From Slicer3:Loadable_Modules:

   * runtime module discovery
   * module template
   * like CommandLineModuleFactory 


Starting at ~900 in Applications/GUI/Slicer3.cxx, static modules load occurs.

Using vtkSys tools to list shared libraries present. Use itk::DyanmicLoader to open libraries and call our specified entry points.

The actions taken for each module to be added could be queried from the found shared library using a LoadableModuleInfo class. Some of the information a library should provide:

  • vtkSlicerLogic pointer (maybe this is one of the defined entry points for a loadable module)
  • methods to call on the Logic pointer
  • vtkSlicerModulesGUI pointer (ditto)
  • methods to call on the GUI pointer
  • module name

LoadableModuleFactory (dervie from? Libs/ModuleDescriptionParser/ModuleFactory.cxx) handles this. Looks like ModuleFactory::ScanForSharedObjectModules does something very similar.
