of the qtmodules variable assignment:

...
set(qtmodules
  ...
  MY_MODULE_NAME
  )
...

• Compile

cd ../Slicer4-Superbuild/Slicer-build;
make -j4

• Start Slicer and verify the module is present (listed under "Module Template")

./Slicer

• Open the designer via the launcher

./Slicer --designer

• Edit the module UI file: QTModules/MY_MODULE_NAME/Resources/UI/qSlicerMY_MODULE_NAMEModule.ui
