| − | 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

| − | void* GetLoadableModuleGUI

| − | void* GetLoadableModuleLogic

| − | char* GetLoadableModuleDescription

| − | 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.
| |
| − | | |
| − | Slicer3.cxx also defines *_Init(Tcl_Interp* interp) functions and calls them for each module. Should this also be conditional for loadable modules? Does it require an additional entry point?

| − | | |
| − | | |
| − | Is there a header/source file that should be added to every module? Can we follow the CLP methodology and use an XML source and CMake driven tool to generate the necessary files?
