    * runtime module discovery

----
 
 
 
 
 
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* 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.
 
 
 
==== loadable module support ====
 
 
 
 
 
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?
 
 
 
==== SVN branch ====
