I am not sure if it makes sense to spend time on a solution like this because the number of use cases is quite limited. Surely one could create simple linear chains of modules, but creating anything more complex would be quite inconvenient (e.g. a process where module C uses output of modules A and B). I believe that a graphical model builder (where a box = module, an arrow = data transfer) is the only long term solution, something like this: http://grass.osgeo.org/wiki/WxGUI_Modeler Martin _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
