Slicer3:Loadable Modules:Phase1
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.
Create shared libraries for each of the static modules listed in Slicer3.cxx
loadable modules entry points
void* ModuleGUI void* ModuleLogic
That might be it, it'd be nice to have the module describe the necessary methods to call on the GUI and Logic pointer, but that might be Phase I-A. Within Slicer3_main, there doesn't seem to be much variation.
